Some Native Americans Had Oceanic Ancestors

This week has seen a flurry of new scientific and news articles.  What has been causing such a stir?  It appears that Australian or more accurately, Australo-Melanese DNA has been found in South America’s Native American population. In addition, it has also been found in Aleutian Islanders off the coast of Alaska.  In case you aren’t aware, that’s about 8,500 miles as the crow flies.  That’s one tired crow.  As the person paddles or walks along the shoreline, it’s even further, probably about 12,000 miles.

Aleutians to Brazil

Whatever the story, it was quite a journey and it certainly wasn’t all over flat land.

This isn’t the first inkling we’ve had.  Just a couple weeks ago, it was revealed that the Botocudo remains from Brazil were Polynesian and not admixed with either Native, European or African.  This admixture was first discovered via mitochondrial DNA, but full genome sequencing confirmed their ancestry and added the twist that they were not admixed – an extremely unexpected finding.  This is admittedly a bit confusing, because it implies that there were new Polynesian arrivals in the 1600s or 1700s.

Unlikely as it seems, it obviously happened, so we set that aside as relatively contemporary.

The findings in the papers just released are anything but contemporary.

The First Article

The first article in Science, “Genomic evidence for the Pleistocene and recent population history of Native Americans” by Raghaven et al published this week provides the following summary (bolding is mine):

How and when the Americas were populated remains contentious. Using ancient and modern genome-wide data, we find that the ancestors of all present-day Native Americans, including Athabascans and Amerindians, entered the Americas as a single migration wave from Siberia no earlier than 23 thousand years ago (KYA), and after no more than 8,000-year isolation period in Beringia. Following their arrival to the Americas, ancestral Native Americans diversified into two basal genetic branches around 13 KYA, one that is now dispersed across North and South America and the other is restricted to North America. Subsequent gene flow resulted in some Native Americans sharing ancestry with present-day East Asians (including Siberians) and, more distantly, Australo-Melanesians. Putative ‘Paleoamerican’ relict populations, including the historical Mexican Pericúes and South American Fuego-Patagonians, are not directly related to modern Australo-Melanesians as suggested by the Paleoamerican Model.

This article in EurekAlert and a second one here discuss the Science paper.

Raghaven 2015

Migration map from the Raghaven paper.

The paper included the gene flow and population migration map, above, along with dates.

The scientists sequenced the DNA of 31 living individuals from the Americas, Siberia and Oceana as follows:

Siberian:

  • Altai – 2
  • Buryat – 2
  • Ket – 2
  • Kiryak – 2
  • Sakha – 2
  • Siberian Yupik – 2

North American Native:

  • Tsimshian (number not stated, but by subtraction, it’s 1)

Southern North American, Central and South American Native:

  • Pima – 1
  • Huichol -1
  • Aymara – 1
  • Yakpa – 1

Oceana:

  • Papuan – 14

The researchers also state that they utilized 17 specimens from relict groups such as the Pericues from Mexico and Fuego-Patagonians from the southernmost tip of South America.  They also sequenced two pre-Columbian mummies from the Sierra Tarahumara in northern Mexico.  In total, 23 ancient samples from the Americas were utilized.

They then compared these results with a reference panel of 3053 individuals from 169 populations which included the ancient Saqqaq Greenland individual at 400 years of age as well as the Anzick child from Montana from about 12,500 years ago and the Mal’ta child from Siberia at 24,000 years of age.

Not surprisingly, all of the contemporary samples with the exception of the Tsimshian genome showed recent western Eurasian admixture.

As expected, the results confirm that the Yupik and Koryak are the closest Eurasian population to the Americas.  They indicate that there is a “clean split” between the Native American population and the Koryak about 20,000 years ago.

They found that “Athabascans and Anzick-1, but not the Greenlandis Inuit and Saqqaq belong to the same initial migration wave that gave rise to present-day Amerindians from southern North America and Central and South America, and that this migration likely followed a coastal route, given our current understanding of the glacial geological and paleoenvironmental parameters of the Late Pleistocene.”

Evidence of gene flow between the two groups was also found, meaning between the Athabascans and the Inuit.  Additionally, they found evidence of post-split gene flow between Siberians and Native Americans which seems to have stopped about 12,000 years ago, which meshes with the time that the Beringia land bridge was flooded by rising seas, cutting off land access between the two land masses.

They state that the results support all Native migration from Siberia, contradicting claims of an early migration from Europe.

The researchers then studied the Karitiana people of South America and determined that the two groups, Athabascans and Karitiana diverged about 13,000 years ago, probably not in current day Alaska, but in lower North America.  This makes sense, because the Clovis Anzick child, found in Montana, most closely matches people in South America.

By the Clovis period of about 12,500 years ago, the Native American population had already split into two branches, the northern and southern, with the northern including Athabascan and other groups such as the Chippewa, Cree and Ojibwa.  The Southern group included people from southern North America and Central and South America.

Interestingly, while admixture with the Inuit was found with the Athabascan, Inuit admixture was not found among the Cree, Ojibwa and Chippewa.  The researchers suggest that this may be why the southern branch, such as the Karitiana are genetically closer to the northern Amerindians located further east than to northwest coast Amerindians and Athabascans.

Finally, we get to the Australian part.  The researchers when trying to sort through the “who is closer to whom” puzzle found unexpected results.  They found that some Native American populations including Aleutian Islanders, Surui (Brazil) and Athabascans are closer to Australo-Melanesians compared to other Native Americans, such as Ojibwa, Cree and Algonquian and South American Purepecha (Mexico), Arhuaco (Colombia) and Wayuu (Colombia, Venezuela).  In fact, the Surui are one of the closest populations to East Asians and Australo-Melanese, the latter including Papuans, non-Papuan Melanesians, Solomon Islanders and hunter-gatherers such as Aeta. The researchers acknowledge these are weak trends, but they are nonetheless consistently present.

Dr. David Reich, from Harvard, a co-author of another paper, also published this past week, says that 2% of the DNA of Amazonians is from Oceana.  If that is consistent, it speaks to a founder population in isolation, such that the 2% just keeps getting passed around in the isolated population, never being diluted by outside DNA.  I would suggest that is not a weak signal.

The researchers suggest that the variance in the strength of this Oceanic signal suggests that the introduction of the Australo-Melanese occurred after the initial peopling of the Americas.  The ancient samples cluster with the Native American groups and do not show the Oceanic markers and show no evidence of gene flow from Oceana.

The researchers also included cranial morphology analysis, which I am omitting since cranial morphology seems to have led researchers astray in the past, specifically in the case of Kennewick man.

One of the reasons cranial morphology is such a hotly debated topic is because of the very high degree of cranial variance found in early skeletal remains.  One of the theories evolving from the cranial differences involving the populating of the Americans has been that the Australo-Melanese were part of a separate and earlier migration that gave rise to the earliest Americans who were then later replaced by the Asian ancestors of current day Native Americans.  If this were the case, then the now-extinct Fuego-Patagonains samples from the location furthest south on the South American land mass should have included DNA from Oceana, but it didn’t.

The Second Article

A second article published this week, titled “’Ghost population’ hints at long lost migration to the Americas” by Ellen Callaway discusses similar findings, presented in a draft letter to Nature titled “Genetic evidence for two founding populations of the Americas” by Skoglund et al.  This second group discovers the same artifact Australo-Melanesian DNA in Native American populations but suggests that it may be from the original migration and settlement event or that there may have been two distinct founding populations that settled at the same time or that there were two founding events.

EurekAlert discusses the article as well.

It’s good to have confirmation and agreement between the two labs who happened across these results independently that the Australo-Melanesian DNA is present in some Native populations today.

Their interpretations and theories about how this Oceanic DNA arrived in some of the Native populations vary a bit, but if you read the details, it’s really not quite as different as it first appears from the headlines.  Neither group claims to know for sure, and both discuss possibilities.

Questions remain.  For example, if the founding group was small, why, then, don’t all of the Native people and populations have at least some Oceanic markers?  The Anzick Child from 12,500 years ago does not.  He is most closely related to the tribes in South America, where the Oceanic markers appear with the highest frequencies.

In the Harvard study, the scientists fully genome sequenced 63 individuals without discernable evidence of European or African ancestors in 21 Native American populations, restricting their study to individuals from Central and South America that have the strongest evidence of being entirely derived from a homogenous First American ancestral population.

Their results show that the two Amazonian groups, Surui and Karitians are closest to the “Australasian populations, the Onge from the Andaman Island in the Bay of Bengal (a so-called ‘Negrito’ group), New Guineans, Papuans and indigenous Australians.”  Within those groups, the Australasian populations are the only outliers – meaning no Africans, Europeans or East Asian DNA found in the Native American people.

When repeating these tests, utilizing blood instead of saliva, a third group was shown to also carry these Oceanic markers – the Xavante, a population from the Brazilian plateau that speaks a language of the Ge group that is different from the Tupi language group spoke by the Karitians and Surui.

Skoglund 2015-2

The closest populations that these Native people matched in Oceana, shown above on the map from the draft Skoglund letter, were, in order, New Guineans, Papuans and Andamanese.  The researchers further state that populations from west of the Andes or north of the Panama isthmus show no significant evidence of an affinity to the Onge from the Andaman Islands with the exception of the Cabecar (Costa Rica).

That’s a very surprising finding, given that one would expect more admixture on the west, which is the side of the continent where the migration occurred.

The researchers then compared the results with other individuals, such as Mal’ta child who is known to have contributed DNA to the Native people today, and found no correlation with Oceanic DNA.  Therefore, they surmised that the Oceanic admixture cannot be explained by a previously known admixture event.

They propose that a mystery population they have labeled as “Population Y” (after Ypykuera which means ancestor in the Tupi language family) contributed the Australasian lineage to the First Americans and that is was already mixed into the lineage by the time it arrived in Brazil.

According to their work, Population Y may itself have been admixed, and the 2% of Oceanic DNA found in the Brazilian Natives may be an artifact of between 2 and 85% of the DNA of the Surui, Karitiana and Xavante that may have come from Population Y.  They mention that this result is striking in that the majority of the craniums that are more Oceanic in Nature than Asiatic, as would be expected from people who migrated from Siberia, are found in Brazil.

They conclude that the variance in the presence or absence of DNA in Native people and remains, and the differing percentages argue for more than one migration event and that “the genetic ancestry of Native Americans from Central and South America cannot be due to a single pulse of migration south of the Late Pleistocene ice sheets from a homogenous source population, and instead must reflect at least two streams of migration or alternatively a long drawn out period of gene flow from a structured Beringian or Northeast Asian source.”

Perhaps even more interesting is the following statement:

“The arrival of population Y ancestry in the Americas must in any scenario have been ancient: while Population Y shows a distant genetic affinity to Andamanese, Australian and New Guinean populations, it is not particularly closely related to any of them, suggesting that the source of population Y in Eurasia no longer exists.”

They further state they find no admixture indication that would suggest that Population Y arrived in the last few thousand years.

So, it appears that perhaps the Neanderthals and Denisovans were not the only people who were our ancestors, but no longer exist as a separate people, only as an admixed part of us today.  We are their legacy.

The Take Away

When I did the Anzick extractions, we had hints that something of this sort might have been occurring.  For example, I found surprising instances of haplogroup M, which is neither European, African nor Native American, so far as we know today.  This may have been a foreshadowing of this Oceanic admixture.  It may also be a mitochondrial artifact.  Time will tell.  Perhaps haplogroup M will turn out to be Native by virtue of being Oceanic and admixed thousands of years ago.  There is still a great deal to learn.  Regardless of how these haplogroups and Oceanic DNA arrived in Brazil in South America and in the Aleutian Islands off of Alaska, one thing is for sure, it did.

We know that the Oceanic DNA found in the Brazilian people studied for these articles is not contemporary and is ancient.  This means that it is not related to the Oceanic DNA found in the Botocudo people, who, by the way, also sport mitochondrial haplogroups that are within the range of Native people, meaning haplogroup B, but have not been found in other Native people.  Specifically, haplogroups B4a1a1 and B4a1a1a.  Additionally, there are other B4a1a, B4a1b and B4a1b1 results found in the Anzick extract which could also be Oceanic.  You can see all of the potential and confirmed Native American mitochondrial DNA results in my article “Native American Mitochondrial Haplogroups” that I update regularly.

We don’t know how or when the Botocudo arrived, but the when has been narrowed to the 1600s or 1700s.  We don’t know how or when the Oceanic DNA in the Brazilian people arrived either, but the when was ancient.  This means that Oceanic DNA has arrived in South America at least twice and is found among the Native peoples both times.

We know that some Native groups have some Oceanic admixture, and others seem to have none, in particular the Northern split group that became the Cree, Ojibwa, Algonquian, and Chippewa.

We know that the Brazilian Native groups are most closely related to Oceanic groups, but that the first paper also found Oceanic admixture in the Aleutian Islands.  The second paper focused on the Central and South American tribes.

We know that the eastern American tribes, specifically the Algonquian tribes are closely related to the South Americans, but they don’t share the Oceanic DNA and neither do the mid-continent tribes like the Cree, Ojibwa and Chippewa.  The only Paleolithic skeleton that has been sequenced, Anzick, from 12,500 years ago in Montana also does not carry the Oceanic signature.

In my opinion, the disparity between who does and does not carry the Oceanic signature suggests that the source of the Oceanic DNA in the Native population could not have been a member of the first party to exit out of Beringia and settle in what is now the Americas.  Given that this had to be a small party, all of the individuals would have been thoroughly admixed with each other’s ancestral DNA within just a couple of generations.  It would have been impossible for one ancestor’s DNA to only be found in some people.  To me, this argues for one of two scenarios.

First, a second immigration wave that joined the first wave but did not admix with some groups that might have already split off from the original group such as the Anzick/Montana group.

Second, multiple Oceanic immigration events.  We still have to consider the possibility that there were multiple events that introduced Oceanic DNA into the Native population.  In other words, perhaps the Aleutian Islands Oceanic DNA is not from the same migration event as the Brazilian DNA which we know is not from the same event as the Botocudo.  I would very much like to see the Oceanic DNA appear in a migration path of people, not just in one place and then the other.  We need to connect the dots.

What this new information does is to rule out the possibility that there truly was only one wave of migration – one group of people who settled the Americas at one time.  More likely, at least until the land bridge submerged, is that there were multiple small groups that exited Beringia over the 8,000 or so years it was inhabitable.  Maybe one of those groups included people from Oceana.  Someplace, sometime, as unlikely as it seems, it happened.

The amazing thing is that it’s more than 10,000 miles from Australia to the Aleutian Islands, directly across the Pacific.  Early adventurers would have likely followed a coastal route to be sustainable, which would have been significantly longer.  The fact that they survived and sent their DNA on a long adventure from Australia to Alaska to South America – and it’s still present today is absolutely amazing.

Australia to Aleutians

We know we still have a lot to learn and this is the tip of a very exciting iceberg.  As more contemporary and ancient Native people have their full genomes sequenced, we’ll learn more answers.  The answer is in the DNA.  We just have to sequence enough of it and learn how to understand the message being delivered.

Botocudo Ancient Remains from Brazil

One thing you can always count on in the infant science of population genetics…  whatever you think you know, for sure, for a fact…well….you don’t.  So don’t say too much, too strongly or you’ll wind up having to decide if you’d like catsup with your crow!  Well, not literally, of course.  It’s an exciting adventure that we’re on together and it just keeps getting better and better.  And the times…they are a changin’.

We have some very interesting news to report.  Fortunately, or unfortunately – the news weaves a new, but extremely interesting, mystery.

Ancient Mitochondrial DNA

Back in 2013, a paper, Identification of Polynesian mtdNA haplogroups in remains of Botocudo Amerindians from Brazil, was published that identified both Native American and Polynesian haplogroups in a group of 14 skeletal remains of Botocudo Indians from Brazil whose remains arrived at a Museum in August of 1890 and who, the scientists felt, died in the second half of the 19th century.

Twelve of their mitochondrial haplogroups were the traditional Native haplogroup of C1.

However, two of the skulls carried Polynesian haplogroups, downstream of haplogroup B, specifically B4a1a1a and B4a1a1, that compare to contemporary individuals from Polynesian, Solomon Island and Fijian populations.  These haplotypes had not been found in Native people or previous remains.

Those haplogroups include what is known as the Polynesian motif and are found in Indonesian populations and also in Madagascar, according to the paper, but the time to the most common recent ancestor for that motif was calculated at 9,300 years plus or minus 2000 years.  This suggests that the motif arose after the Asian people who would become the Native Americans had already entered North and South America through Beringia, assuming there were no later migration waves.

The paper discusses several possible scenarios as to how a Polynesian haplotype found its way to central Brazil among a now extinct Native people. Of course, the two options are either pre-Columbian (pre-1500) contact or post-Columbian contact which would infer from the 1500s to current and suggests that the founders who carried the Polynesian motif were perhaps either slaves or sailors.

In the first half of the 1800s, the Botocudo Indians had been pacified and worked side by side with African slaves on plantations.

Beyond that, without full genome sequencing there was no more that could be determined from the remains at that time.  We know they carried a Polynesian motif, were found among Native American remains and at some point in history, intermingled with the Native people because of where they were found.  Initial contact could have been 9,000 years ago or 200.  There was no way to tell.  They did have some exact HVR1 and HVR2 matches, so they could have been “current,” but I’ve also seen HVR1 and HVR2 matches that reach back to a common ancestor thousands of years ago…so an HVR1/HVR2 match is nothing you can take to the bank, certainly not in this case.

Full Genome Sequencing and Y DNA

This week, one on my subscribers, Kalani, mentioned that Felix Immanuel had uploaded another two kits to GedMatch of ancient remains.  Those two kits are indeed two of the Botocudo remains – the two with the Polynesian mitochondrial motif which have now been fully sequenced.  A corresponding paper has been published as well, “Two ancient genomes reveal Polynesian ancestry among the indigenous Botocudos of Brazil” by Malaspinas et al with supplemental information here.

There are two revelations which are absolutely fascinating in this paper and citizen scientist’s subsequent work.

First, their Y haplogroups are C-P3092 and C-Z31878, both equivalent to C-B477 which identifies former haplogroup C1b2.  The Y haplogroups aren’t identified in the paper, but Felix identified them in the raw data files that are available (for those of you who are gluttons for punishment) at the google drive links in Felix’s article Two Ancient DNA from indigenous Botocudos of Brazil.

I’ve never seen haplogroup C1b2 as Native American, but I wanted to be sure I hadn’t missed a bus, so I contacted Ray Banks who is one of the administrators for the main haplogroup C project at Family Tree DNA and also is the coordinator for the haplogroup C portion of the ISOGG tree.

ISOGG y tree

You can see the position of C1b2, C-B477 in yellow on the ISOGG (2015) tree relative to the position of C-P39 in blue, the Native American SNP shown several branches below, both as branches of haplogroup C.

Ray maintains a much more descriptive tree of haplogroup C1 at this link and of C2 at this link.

Ray Banks C1 tree

The branch above is the Polynesian (B477) branch and below, the Native American (P39) branch of haplogroup C.

Ray Banks C2 treeIn addition to confirming the haplogroup that Felix identified, when Ray downloaded the BAM files and analyzed the contents, he found that both samples were also positive for M38 and M208, which moves them downstream two branches from C1b2 (B477).

Furthermore, one of the samples had a mutation at Z32295 which Ray has included as a new branch of the C tree, shown below.

Ray Banks Z32295

Ray indicated that the second sample had a “no read” at Z32295, so we don’t know if he carried this mutation.  Ray mentions that both men are negative for many of the B459 equivalents, which would move them down one more branch.  He also mentioned that about half of the Y DNA sites are missing, meaning they had no calls in the sequence read.  This is common in ancient DNA results.  It would be very interesting to have a Big Y or equivalent test on contemporary individuals with this haplogroup from the Pacific Island region.

Ray notes that all Pacific Islanders may be downstream of Z33295.

Not Admixed

The second interesting aspect of the genomic sequencing is that the remains did not show any evidence of admixture with European, Native American nor African individuals.  More than 97% of their genome fits exactly with the Polynesian motifs.  In other words, they appear to be first generation Polynesians.  They carry Polynesian mitochondrial, Y and autosomal (nuclear) DNA, exclusively.

Botocudo not admixed

In total, 25 Botocudo remains have been analyzed and of those, two have Polynesian ancestry and those two, BOT15 and BOT17, have exclusively Polynesian ancestry as indicated in the graphic above from the paper.

When did they live?  Accelerator mass spectrometry radiocarbon dating with marine correction gives us dates of 1479-1708 AD and 1730-1804 for specimen BOT15 and 1496-1842 for BOT17.

The paper goes on to discuss four possible scenarios for how this situation occurred and the pros and cons of each.

The Polynesian Peru Slave Trade

This occurred between 1862-1864 and can be ruled out because the dates for the skulls predate this trade period, significantly.

The Madagascar-Brazil Slave Trade

The researchers state that Madagascar is known to have been peopled by Southeast Asians and not by Polynesians.  Another factor excluding this option is that it’s known that the Malagasy ancestors admixed with African populations prior to the slave trade.  No such ancestry was detected in the samples, so these individuals were not brought as a result of the Madagascar-Brazil slave trade – contrary to what has been erroneously inferred and concluded.

Voyaging on European Ships as Crew, Passengers or StowAways

Trade on Euroamerican ships in the Pacific only began after 1760 AD and by 1760, Bot15 and Bot17 were already deceased with a probability of .92 and .81, respectively, making this scenario unlikely, but not entirely impossible.

Polynesian Voyaging

Polynesian ancestors originated from East Asia and migrated eastwards, interacting with New Guineans before colonizing the Pacific.  These people did colonize the Pacific, as unlikely as it seems, traveling thousands of miles, reaching New Zealand, Hawaii and Easter Island between 1200 and 1300 AD.  Clearly they did not reach Brazil in this timeframe, at least not as related to these skeletal remains, but that does not preclude a later voyage.

Of the four options, the first two appear to be firmly eliminated which leaves only the second two options.

One of the puzzling aspects of this analysis it the “pure” Polynesian genome, eliminating admixture which precludes earlier arrival.

The second puzzling aspect is how the individuals, and there were at least two, came to find themselves in Minas Gerais, Brazil, and why we have not found this type of DNA on the more likely western coastal areas of South America.

Minas Gerais Brazil

Regardless of how they arrived, they did, and now we know at least a little more of their story.

GedMatch

At GedMatch, it’s interesting to view the results of the one-to-one matching.

Both kits have several matches.  At 5cM and 500 SNPs, kit F999963 has 86 matches.  Of those, the mitochondrial haplogroup distribution is overwhelmingly haplogroup B, specifically B4a1a1 with a couple of interesting haplogroup Ms.

F999963 mito

Y haplogroups are primarily C2, C3 and O.   C3 and O are found exclusively in Asia – meaning they are not Native.

F999963 Y

Kit F999963 matches a couple of people at over 30cM with a generation match estimate just under 5 generations.  Clearly, this isn’t possible given that this person had died by about 1760, according to the paper, which is 255 years or about 8.5-10 generations ago, but it says something about the staying power of DNA segments and probably about endogamy and a very limited gene pool as well.  All matches over 15cM are shown below.

F999963 largest

Kit F999964 matches 97 people, many who are different people that kit F999963 matched.  So these ancient Polynesian people,  F999963 and F999964 don’t appear to be immediate relatives.

F999964 mito

Again, a lot of haplogroup B mitochondrial DNA, but less haplogroup C Y DNA and no haplogroup O individuals.

F999964 Y

Kit F999964 doesn’t match anyone quite as closely as kit F999963 did in terms of total cM, but the largest segment is 12cM, so the generational estimate is still at 4.6,  All matches over 15cM are shown below.

F999964 largest

Who are these individuals that these ancient kits are matching?  Many of these individuals know each other because they are of Hawaiian or Polynesian heritage and have already been working together.  Several of the Hawaiian folks are upwards of 80%, one at 94% and one believed to be 100% Hawaiian.  Some of these matches are to Maori, a Polynesian people from New Zealand, with one believed to be 100% Maori in addition to several admixed Maori.  So obviously, these ancient remains are matching contemporary people with Polynesian ancestry.

The Unasked Question

Sooner or later, we as a community are going to have to face the question of exactly what is Native or aboriginal.  In this case, because we do have the definitive autosomal full genome testing that eliminates admixture, these two individuals are clearly NOT Native.  Without full genomic testing, we would have never known.

But what if they had arrived 200 years earlier, around 1500 AD, one way or another, possibly on an early European ship, and had intermixed with the Native people for 10 generations?  What if they carried a Polynesian mitochondrial (or Y) DNA motif, but they were nearly entirely Native, or so much Native that the Polynesian could no longer be found autosomally?  Are they Native?  Is their mitochondrial or Y DNA now also considered to be Native?  Or is it still Polynesian?  Is it Polynesian if it’s found in the Cook Islands or on Hawaii and Native if found in South America?  How would we differentiate?

What if they arrived, not in 1500 AD, but about the year 500 AD, or 1000 BCE or 2000 BCE or 3000 BCE – after the Native people from Asia arrived but unquestionably before European contact?  Does that make a difference in how we classify their DNA?

We don’t have to answer this yet today, but something tells me that we will, sooner or later…and we might want to start pondering the question.

How Much Indian Do I Have in Me???

I can’t believe how often I receive this question.

Here’s today’s version from Patrick.

“My mother had 1/8 Indian and my grandmother on my father’s side was 3/4, and my grandfather on my father’s side had 2/3. How much would that make me?”

First, this question was about Native American ancestry, but it could just have easily have been about African, European, Asian, Jewish….fill in the blank.

Secondly, Patrick’s initial question is a math question, but the real question is how much of a particular ethnicity do you have on paper versus how much you have genetically.

How could they be different?

Lots of ways.

Oral history in families tends to get diluted and condensed over time.  For example, maybe grandmother wasn’t really 3/4th – because her ancestors were admixed and she (or her descendants) didn’t know it.  And how does one have 2/3, exactly, with 4 grandparents.  So, the story may not be the whole story.

For our example, we’re going to eliminate the 2/3 number, because it can’t be correct.  A grandparent would be 1/4th, a great grandparent, 1/8th.  In other words, ancestors fractions come in divisions of 4, or 2, but not 3 – because it takes 2 people in each generation.

So, you could have 3 of 4 ancestors who are native, which would make the person 3/4th, 2 of 4 which would make the person half, or 1 of 4 which would make the person one quarter, but you cannot have 1 of 3, 2 of 3 or 3 of 3, because you have 4 grandparents, not 3.

Math

First, let’s answer the math question.

Math is your friend.

There are three easy steps.

1. Divide Each Generation By Half to Current

Each ancestral generation is reduced by one half, because the DNA is diluted by half in each generation.

So, if Patrick’s mother is 1/8, Patrick is 1/16 on their mother’s side, because Patrick received half of her DNA.  With fractions, you can’t reduce the top number of 1 by one half so you double the bottom number.

If grandfather was 3/4, then father was 3/8 on that side and Patrick is 3/16th.

So, now, add the numbers for Patrick together.

2. Find the Common Denominator

The two numbers you need to add together from the above exmaple are 1/16 and 3/16.  This is easy because the denominator is already the same – 16.  But let’s say you also have a third number, just for purposes of example.  Let’s say that third number is 3/32.

How do you add 1/16, 3/16 and 3/32?

The denominator has to be the same.  If you look at the denominators, you’ll see that if you double the fractions with 16, they become fractions with 32 as their denominator.

So, for this example, 1/16 becomes 2/32, 3/16 becomes 6/32 and 3/32 remains the same.

3. Add the Top Numbers Together

Now just add the numerators, or the top numbers together.

2/32 + 6/32 + 3/32 = 11/32

That’s the answer.  In this example, our person, per their family history, is 11/32 Native or 34.38%.

Patrick, who originally asked the question is 1/16 + 3/16 which equals 4/16, which reduces to 1/4 (by dividing the same number, 4, into the top and bottom of the fraction), plus whatever amount that “2/3″ really is.  So, Patrick is more than one quarter, at least on paper.

Genetics

The next question is often, “how do I prove that?”  In terms of Native ancestry, the answer varies on the purpose – general interest, tribal identification or tribal membership, etc.  I’ve written about that in two articles, here and here.

You can take a DNA test from Family Tree DNA called Family Finder that provides you with percentages of ethnicity, including Native American, as well as a list of cousin matches. They also offer additional testing that may be relevant if you descend from the native person paternally (if you are a male) or matrilineally (for both sexes.)

On the diagram below, you can see the Y DNA in blue, inherited by males from their father and the mitochondrial or matrilineal DNA in red, always inherited from the mother.  While the Y and mitochondrial tests give you very specific information on two lines, the Family Finder test provides you with ethnicity information from all of your lines.  It just can’t tell you which line or lines the Native heritage came from.

adopted pedigree

Often, due to admixture in the Native population over the past several hundred years, since the Europeans “discovered” America, the amount of Native DNA is less than expected and sometimes is so far back and such a small amount that it doesn’t show at all.

An individual could well be considered a full tribal member, yet have less than half Native heritage.  Examples that come to mind are Mary Jemison, an adopted captive who was European, but considered a full tribal member, and Sequoyah, who invented the Cherokee alphabet.   Even the Cherokee Chief, Benge was at least half European, sporting red hair.  His mother was a member of the Cherokee tribe, so Benge was as well.  Cherokee Chief John Ross, born in 1790, was only one eighth Native.

So, the bottom line.  Enjoy your family history and heritage.  Document your family stories.  Understand that tribal membership was historically not a matter of percentages, at least not until the late 1800s and early 1900s.  Your ancestor either was or was not “Indian,” generally based on the tribal membership status of their mother.  There was no halfway and mixed didn’t matter.

DNA testing can confirm Native heritage.  It can also prove Native heritage in a variety of ways depending on how one descends from the Native ancestor(s), using Y and mitochondrial DNA.  Depending on whether Patrick is male or female, and how Patrick descends from his or her Native ancestors, the Y or mitochondrial DNA test can add a wealth of information to Patrick’s family history.

For some people, DNA testing is how one discovers that they have a Native ancestor.

So, how much Indian do you have in you, on paper and through DNA testing?

Cultural Footprints

I was recently corresponding with a descendant of Valentine Collins, one of the Melungeon families of mixed race found in and nearby Hawkins County, Tennessee in the 1800s.

Here’s what he had to say.

When I first started looking into my Collins’ family history, I realized very early this was going to be a real adventure. What I did was set up a system to look at different aspects of their lives/history. I call it ‘cultural footprints’. I have those foot prints broken down as:

  • Religion
  • The Table (food)
  • Music
  • Language

Most of the data I’ve mined are based on these four Cultural Footprints. But I would have to say Genetic Genealogy provided the biggest breakthroughs, the best tool by far.

Well, obviously I liked his commentary about genetic genealogy, which gives us the ability to connect and to prove, or disprove, connections.  But as I looked at his list, I thought about my own ancestors.  Those of you who follow my blog regularly know that I love to learn about the history during the time that my ancestors were living – what happened to and near them and how it affected them.  But his commentary made me wonder what I’ve been missing.

As I think back, one of the biggest and most useful clues to one of my ancestral lines was an accidental comment made by my mother about her grandmother. She mentioned, in passing, “that little white hat that she always wore.”  I almost didn’t say anything, but then I thought, “little white hat, that’s odd.”  So I asked and my mother said something like, “you know, those religious hats.”  I asked if she meant Amish or Mennonite, given the context of where they lived and she said, “yes, a hat like that.”  Then, when questioned further, it turns out that the family didn’t drive, even though cars were certainly utilized by then.  My mother never thought about it.  Turns out that the family was actually Brethren, also one of the pietist faiths similar to Amish and Mennonite, but that hint sent me in the right direction.

How could my mother have been unaware of something that important, well, important to me anyway?  Easy.  It was, ahem, not discussed in the family.  You see, it was somewhat of a scandal.

My mother’s father had married outside the Brethren religion, so was rather ostracized from the family for his choice to marry a Lutheran. Then the family became, horror of horrors, Methodist.  So, I would add clothing to my friend’s list of cultural footprints as well.  Sometimes, like in my case, dress will lead you to religion.  In the photo below, my mother’s grandmother is the female in the middle back row.  If you look carefully, you can see that both she and her mother are wearing a prayer cap.

I know the religion of many of my ancestors. Whatever their religious choice, it was extremely important to many.  I have 1709ers, Acadians, Brethren, Mennonites, Huguenots, fire and brimstone Baptists, Methodists and Presbyterians in my family line.  I always try to find their church and the church records if possible.  Some are quite interesting, like Joseph Bolton who was twice censured from the Baptist church in Hancock County, Tennessee.  Many of my ancestors made their life choices based on their faith.  In particular, the Huguenots, 1709ers, Brethren and Mennonites suffered greatly for their beliefs.  Conversely, some of my ancestors appear to never have set foot in a church.  I refer to them as the “free thinkers.”

Well, in one case, my ancestor was a bootlegger in the mountains of Kentucky. What the hey…every family has to have some color, and he was definitely colorful….and free thinking.

Most of us are a mixture of people, cultures and places. All of them are in us.  Their lives, culture, choices and  yes, their DNA, make us who we are.  If you have any doubt, just look at your autosomal ethnicity predictions.

Language of course is important, but more personally, local dialects that our ancestors may have spoken. In the US, every part of the country has their own way of speaking.

Here’s a YouTube video of a Louisiana Cajun accent. Many Acadians settled in that region after being forcibly removed from Nova Scotia in 1755.

Acadian-Cajun language, music and early homes in Louisiana

Here’s a wonderful video of Appalachian English. In my family, this is known as “hillbilly” and that is not considered a bad thing to be:)  In fact, we truthfully, all love Jeff Foxworthy, well, because he’s one of us.  I’m just sure if we could get him to DNA test, that we’d be related!

There are regional and cultural differences too.

Here’s a video about Lumbee English. The Lumbee are a Native American tribe found in North Carolina near the border with South Carolina.

Going further east in North Carolina, the Outer Banks has a very distinctive dialect.

What did your ancestor’s speech sound like?   What would it have sounded like in that time and place?

That, of course, leads to music. Sometimes music is the combination of speech and religion, with musical instruments added.  Sometimes it has nothing to do with religion, but moves us spiritually just the same.  Music is the voice of the soul.

Here’s Amazing Grace on the bagpipes. If you can get through this dry-eyed, well, then you’re not Scottish…just saying.  This connects me to my Scottish ancestors.  It was played at both my mother’s and my brother’s funerals.  Needless to say, I can’t get through it dry eyed!

Amazing Grace isn’t limited to bagpipes or musical instruments. The old “hardshell” Baptists didn’t utilize musical instruments, and still don’t, in their churches.  Listen to their beautiful voices, and the beautiful landscape of Kentucky.  This is the land, voices and religion of some of my people.

A hauntingly and sadly beautiful Negro Spiritual. Kleenex box warning.  This, too, is the music of my family.

Yeha – Noha – a Native American song by Sacred Spirit. One of my favorite music pieces.

Bluegrass gospel – Swing Low Sweet Chariot. Bet you can’t keep your foot from tapping!!!

Appalachian fiddle music. Speaks directly to my heart.  And my hands.  I just have to clap my hands.

Acadian music. This would be very familiar to my Acadian ancestors.

At this link, you can hear samples of Acadian folk songs by scrolling down and clicking on the track listing.

Moving a little closer in time. This is the official state song of Tennessee – one of my all-time favorites.  I can’t tell you how many times I’ve danced to this.  This just says “home” to me and I can feel my roots.

What kind of music did your ancestors enjoy? Did they play any musical instruments?  Can you find the music of the time and place in which they lived?  YouTube has a wide variety and the videos are an added benefit, bringing the reality of the life of our distant ancestors a little closer.

Now that you know what fed their souls, let’s look at what fed their bodies.  Along with regional speech and musical differences, the diet of our ancestors was unique and often quite different from ours of today.

On the Cumberland Gap Yahoo group, we often exchange and discuss regional recipes, especially around the holidays. Same on the Acadian rootsweb group.  Although this year we’ve been talking about deep fried turkeys.  Maybe in another couple hundred years that will be considered representative of our time.  Hopefully it’s not McDonalds!

The Smithsonian sponsors a website about Appalachian foods.  Let me share with you what I remember about my childhood.  We made do with what we had, whatever that was.  Some things were staples.  Like biscuits, with butter, or honey, or jam, or apple butter…whatever you had on hand that was in season.

biscuits

Chicken fried in bacon grease was for Sunday, or company, which usually came on Sunday.

We wasted nothing, ever, because you never knew when you might not have enough to eat. So, we ate leftovers until they were gone and we canned. Did we ever can.  Lord, we canned everything.  Mason jars in huge boiling kettles in the hottest part of summer.  Let’s just say that is not my favorite memory of growing up.  But green beans at Christmas time were just wonderful, and you couldn’t have those without canning in the August heat.

cans

Different areas have become known for certain types of cuisine. In North Carolina, they are known for their wood-fired BBQ.  In western North Carolina, they use a red, slightly sweet, tomato based BBQ sauce, but in eastern NC, they use a vinegar based BBQ sauce.  Want to start a fight?  Just say that the other one is better on the wrong side of the state:)

Creole cuisine is found in the south, near the Mississippi Delta region and is from a combination of French, Spanish and African heritage.

Jambalaya is a Louisiana adaptation of Spanish paella.

Soul food is the term for the foods emanating from slavery.  When I looked up soul food on wiki, I found the foods my family ate every day.  When I think of food that we didn’t eat, but that my African American cousins did eat, I think of chitlins.  Yes, I know I didn’t spell that correctly, but that’s how we spelled it. And the chitlins we had were flowered and fried too, not boiled.  Maybe that is a regional difference or an adaptation.

chitterlings

Another “out of Africa” food is sorghum, used to make a sweet substance similar to molasses, used on biscuits in our family. Sorghum is an African plant, often called Guinea Corn, and arrived with slaves in colonial days.

sorghum

Native American cuisine varies by where the tribe lived, and originally, they lived across all of North and South America. Originally, the Native people had the three sisters, corn, squash and beans.  Hominy is Native, as is grits, a southern staple today.  I’m drooling now…

grits

Today, however, one of the signature Native American dishes is FryBread. Fried and seriously unhealthy, the lines at powwows are longer for frybread and a derivative, Indian Tacos, than anything else.

frybread

In many places, the settlers, slaves and Native people assimilated and the food their descendants ate reflected all three cultures, like Brunswick Stew.  Even Brunswick Stew varies widely by location as do the origin stories.  Many foods seems to have evolved in areas occupied by European settlers, Native people and slaves, to reflect ingredients from all three groups.

Brunswick stew

That’s the case in my family, on my father’s side. We didn’t know any differently, or where that particular type of food originated.  However, sometimes by looking at the foods families ate, we can tell something of their origins.

In marginalized populations, and by that, in the US I mean mixed race or descendants of enslaved people, it’s often very difficult to use traditional genealogical records because they didn’t own land or leave other records. Many of them spent a lot of time trying to make themselves transparent and didn’t want to attract any attention.

Often, it’s the DNA that unlocks the doors to their heritage, and after making that discovery, we can then look the cultural footprints they left for us to follow.

I’m starving. I’m going to eat something unhealthy and listen to some wonderful music!  How about grits with butter and Indian tacos for lunch along with powwow music?  Oh yeahhhhhh…….

2014 Top Genetic Genealogy Happenings – A Baker’s Dozen +1

It’s that time again, to look over the year that has just passed and take stock of what has happened in the genetic genealogy world.  I wrote a review in both 2012 and 2013 as well.  Looking back, these momentous happenings seem quite “old hat” now.  For example, both www.GedMatch.com and www.DNAGedcom.com, once new, have become indispensable tools that we take for granted.  Please keep in mind that both of these tools (as well as others in the Tools section, below) depend on contributions, although GedMatch now has a tier 1 subscription offering for $10 per month as well.

So what was the big news in 2014?

Beyond the Tipping Point

Genetic genealogy has gone over the tipping point.  Genetic genealogy is now, unquestionably, mainstream and lots of people are taking part.  From the best I can figure, there are now approaching or have surpassed three million tests or test records, although certainly some of those are duplicates.

  • 500,000+ at 23andMe
  • 700,000+ at Ancestry
  • 700,000+ at Genographic

The organizations above represent “one-test” companies.  Family Tree DNA provides various kinds of genetic genealogy tests to the community and they have over 380,000 individuals with more than 700,000 test records.

In addition to the above mentioned mainstream firms, there are other companies that provide niche testing, often in addition to Family Tree DNA Y results.

In addition, there is what I would refer to as a secondary market for testing as well which certainly attracts people who are not necessarily genetic genealogists but who happen across their corporate information and decide the test looks interesting.  There is no way of knowing how many of those tests exist.

Additionally, there is still the Sorenson data base with Y and mtDNA tests which reportedly exceeded their 100,000 goal.

Spencer Wells spoke about the “viral spread threshold” in his talk in Houston at the International Genetic Genealogy Conference in October and terms 2013 as the year of infection.  I would certainly agree.

Autosomal Now the New Normal

Another change in the landscape is that now, autosomal DNA has become the “normal” test.  The big attraction to autosomal testing is that anyone can play and you get lots of matches.  Earlier in the year, one of my cousins was very disappointed in her brother’s Y DNA test because he only had a few matches, and couldn’t understand why anyone would test the Y instead of autosomal where you get lots and lots of matches.  Of course, she didn’t understand the difference in the tests or the goals of the tests – but I think as more and more people enter the playground – percentagewise – fewer and fewer do understand the differences.

Case in point is that someone contacted me about DNA and genealogy.  I asked them which tests they had taken and where and their answer was “the regular one.”  With a little more probing, I discovered that they took Ancestry’s autosomal test and had no clue there were any other types of tests available, what they could tell him about his ancestors or genetic history or that there were other vendors and pools to swim in as well.

A few years ago, we not only had to explain about DNA tests, but why the Y and mtDNA is important.  Today, we’ve come full circle in a sense – because now we don’t have to explain about DNA testing for genealogy in general but we still have to explain about those “unknown” tests, the Y and mtDNA.  One person recently asked me, “oh, are those new?”

Ancient DNA

This year has seen many ancient DNA specimens analyzed and sequenced at the full genomic level.

The year began with a paper titled, “When Populations Collide” which revealed that contemporary Europeans carry between 1-4% of Neanderthal DNA most often associated with hair and skin color, or keratin.  Africans, on the other hand, carry none or very little Neanderthal DNA.

http://dna-explained.com/2014/01/30/neanderthal-genome-further-defined-in-contemporary-eurasians/

A month later, a monumental paper was published that detailed the results of sequencing a 12,500 Clovis child, subsequently named Anzick or referred to as the Anzick Clovis child, in Montana.  That child is closely related to Native American people of today.

http://dna-explained.com/2014/02/13/clovis-people-are-native-americans-and-from-asia-not-europe/

In June, another paper emerged where the authors had analyzed 8000 year old bones from the Fertile Crescent that shed light on the Neolithic area before the expansion from the Fertile Crescent into Europe.  These would be the farmers that assimilated with or replaced the hunter-gatherers already living in Europe.

http://dna-explained.com/2014/06/09/dna-analysis-of-8000-year-old-bones-allows-peek-into-the-neolithic/

Svante Paabo is the scientist who first sequenced the Neanderthal genome.  Here is a neanderthal mangreat interview and speech.  This man is so interesting.  If you have not read his book, “Neanderthal Man, In Search of Lost Genomes,” I strongly recommend it.

http://dna-explained.com/2014/07/22/finding-your-inner-neanderthal-with-evolutionary-geneticist-svante-paabo/

In the fall, yet another paper was released that contained extremely interesting information about the peopling and migration of humans across Europe and Asia.  This was just before Michael Hammer’s presentation at the Family Tree DNA conference, so I covered the paper along with Michael’s information about European ancestral populations in one article.  The take away messages from this are two-fold.  First, there was a previously undefined “ghost population” called Ancient North Eurasian (ANE) that is found in the northern portion of Asia that contributed to both Asian populations, including those that would become the Native Americans and European populations as well.  Secondarily, the people we thought were in Europe early may not have been, based on the ancient DNA remains we have to date.  Of course, that may change when more ancient DNA is fully sequenced which seems to be happening at an ever-increasing rate.

Ancient DNA Available for Citizen Scientists

If I were to give a Citizen Scientist of the Year award, this year’s award would go unquestionably to Felix Chandrakumar for his work with the ancient genome files and making them accessible to the genetic genealogy world.  Felix obtained the full genome files from the scientists involved in full genome analysis of ancient remains, reduced the files to the SNPs utilized by the autosomal testing companies in the genetic genealogy community, and has made them available at GedMatch.

http://dna-explained.com/2014/09/22/utilizing-ancient-dna-at-gedmatch/

If this topic is of interest to you, I encourage you to visit his blog and read his many posts over the past several months.

https://plus.google.com/+FelixChandrakumar/posts

The availability of these ancient results set off a sea of comparisons.  Many people with Native heritage matched Anzick’s file at some level, and many who are heavily Native American, particularly from Central and South America where there is less admixture match Anzick at what would statistically be considered within a genealogical timeframe.  Clearly, this isn’t possible, but it does speak to how endogamous populations affect DNA, even across thousands of years.

http://dna-explained.com/2014/09/23/analyzing-the-native-american-clovis-anzick-ancient-results/

Because Anzick is matching so heavily with the Mexican, Central and South American populations, it gives us the opportunity to extract mitochondrial DNA haplogroups from the matches that either are or may be Native, if they have not been recorded before.

http://dna-explained.com/2014/09/23/analyzing-the-native-american-clovis-anzick-ancient-results/

Needless to say, the matches of these ancient kits with contemporary people has left many people questioning how to interpret the results.  The answer is that we don’t really know yet, but there is a lot of study as well as speculation occurring.  In the citizen science community, this is how forward progress is made…eventually.

Felix has prepared a list of kits that he has processed, along with their GedMatch numbers and other relevant information, like gender, haplogroup(s), age and location of sample.

http://www.y-str.org/p/ancient-dna.html

Furthermore, in a collaborative effort with Family Tree DNA, Felix formed an Ancient DNA project and uploaded the ancient autosomal files.  This is the first time that consumers can match with Ancient kits within the vendor’s data bases.

https://www.familytreedna.com/public/Ancient_DNA

Recently, GedMatch added a composite Archaic DNA Match comparison tool where your kit number is compared against all of the ancient DNA kits available.  The output is a heat map showing which samples you match most closely.

Indeed, it has been a banner year for ancient DNA and making additional discoveries about DNA and our ancestors.  Thank you Felix.

Haplogroup Definition

That SNP tsunami that we discussed last year…well, it made landfall this year and it has been storming all year long…in a good way.  At least, ultimately, it will be a good thing.  If you asked the haplogroup administrators today about that, they would probably be too tired to answer – as they’ve been quite overwhelmed with results.

The Big Y testing has been fantastically successful.  This is not from a Family Tree DNA perspective, but from a genetic genealogy perspective.  Branches have been being added to and sawed off of the haplotree on a daily basis.  This forced the renaming of the haplogroups from the old traditional R1b1a2 to R-M269 in 2012.  While there was some whimpering then, it would be nothing like the outright wailing now that would be occurring as haplogroup named reached 20 or so digits.

Alice Fairhurst discussed the SNP tsunami at the DNA Conference in Houston in October and I’m sure that the pace hasn’t slowed any between now and then.  According to Alice, in early 2014, there were 4115 individual SNPs on the ISOGG Tree, and as of the conference, there were 14,238 SNPs, with the 2014 addition total at that time standing at 10,213.  That is over 1000 per month or about 35 per day, every day.

Yes, indeed, that is the definition of a tsunami.  Every one of those additions requires one of a number of volunteers, generally haplogroup project administrators to evaluate the various Big Y results, the SNPs and novel variants included, where they need to be inserted in the tree and if branches need to be rearranged.  In some cases, naming request for previously unknown SNPs also need to be submitted.  This is all done behind the scenes and it’s not trivial.

The project I’m closest to is the R1b L-21 project because my Estes males fall into that group.  We’ve tested several, and I’ll be writing an article as soon as the final test is back.

The tree has grown unbelievably in this past year just within the L21 group.  This project includes over 700 individuals who have taken the Big Y test and shared their results which has defined about 440 branches of the L21 tree.  Currently there are almost 800 kits available if you count the ones on order and the 20 or so from another vendor.

Here is the L21 tree in January of 2014

L21 Jan 2014 crop

Compare this with today’s tree, below.

L21 dec 2014

Michael Walsh, Richard Stevens, David Stedman need to be commended for their incredible work in the R-L21 project.  Other administrators are doing equivalent work in other haplogroup projects as well.  I big thank you to everyone.  We’d be lost without you!

One of the results of this onslaught of information is that there have been fewer and fewer academic papers about haplogroups in the past few years.  In essence, by the time a paper can make it through the peer review cycle and into publication, the data in the paper is often already outdated relative to the Y chromosome.  Recently a new paper was released about haplogroup C3*.  While the data is quite valid, the authors didn’t utilize the new SNP naming nomenclature.  Before writing about the topic, I had to translate into SNPese.  Fortunately, C3* has been relatively stable.

10th Annual International Conference on Genetic Genealogy

The Family Tree DNA International Conference on Genetic Genealogy for project administrators is always wonderful, but this year was special because it was the 10th annual.  And yes, it was my 10th year attending as well.  In all these years, I had never had a photo with both Max and Bennett.  Everyone is always so busy at the conferences.  Getting any 3 people, especially those two, in the same place at the same time takes something just short of a miracle.

roberta, max and bennett

Ten years ago, it was the first genetic genealogy conference ever held, and was the only place to obtain genetic genealogy education outside of the rootsweb genealogy DNA list, which is still in existence today.  Family Tree DNA always has a nice blend of sessions.  I always particularly appreciate the scientific sessions because those topics generally aren’t covered elsewhere.

I thank Family Tree DNA for sponsoring all 10 conferences and continuing the tradition.  It’s really an amazing feat when you consider that 15 years ago, this industry didn’t exist at all and wouldn’t exist today if not for Max and Bennett.

Education

Two educational venues offered classes for genetic genealogists and have made their presentations available either for free or very reasonably.  One of the problems with genetic genealogy is that the field is so fast moving that last year’s session, unless it’s the very basics, is probably out of date today.  That’s the good news and the bad news.

Ancestor Reconstruction – Raising the Dead

This seems to be the year that genetic genealogists are beginning to reconstruct their ancestors (on paper, not in the flesh) based on the DNA that the ancestors passed on to various descendants.  Those segments are “gathered up” and reassembled in a virtual ancestor.

I utilized Kitty Cooper’s tool to do just that.

http://dna-explained.com/2014/10/03/ancestor-reconstruction/

Speaking of tools, we have some new tools that have been introduced this year as well.

Genome Mate is a desktop tool used to organize data collected by researching DNA comparsions and aids in identifying common ancestors.  I have not used this tool, but there are others who are quite satisfied.  It does require Microsoft Silverlight be installed on your desktop.

The Autosomal DNA Segment Analyzer is available through www.dnagedcom.com and is a tool that I have used and found very helpful.  It assists you by visually grouping your matches, by chromosome, and who you match in common with.

adsa cluster 1

Charting Companion from Progeny Software, another tool I use, allows you to colorize and print or create pdf files that includes X chromosome groupings.  This greatly facilitates seeing how the X is passed through your ancestors to you and your parents.

WikiTree is a free resource for genealogists to be able to sort through relationships involving pedigree charts.  In November, they announced Relationship Finder.

Probably the best example I can show of how WikiTree has utilized DNA is using the results of King Richard III.

By clicking on the DNA icon, you see the following:

wiki richard 2

And then Richard’s Y, mitochondrial and X chromosome paths.

wiki richard 3

Since Richard had no descendants, to see how descendants work, click on his mother, Cecily of York’s DNA descendants and you’re shown up to 10 generations.

wiki richard 4

While this isn’t terribly useful for Cecily of York who lived and died in the 1400s, it would be incredibly useful for finding mitochondrial descendants of my ancestor born in 1802 in Virginia.  I’d love to prove she is the daughter of a specific set of parents by comparing her DNA with that of a proven daughter of those parents!  Maybe I’ll see if I can find her parents at WikiTree.

Kitty Cooper’s blog talks about additional tools.  I have used Kitty’s Chromosome mapping tools as discussed in ancestor reconstruction.

Felix Chandrakumar has created a number of fun tools as well.  Take a look.  I have not used most of these tools, but there are several I’ll be playing with shortly.

Exits and Entrances

With very little fanfare, deCODEme discontinued their consumer testing and reminded people to download their date before year end.

http://dna-explained.com/2014/09/30/decodeme-consumer-tests-discontinued/

I find this unfortunate because at one time, deCODEme seemed like a company full of promise for genetic genealogy.  They failed to take the rope and run.

On a sad note, Lucas Martin who founded DNA Tribes unexpectedly passed away in the fall.  DNA Tribes has been a long-time player in the ethnicity field of genetic genealogy.  I have often wondered if Lucas Martin was a pseudonym, as very little information about Lucas was available, even from Lucas himself.  Neither did I find an obituary.  Regardless, it’s sad to see someone with whom the community has worked for years pass away.  The website says that they expect to resume offering services in January 2015. I would be cautious about ordering until the structure of the new company is understood.

http://www.dnatribes.com/

In the last month, a new offering has become available that may be trying to piggyback on the name and feel of DNA Tribes, but I’m very hesitant to provide a link until it can be determined if this is legitimate or bogus.  If it’s legitimate, I’ll be writing about it in the future.

However, the big news exit was Ancestry’s exit from the Y and mtDNA testing arena.  We suspected this would happen when they stopped selling kits, but we NEVER expected that they would destroy the existing data bases, especially since they maintain the Sorenson data base as part of their agreement when they obtained the Sorenson data.

http://dna-explained.com/2014/10/02/ancestry-destroys-irreplaceable-dna-database/

The community is still hopeful that Ancestry may reverse that decision.

Ancestry – The Chromosome Browser War and DNA Circles

There has been an ongoing battle between Ancestry and the more seasoned or “hard-core” genetic genealogists for some time – actually for a long time.

The current and most long-standing issue is the lack of a chromosome browser, or any similar tools, that will allow genealogists to actually compare and confirm that their DNA match is genuine.  Ancestry maintains that we don’t need it, wouldn’t know how to use it, and that they have privacy concerns.

Other than their sessions and presentations, they had remained very quiet about this and not addressed it to the community as a whole, simply saying that they were building something better, a better mousetrap.

In the fall, Ancestry invited a small group of bloggers and educators to visit with them in an all-day meeting, which came to be called DNA Day.

http://dna-explained.com/2014/10/08/dna-day-with-ancestry/

In retrospect, I think that Ancestry perceived that they were going to have a huge public relations issue on their hands when they introduced their new feature called DNA Circles and in the process, people would lose approximately 80% of their current matches.  I think they were hopeful that if they could educate, or convince us, of the utility of their new phasing techniques and resulting DNA Circles feature that it would ease the pain of people’s loss in matches.

I am grateful that they reached out to the community.  Some very useful dialogue did occur between all participants.  However, to date, nothing more has happened nor have we received any additional updates after the release of Circles.

Time will tell.

http://dna-explained.com/2014/11/18/in-anticipation-of-ancestrys-better-mousetrap/

http://dna-explained.com/2014/11/19/ancestrys-better-mousetrap-dna-circles/

DNA Circles 12-29-2014

DNA Circles, while interesting and somewhat useful, is certainly NOT a replacement for a chromosome browser, nor is it a better mousetrap.

http://dna-explained.com/2014/11/30/chromosome-browser-war/

In fact, the first thing you have to do when you find a DNA Circle that you have not verified utilizing raw data and/or chromosome browser tools from either 23andMe, Family Tree DNA or Gedmatch, is to talk your matches into transferring their DNA to Family Tree DNA or download to Gedmatch, or both.

http://dna-explained.com/2014/11/27/sarah-hickerson-c1752-lost-ancestor-found-52-ancestors-48/

I might add that the great irony of finding the Hickerson DNA Circle that led me to confirm that ancestry utilizing both Family Tree DNA and GedMatch is that today, when I checked at Ancestry, the Hickerson DNA Circle is no longer listed.  So, I guess I’ve been somehow pruned from the circle.  I wonder if that is the same as being voted off of the island.  So, word to the wise…check your circles often…they change and not always in the upwards direction.

The Seamy Side – Lies, Snake Oil Salesmen and Bullys

Unfortunately a seamy side, an underbelly that’s rather ugly has developed in and around the genetic genealogy industry.  I guess this was to be expected with the rapid acceptance and increasing popularity of DNA testing, but it’s still very unfortunate.

Some of this I expected, but I didn’t expect it to be so…well…blatant.

I don’t watch late night TV, but I’m sure there are now DNA diets and DNA dating and just about anything else that could be sold with the allure of DNA attached to the title.

I googled to see if this was true, and it is, although I’m not about to click on any of those links.

google dna dating

google dna diet

Unfortunately, within the ever-growing genetic genealogy community a rather large rift has developed over the past couple of years.  Obviously everyone can’t get along, but this goes beyond that.  When someone disagrees, a group actively “stalks” the person, trying to cost them their employment, saying hate filled and untrue things and even going so far as to create a Facebook page titled “Against<personname>.”  That page has now been removed, but the fact that a group in the community found it acceptable to create something like that, and their friends joined, is remarkable, to say the least.  That was accompanied by death threats.

Bullying behavior like this does not make others feel particularly safe in expressing their opinions either and is not conducive to free and open discussion. As one of the law enforcement officers said, relative to the events, “This is not about genealogy.  I don’t know what it is about, yet, probably money, but it’s not about genealogy.”

Another phenomenon is that DNA is now a hot topic and is obviously “selling.”  Just this week, this report was published, and it is, as best we can tell, entirely untrue.

http://worldnewsdailyreport.com/usa-archaeologists-discover-remains-of-first-british-settlers-in-north-america/

There were several tip offs, like the city (Lanford) and county (Laurens County) is not in the state where it is attributed (it’s in SC not NC), and the name of the institution is incorrect (Johns Hopkins, not John Hopkins).  Additionally, if you google the name of the magazine, you’ll see that they specialize in tabloid “faux reporting.”  It also reads a lot like the King Richard genuine press release.

http://urbanlegends.about.com/od/Fake-News/tp/A-Guide-to-Fake-News-Websites.01.htm

Earlier this year, there was a bogus institutional site created as well.

On one of the DNA forums that I frequent, people often post links to articles they find that are relevant to DNA.  There was an interesting article, which has now been removed, correlating DNA results with latitude and altitude.  I thought to myself, I’ve never heard of that…how interesting.   Here’s part of what the article said:

Researchers at Aberdeen College’s Havering Centre for Genetic Research have discovered an important connection between our DNA and where our ancestors used to live.

Tiny sequence variations in the human genome sometimes called Single Nucleotide Polymorphisms (SNPs) occur with varying frequency in our DNA.  These have been studied for decades to understand the major migrations of large human populations.  Now Aberdeen College’s Dr. Miko Laerton and a team of scientists have developed pioneering research that shows that these differences in our DNA also reveal a detailed map of where our own ancestors lived going back thousands of years.

Dr. Laerton explains:  “Certain DNA sequence variations have always been important signposts in our understanding of human evolution because their ages can be estimated.  We’ve known for years that they occur most frequently in certain regions [of DNA], and that some alleles are more common to certain geographic or ethnic groups, but we have never fully understood the underlying reasons.  What our team found is that the variations in an individual’s DNA correlate with the latitudes and altitudes where their ancestors were living at the time that those genetic variations occurred.  We’re still working towards a complete understanding, but the knowledge that sequence variations are connected to latitude and altitude is a huge breakthrough by itself because those are enough to pinpoint where our ancestors lived at critical moments in history.”

The story goes on, but at the bottom, the traditional link to the publication journal is found.

The full study by Dr. Laerton and her team was published in the September issue of the Journal of Genetic Science.

I thought to myself, that’s odd, I’ve never heard of any of these people or this journal, and then I clicked to find this.

Aberdeen College bogus site

About that time, Debbie Kennett, DNA watchdog of the UK, posted this:

April Fools Day appears to have arrived early! There is no such institution as Aberdeen College founded in 1394. The University of Aberdeen in Scotland was founded in 1495 and is divided into three colleges: http://www.abdn.ac.uk/about/colleges-schools-institutes/colleges-53.php

The picture on the masthead of the “Aberdeen College” website looks very much like a photo of Aberdeen University. This fake news item seems to be the only live page on the Aberdeen College website. If you click on any other links, including the link to the so-called “Journal of Genetic Science”, you get a message that the website is experienced “unusually high traffic”. There appears to be no such journal anyway.

We also realized that Dr. Laerton, reversed, is “not real.”

I still have no idea why someone would invest the time and effort into the fake website emulating the University of Aberdeen, but I’m absolutely positive that their motives were not beneficial to any of us.

What is the take-away of all of this?  Be aware, very aware, skeptical and vigilant.  Stick with the mainstream vendors unless you realize you’re experimenting.

King Richard

King Richard III

The much anticipated and long-awaited DNA results on the remains of King Richard III became available with a very unexpected twist.  While the science team feels that they have positively identified the remains as those of Richard, the Y DNA of Richard and another group of men supposed to have been descended from a common ancestor with Richard carry DNA that does not match.

More Alike than Different

One of the life lessons that genetic genealogy has held for me is that we are more closely related that we ever knew, to more people than we ever expected, and we are far more alike than different.  A recent paper recently published by 23andMe scientists documents that people’s ethnicity reflect the historic events that took place in the part of the country where their ancestors lived, such as slavery, the Trail of Tears and immigration from various worldwide locations.

23andMe European African map

From the 23andMe blog:

The study leverages samples of unprecedented size and precise estimates of ancestry to reveal the rate of ancestry mixing among American populations, and where it has occurred geographically:

  • All three groups – African Americans, European Americans and Latinos – have ancestry from Africa, Europe and the Americas.
  • Approximately 3.5 percent of European Americans have 1 percent or more African ancestry. Many of these European Americans who describe themselves as “white” may be unaware of their African ancestry since the African ancestor may be 5-10 generations in the past.
  • European Americans with African ancestry are found at much higher frequencies in southern states than in other parts of the US.

The ancestry proportions point to the different regional impacts of slavery, immigration, migration and colonization within the United States:

  • The highest levels of African ancestry among self-reported African Americans are found in southern states, especially South Carolina and Georgia.
  • One in every 20 African Americans carries Native American ancestry.
  • More than 14 percent of African Americans from Oklahoma carry at least 2 percent Native American ancestry, likely reflecting the Trail of Tears migration following the Indian Removal Act of 1830.
  • Among self-reported Latinos in the US, those from states in the southwest, especially from states bordering Mexico, have the highest levels of Native American ancestry.

2015

So what does 2015 hold? I don’t know, but I can’t wait to find out. Hopefully, it holds more ancestors, whether discovered through plain old paper research, cousin DNA testing or virtually raised from the dead!

What would my wish list look like?

  • More ancient genomes sequenced, including ones from North and South America.
  • Ancestor reconstruction on a large scale.
  • The haplotree becoming fleshed out and stable.
  • Big Y sequencing combined with STR panels for enhanced genealogical research.
  • Improved ethnicity reporting.
  • Mitochondrial DNA search by ancestor for descendants who have tested.
  • More tools, always more tools….
  • More time to use the tools!

Here’s wishing you an ancestor filled 2015!

 

The Fur Family – 52 Ancestors #51

I’ve been behind all week long.  My 52 Ancestors article for this week isn’t written and it’s Sunday, the day I always post my article.  It’s not even started, and here is why….

Me and Ellie

Her name is Ellie and she is about 11 weeks old.  I never intended to have Ellie, and truth told, I’m “only” babysitting.

My daughter rescued Ellie on Wednesday evening and brought her straight to my house so we could assess the situation.  My kids grew up rescuing animals.  For years we were volunteers for the local Humane Society and a foster home for literally hundreds of animals, one or two (or a litter) at a time.  And yes, it goes without saying that a few of the most needy stayed.  We had quite the group of misfits that we loved dearly.

When my former husband had a massive stroke in the 1990s, my volunteer and foster days ended.  By then, my kids had already spent their childhood on countless rescue runs and endless days and nights of bottle feeding orphaned animals.  So, the “damage” was done and, I’m proud to say, my daughter seems to be a chip off of the old block!

Then why doesn’t said daughter have the puppy?  Great question.  Said daughter and her husband had plans to visit husband’s family, out of town, for Christmas.  Said daughter could not board this puppy who had never seen a vet in her life, and therefore had no shots, and therefore, the puppy got to come and stay with Grandma.

Suffice it to say that babysitting an 11 or 12 week old puppy who has had no structure to her life is much like babysitting an 18 month old child.  They are fully mobile and into everything, except the child wears diapers and, hopefully, doesn’t chew the furniture.  Still, as puppies go, Ellie is pretty good and smart as a whip.

Case in point – she already has Grandma and Grandpa pretty well trained.

Ellie and toys

Grandpa bought her several toys and treats and Grandma made her a puppy quilt.  She loves to lay on things and thankfully, doesn’t chew those…only furniture.

Ellie and quilt

Now, Ellie had never had a toy before so she is an EXTREMELY happy puppy and is very quickly learning what is hers and what is not.

What kind of dog is Ellie?  We don’t know.

When we adopted our animals in the past, we never knew what they were – just mutts or “looked like” a Beagle.

Today, however, you can DNA test your dog to find out what kind they are.  Ellie is supposed to be a boxer mix – and she loved, and I mean LOVED her bath, so maybe some water dog like lab too.  She also has the webbed feet.

I checked into the dog DNA testing by Wisdom, and I discovered that the reviews of doggie DNA testing are pretty much all over the map, just like the ethnicity testing of people.  In fact, surprisingly similar.  I would only have done this out of curiosity anyway, because truthfully, it doesn’t matter what Ellie is…she is a puppy who was in need and that was all that mattered.

And given how many dog chew toys she has enjoyed these past several days, I’m thinking that $79 is better spent on chew toys than on a DNA test!

Those Who Came Before

The last of our herd of misfit dogs crossed over the rainbow bridge just over a year ago now.  While I certainly miss having a dog (or two or three) on one hand, on the other, I certainly don’t miss certain aspects…like accompanying the dog outside.  It’s winter and there is snow.

And, I might add, the cats….oh, the cats….they are requesting an attorney.  They aren’t frightened, just very very VERY unhappy right now.

Ellie, on the other hand, keeps taking her toys and offering them to the cats and play bowing, inviting them in dog language to play.  The cats are having NONE of that and are insulted at the very idea.

Having Ellie here for a few days has brought back such bittersweet memories.

In many cases, we are actually closer to our fur family than to our human family.  I mean, think about it, your dog loves you unconditionally.  You are their life.

I slept with my dogs and now, the cats – at least the ones who deign to grace us with their presence.  I don’t sleep with most of my family.

But then, our fur family leaves us, all too soon.  Even if they come to us as puppies or kittens, their life expectancy is much shorter than ours.  And they leave huge, HUGE, holes in our heart.  I’ve long said that if there aren’t pets in Heaven, I simply don’t want to go.

My first official pet wasn’t even mine.  My brother had a dog named Rex.  He was a mutt of sorts, a reverse looking Dalmation that was black with white spots.  Being a toddler, I just loved Rex, and let’s just say that Rex did not share the same level of enthusiasm for me.  Rex would immobilize me by sitting on me.

Rex and Me

Then there was Timmy.

Me and Timmy crop

Timmy was a Chihuahua that my father had rescued someplace.  Timmy went just about everyplace with him.  I loved Timmy and claimed him for my own of course.  My parents were no longer married by this time, as my father was a bit of a “womanizer,” to put it mildly.

One time, I remember, in the middle of the night, the phone rang, followed by a short conversation.  Mom got me out of bed and told me to get dressed.  Now this was a GREAT adventure – on a secret mission – in the middle of the night.

Off we went.  I’m sure my mother was trying to figure out what to say to me and how.

It seems that my father had gotten himself arrested for driving under the influence.  He had fallen off the wagon, again, and gotten caught.  My Mom was not enamored with my father at this point in her life, especially after she found out about his “other family”…so why…you’re wondering…did she get up in the middle of the night?

Timmy…she went to get Timmy.  Timmy, you see, was in jail too and the jail he was about to go too would likely have been a death sentence.

So, much to my father’s chagrin, Mom bailed Timmy out and left my Dad sitting there in all of his much-deserved misery.  And rest assured, my mother was NOT a happy camper.

My first official pet, when I was about 10 or so, was Freckles.  Freckles was a fantail goldfish with freckles.  I begged and begged my mother to allow me to have a pet, but she said it was unfair to leave a pet in the house all day by themselves when she worked and I was in school.  So, a goldfish it was.  I loved Freckles and changed his water in his bowl faithfully every Saturday morning.  Freckles even let me pet him with my finger when I fed him.

When Freckles died, I had a funeral and buried Freckles in the garden. I’m sure the neighbors thought surely I had lost my mind, on my knees in the garden, digging a hole and crying.  They probably “had a word” with my mother.

My mother had a boyfriend, or a “friend” as they were called then, whose mother died in about 1968 or 1969, in the fall.  By then I was 12 or 13.  After his mother passed away, the three of us went to her house in the country to begin going through her things.  When we arrived, a small white kitten appeared out of noplace, obviously thin and in need.  It was late fall, and very cold – near Christmas.

We found something in his mother’s house to feed the famished kitten.  I knew, we all knew, that if we drove away, it was a death sentence for this creature.   I picked her up, held her frail shivering body close for warmth, and looked at mother.  There were no words of request, but in my heart, I was ready to take my first stand against my mother if I had to.  I was not leaving without that kitten.  I simply couldn’t.  My mother looked at me and Snowball, sighed, and said, “I can’t fight both of you.”  I didn’t realize until later that my mother’s real concern was money – vet bills and such.  Mother certainly didn’t want to leave Snowball either.

Snowball 1970 crop

Snowball 1970 - 2 crop

Snowball, shortened to Snowy, was a cherished part of our family for the next 18 years or so.  Well we cherished her.  She was pretty disdainful of us – unless she needed someone to escape to when taken to the vet.  Then she suddenly knew us.

She survived being an indoor-outdoor cat, a move to the farm when my Mom married (a different friend) a few years later and being integrated into a family with a dog.

I was fully an adult when Snowy passed over the rainbow bridge.  I don’t think she ever liked me as much as she did that day when she was rescued.  Cats are like that!  But she was my special friend and I surely loved her.

In 1970, I lived overseas for awhile.  When I came home, I ran into the house to see Snowball.  She ran right over to me, rubbed around my legs three times, chirped hello…and then stalked off, mad that I had been gone in the first place.  And that was as good as it ever got!

Living on the farm, there was always a dog or cat that needed help of some sort.  In addition, Dad was always bringing some other kind of creature in need to the house too.  A pig, something.  We helped them all as best we could.

After I began my own family, I rescued another dog who had been dumped.  This one had been hit, either before or after.  I opened my car door to her on the side of the road and she jumped in. She was one of the best friends one could ever have.  She was extremely close to me.  I don’t think dogs ever forget a kindness.

And tolerant, unbelievable what that dog tolerated.  The night she unexpectedly died, I was crying so hard when I called my mother that she thought either my son or my husband had died and she was trying to figure out where she needed to go – hospital, house, morgue, etc.

Thanks to my step-Dad, I began rescuing creatures in need as a part of life.  I really didn’t think anything about it.

One time, I had somehow obtained a litter of kittens without a mother that had to be bottle fed.  I worked in town which was a half hour drive each way, so I couldn’t come home to feed them mid-day.  Dad did the best he could.  One day, for some reason, I came home early to walk into the kitchen to see my father’s huge gnarly hands holding a so-fragile kitten with its tiny bottle.  It would have been so much easier for him just to dispose of the kittens, but the man had a heart of gold and would never have done that unless they were suffering.  That scene is forever burned in my mind when I think of why I love that man.

Time moved on and so did I.  College years and grad school and moving across the country.  Cats move easily, thankfully, and adapt pretty well to just about anyplace where they have food and a litter box.  They might not be happy, but then cats would never admit they were happy anyway!

After grad school, I became involved with the local Humane Society as part of their rescue group and as a foster home as well for orphaned and injured animals.

We were blessed with so many creatures that graced our lives – some for a short while as we found them their forever home and some, forever.  We surely made a difference in their lives, but they made a difference in ours too.

I’d be remiss here if I didn’t mention two incredible Siamese cats that graced our lives, each living about 20 years and spanning about 40 years between them, and both taking care of all of the other creatures in need that we drug in over the years.  The older cat even took care of an orphan goat and puppies, although she thought they were FILTHY and needed constant cat scrubbing.

Casey Jones would capture and hide the orphans when they cried, as it upset her.  And they all cried.  We had to go and find where she had hidden them.  She would be frantically washing them and trying to feed them.  We simply were deficient surrogate cat mothers.  Casey helped quilt too.  Casey, rescued from the pound because she refused to use a filthy litter box, took care of the older cat when she was too old and feeble to take care of herself.  She won my heart right there.  Casey tried to comfort me when the older cat passed within days of my sister’s death.  I still miss Casey.

Casey Jones

In the 1990s, we wound up with 4 misfit dogs, 3 Beagles and a Dalmatian who thought she was a Beagle.  Each of these dogs came from a terrible situation and all of them were not adoptable for various reasons, so they became ours.  All 4 were obedience trained to both voice and hand signals, and believe it or not, I could take all 4 of them out in the yard, at once, off leash, and they were perfectly well behaved.  I know that is particularly difficult to believe, especially with Beagles.

Missy, the Dalmatian, went deaf with age but we never knew it until we realized that she was only responding to the hand signals.

While we think of these dogs as rescue dogs, they also contributed greatly to the family in so many ways.

I was home alone with the kids one time, and a man I didn’t know knocked on the front screen door.  It was summertime, and that door wasn’t locked.  I was right inside in the kitchen.  I heard Missy growl in the living room.  She was watching him intently.  She had never growled at anyone.  Then he tried to open the door.  I say tried, because that dog was up and at the door in split second, all teeth and fangs.  Suddenly, he was trying to push the door closed to protect himself from 50 pounds of snarling dog.  Not to be defeated, Missy then tried to go through the screen.  I yelled at him….”You’d better run because I don’t know how long I can hold this dog and she’ll kill you.”  He ran like the wind and we never saw him again.  The police told us that there was a “gang” of people doing “kitchen robberies” although I shudder to think what he would have done if he was willing to walk right in with me standing there.  My door was forever locked after that.  Missy certainly earned her home.  Missy would also smile on command and loved corn on the cob.  She was also the local volunteer Fire Department mascot in parades, riding in the fire truck.

Missy

In the 1990s, I unexpectedly became single again and never expected to remarry, or even date, for that matter.  Let’s just say it would take a special person to understand that no, I cannot drive by anything and not help it, among other things.  I had known Jim for years in a professional and then a friendship setting, but I never really expected anything more.  Jim became a regular visitor and then, one day I walked in to find this.  I knew this relationship had possibilities.

Jim and dogs

Of course, I couldn’t believe he just let Bagel the Beagle lay ON the coffee table….and we had to have a chat about that.  Bagel ruled whatever part of the house you let her rule.

Which of course, brings us to Bagel the Beagle.  Some of the fur family leaves their pawprints indelibly on our hearts and Bagel was one of my very special friends.  She was a stray at the pound and her days were up, literally.  The gal who worked at the pound called me, at work, and told me that she had a pregnant Beagle and either she was to be sold to the research buyer that day, or euthanized – both a death sentence.  She begged me to take her, telling me how sweet this dog was and that if she were to take her home herself, “my ole man will beat me.”  How could I say no?

I made her a deal.  I would take the dog, but I couldn’t leave work and she would have to drop her at the vet for me and pick up the adoption money at the vet.  Then I called my vet and asked them to give her the money for the dog.  It goes without saying I knew the vet very well.  I think there is a wing of their building named after me.

By the time I got to the vet, after work, I had a pregnant beagle who my daughter named Bagel because she was so very pregnant that she looked like a Beagle in a bagel.  Her name didn’t matter, because she was only a foster dog and would get a forever home after the puppies were born and weaned.  Right????

Wrong.

Bagel the Beagle became ours.  She gave birth that night, cuddled up with my daughter in her sleeping bag on the floor.  My daughter was “camping” by the dog’s bed so she could come and get me if the dog had her puppies.  By morning, it was all over.  Bagel crawled in my daughter’s sleeping bag, had half a dozen puppies and my daughter slept through the entire thing.

By the time Bagel’s puppies were weaned and adopted, she had woven herself into our family and our hearts.  Plus, she had bitten me over a disagreement over a piece of meat she pushed a chair to the counter to steal.  That made her unplaceable.  Extremely smart, but the Humane Society could not place a dog known to have bitten.  So, Bagel became ours.  Maybe she was even smarter than I gave her credit for.  She never bit me again or even tried to.

Bagel lived for nearly 20 years.  She outlived all of the dogs who joined the family after she did.  She was irascible and stubborn to a fault and chewed whatever she could get away with chewing – including a piece of needlework I was working on.  I told her she used one of her lives that day.

Bagel was my special friend who would honk the horn in the car if I went into the convenience store and was gone for more than 2 minutes.  She would go on vacation with us and would “point” to other creatures in need.  Solely because of Bagel, we rescued orphan baby birds, a seagull and yes, a skunk.

For a long time, she was terrified of men and of rough dirt roads, telling me she had probably been an ill-used and abused hunting dog.

If you were “hers,” she would defend you to the death. She did not want unknown men to approach me or my daughter, ever.  And she “explained” that to two different men with bad judgment.

Bagel survived cancer, twice.  Bagel comforted me upon the loss of my father, husband and sister.  She was my constant companion.

She was a master of stealing the hamburger patty out of the hamburger without touching the bun at all – especially in a moving car.  I can’t tell you how many meatless sandwiches I ate.  Bagel claimed she had NO idea what happened to that hamburger.

Bagel camped and hiked with us and loved to go to the ice cream store.  One time she managed to shut herself in the pantry for the day and ate bites of almost everything – and all of some things.  We found her in a food coma when we got home that day – and she still didn’t want to come out of the pantry.  She hid under the shelf.  She spent the rest of her life trying to get shut in the pantry again.

Most of all, she loved to go to see my mother on the farm.  The farm has SO MANY good smells and nasty rotten smelly things to roll in.

After my former husband’s stroke, he was in a rehab facility for about 6 months.  With proper permissions and vet paperwork, dogs were allowed to visit family members.  Bagel went along most everyday and she went room to room, visiting every person in his wing of the building.  She was the hit of the day and everyone looked forward to her daily rounds.  One day, she disappeared from my husband’s room, and she was taking herself on her rounds.  When someone was dismissed, she would sit in their room and cry.  If someone was having a bad day, she would crawl up with them to comfort them.  One time I found her in bed with a patient.

Bagel slept with me every night for 20 years, sometimes after a bath, if we had been visiting the farm, which is more than I can say for any human, at least so far.

Bagel lived to be old, quite old, more than 20, but still left us all too soon.

Bagel

But you know, I think Bagel has a hand in this Ellie thing.  You see, Ellie reminds me a little of Bagel.  She came to us in a world of hurt, but is loving and irascible, chews everything, doesn’t listen worth a darn and makes a loving pain of herself.  Yep – I think Bagel’s pawprints are all over this.

You know, they may need us, but we need them too.  Our lives are so greatly enriched by our fur family.  The gaping holes in our heart when they leave us reflect the great depth of our love for them.

Yep, I can’t wait till Ellie gets here to visit today.  Merry Christmas!

Peopling of Europe 2014 – Identifying the Ghost Population

Beginning with the full sequencing of the Neanderthal genome, first published in May 2010 by the Max Planck Institute with Svante Paabo at the helm, and followed shortly thereafter with a Denisovan specimen, we began to unravel our ancient history.

The photo below shows a step in the process of extracting DNA from ancient bones at Max Planck.

Our Y and mitochondrial DNA haplogroups take us back thousands of years in time, but at some point, where and how people were settling and intermixing becomes fuzzy. Ancient DNA can put the people of that time and place in context.  We have discovered that current populations do not necessarily represent the ancient populations of a particular locale.

Recent information discovered from ancient burials tells us that the people of Europe descend from a 3 pronged model. Until recently, it was believed that Europeans descended from Paleolithic hunter-gatherers and Neolithic farmers, a two-pronged model.

Previously, it was believed that Europe was peopled by the ancient hunter-gatherers, the Paleolithic, who originally settled in Europe beginning about 45,000 years ago. At this time, the Neanderthal were already settled in Europe but weren’t considered to be anatomically modern humans, and it was believed, incorrectly, that the two groups did not interbreed.  These hunter-gatherers were the people who settled in Europe before the last major ice age, the Younger Dryas, taking refuge in the southern portions of Europe and Eurasia, and repeopling the continent after the ice receded, about 12,000 years ago.  By that time, the Neanderthals were gone, or as we now know, at least partially assimilated.

This graphic shows Europe during the last ice age.

The second settlement wave, the agriculturalist farmers from the Near East either overran or integrated with the hunter-gatherers in the Neolithic period, depending on which theory you subscribe to, about 8000-10,000 years ago.

2012 – Ancient Northern European (ANE) Hints

Beginning in 2012, we began to see hints of a third lineage that contributed to the peopling of Europe as well, from the north. Buried in the 2012 paper, Estimating admixture proportions and dates with ADMIXTOOLS by Patterson et al, was a very interesting tidbit.  This new technique showed a third population, referred to by many as a “ghost population”, because no one knew who they were, that contributed to the European population.

patterson ane

The new population was termed Ancient North Eurasian, or ANE.

Dienekes covered this paper in his blog, but without additional information, in the community in general, there wasn’t much more than a yawn.

2013 – Mal’ta Child Stirs Excitement

The first real hint of meat on the bones of ANE came in the form of ancient DNA analysis of a 24,000 year old Siberian boy that has come to be named Mal’ta (Malta) Child. In the original paper, by Raghaven et al, Upper Palaeolithic Siberian genome reveals dual ancestry of Native Americans, he was referred to as MA-1.  I wrote about this in my article titled Native American Gene Flow – Europe?, Asia and the Americas.   Dienekes wrote about this paper as well.

This revelation caused quite a stir, because it was reported that the Ancestor of Native Americans in Asia was 30% Western Eurasian.  Unfortunately, in some cases, this was immediately interpreted to mean that Native Americans had come directly from Europe which is not what this paper said, nor inferred.  It was also inferred that the haplogroups of this child, R* (Y) and U (mtDNA) were Native American, which is also incorrect.  To date, there is no evidence for migration to the New World from Europe in ancient times, but that doesn’t mean we aren’t still looking for that evidence in early burials.

What this paper did show was that Europeans and Native Americans shared a common ancestor, and that the Siberian population had contributed to the European population as well as the Native American population.  In other words, descendants settled in both directions, east and west.

The most fascinating aspect of this paper was the match distribution map, below, showing which populations Malta child matched most closely.

As you can see, MA-1, Malta Child, matches the Native American population most closely, followed by the northern European and Greenland populations. The further south in Europe and Asia, the more distant the matches and the darker the blue.

2013 – Michael Hammer and Haplogroup R

Last fall at the Family Tree DNA conference, Dr. Michael Hammer, from the Hammer Lab at the University of Arizona discussed new findings relative to ancient burials, specifically in relation to haplogroup R, or more specifically, the absence of haplogroup R in those early burials.

hammer 2013-1

hammer 2013-2

hammer 2013-3

Based on the various theories and questions, ancient burials were enlightening.

hammer 2013-4

hammer 2013-5

In 2013, there were a total of 32 burials from the Neolithic period, after farmers arrived from the Near East, and haplogroup R did not appear. Instead, haplogroups G, I and E were found.

hammer 2013-7

What this tells us is that haplogroup R, as well as other haplogroup, weren’t present in Europe at this time. Having said this, these burials were in only 4 locations and, although unlikely, R could be found in other locations.

hammer 2013-11

Last year, Dr. Hammer concluded that haplogroup R was not found in the Paleolithic and likely arrived with the Neolithic farmers. That shook the community, as it had been widely believed that haplogroup R was one of the founding European haplogroups.

hammer 2013-12

While this provided tantalizing information, we still needed additional evidence. No paper has yet been published that addresses these findings.  The mass full sequencing of the Y chromosome over this past year with the introduction of the Big Y will provide extremely valuable information about the Y chromosome and eventually, the migration path into and across Europe.

2014 – Europe’s Three Ancient Tribes

In September 2014, another paper was published by Lazaridis et al that more fully defined this new ANE branch of the European human family tree.  An article in BBC News titled Europeans drawn from three ancient ‘tribes’ describes it well for the non-scientist.  Of particular interest in this article is the artistic rendering of the ancient individual, based on their genetic markers.  You’ll note that they had dark skin, dark hair and blue eyes, a rather unexpected finding.

In discussing the paper, David Reich from Harvard, one of the co-authors, said, “Prior to this paper, the models we had for European ancestry were two-way mixtures. We show that there are three groups. This also explains the recently discovered genetic connection between Europeans and Native Americans.  The same Ancient North Eurasian group contributed to both of them.”

The paper, Ancient human genomes suggest three ancestral populations for present-day Europeans, appeared as a letter in Nature and is behind a paywall, but the supplemental information is free.

The article summary states the following:

We sequenced the genomes of a ~7,000-year-old farmer from Germany and eight ~8,000-year-old hunter-gatherers from Luxembourg and Sweden. We analysed these and other ancient genomes1, 2, 3, 4 with 2,345 contemporary humans to show that most present-day Europeans derive from at least three highly differentiated populations: west European hunter-gatherers, who contributed ancestry to all Europeans but not to Near Easterners; ancient north Eurasians related to Upper Palaeolithic Siberians3, who contributed to both Europeans and Near Easterners; and early European farmers, who were mainly of Near Eastern origin but also harboured west European hunter-gatherer related ancestry. We model these populations’ deep relationships and show that early European farmers had ~44% ancestry from a ‘basal Eurasian’ population that split before the diversification of other non-African lineages.

This paper utilized ancient DNA from several sites and composed the following genetic contribution diagram that models the relationship of European to non-European populations.

2014 – Michael Hammer on Europe’s Ancestral Population

For anyone interested in ancient DNA, 2014 has been a banner years. At the Family Tree DNA conference in Houston, Texas, Dr. Michael Hammer brought the audience up to date on Europe’s ancestral population, including the newly sequenced ancient burials and the information they are providing.

hammer 2014

hammer 2014-1

Dr. Hammer said that ancient DNA is the key to understanding the historical processes that led up to the modern. He stressed that we need to be careful inferring that the current DNA pattern is reflective of the past because so many layers of culture have occurred between then and now.

hammer 2014-2

Until recently, it was assumed that the genes of the Neolithic farmers replaced those of the Paleolithic hunter-gatherers. Ancient DNA is suggesting that this is not true, at least not on a wholesale level.

hammer 2014-3

The theory, of course, is that we should be able to see them today if they still exist. The migration and settlement pattern in the slide below was from the theory set forth in the 1990s.

hammer 2014-4

In 2013, Dr. Hammer discussed the theory that haplogroup R1b spread into Europe with the farmers from the Near East in the Neolithic. This year, he expanded upon that topic that based on the new findings from ancient burials.

hammer 2014-5

Last year, Dr. Hammer discussed 32 burials from 4 sites. Today, we have information from 15 ancient DNA sites and many of those remains have been full genome sequenced.

hammer 2014-6

Information from papers and recent research suggests that Europeans also have genes from a third source lineage, nicknamed the “ghost population of North Eurasia.”

hammer 2014-7

Scientists are finding a signal of northeast Asian related admixture in northern Europeans, first suggested in 2012.  This was confirmed with the sequencing of Malta child and then in a second sequencing of Afontova Gora2 in south central Siberia.

hammer 2014-8

We have complete genomes from nine ancient Europeans – Mesolithic hunter gatherers and Neothilic farmers. Hammer refers to the Mesolithic here, which is a time period between the Paleolithic (hunter gatherers with stone tools) and the Neolithic (farmers).

hammer 2014-9

In the PCA charts, shown above, you can see that Europeans and people from the Near East cluster separately, except for a bridge formed by a few Mediterranean and Jewish populations. On the slide below, the hunter-gatherers (WHG) and early farmers (EEF) have been overlayed onto the contemporary populations along with the MA-1 (Malta Child) and AG2 (Afontova Gora2) representing the ANE.

hammer 2014-10

When sequenced, separate groups formed including western hunter gathers and early european farmers include Otzi, the iceman.  A third group is the north south clinal variation with ANE contributing to northern European ancestry.  The groups are represented by the circles, above.

hammer 2014-11

hammer 2014-12

Dr. Hammer said that the team who wrote the “Ancient Human Genomes” paper just recently published used an F3 test, results shown above, which shows whether populations are an admixture of a reference population based on their entire genome. He mentioned that this technique goes well beyond PCA.

hammer 2014-13

Mapped onto populations today, most European populations are a combination of the three early groups. However, the ANE is not found in the ancient Paleolithic or Neolithic burials.  It doesn’t arrive until later.

hammer 2014-14

This tells us that there was a migration event 45,000 years ago from the Levant, followed about 7000 years ago by farmers from the Near East, and that ANE entered the population some time after that. All Europeans today carry some amount of ANE, but ancient burials do not.

These burials also show that southern Europe has more Neolithic farmer genes and northern Europe has more Paleolithic/Mesolithic hunter-gatherer genes.

hammer 2014-15

Pigmentation for light skin came with farmers – blue eyes existed in hunter gatherers even though their skin was dark.

hammer 2014-16

Dr. Hammer created these pie charts of the Y and mitochondrial haplogroups found in the ancient burials as compared to contemporary European haplogroups.

hammer 2014-17

The pie chart on the left shows the haplogroups of the Mesolithic burials, all haplogroup I2 and subclades. Note that in the current German population today, no I2a1b and no I1 was found.  The chart on the right shows current Germans where haplogroup I is a minority.

hammer 2014-18

Therefore, we can conclude that haplogroup I is a good candidate to be identified as a Paleolithic/Mesolithic haplogroup.

This information shows that the past is very different from today.

hammer 2014-19

In 2014 we have many more burials that have been sequenced than last year, as shown on the map above.

Green represents Neolithic farmers, red are Mesolithic hunter-gatherers, brown at bottom right represents more recent samples from the Metallic age.

hammer 2014-20

There are a total of 48 Neolithic burials where haplogroup G dominates. In the Mesolithic, there are a total of six haplogroup I.

This suggests that haplogroup I is a good candidate to be the father of the Paleolithic/Mesolithic and haplogroup G, the founding father of the Neolithic.

In addition to haplogroup G in the Neolithic, one sample of both E1b1b1 (M35) and C were also found in Spain.  E1b1b1 isn’t surprising given it’s north African genesis, but C was quite interesting.

The Metal ages, which according to wiki begin about 3300BC in Europe, is where haplogroup R, along with I1, first appear.

diffusion of metallurgy

Please note that the diffusion of melallurgy map above is not part of Dr. Hammer’s presentation. I have added it for clarification.

hammer 2014-21

Nothing is constant in Europe. The Y DNA was very upheaved, as indicated on the graphic above.  Mitochondrial DNA shifted from pre-Neolithic to Neolithic which isn’t terribly different from the present day.

Dr. Hammer did not say this, but looking at the Y versus the mtDNA haplogroups, I wonder if this suggests that indeed there was more of a replacement of the males in the population, but that the females were more widely assimilated. This would certainly make sense, especially if the invaders were warriors and didn’t have females with them.  They would have taken partners from the invaded population.

Haplogroup G represents the spread of farming into Europe.

hammer 2014-22

The most surprising revelation is that haplogroup R1b appears to have emerged after the Neolithic agriculture transition. Given that just three years ago we thought that haplogroup R1b was one of the original European settlers thousands of years ago, based on the prevalence of haplogroup R in Europe today, at about 50%, this is a surprising turn of events.  Last year’s revelation that R was maybe only 7000-8000 years old in Europe was a bit of a whammy, but the age of R in Europe in essence just got halved again and the source of R1b changed from the Near East to the Asian steppes.

Obviously, something conferred an advantage to these R1b men. Given that they arrived in the early Metalic age, was it weapons and chariots that enabled the R1b men who arrived to quickly become more than half of the population?

hammer 2014-23

The Bronze Age saw the first use of metal to create weapons. Warrior identity became a standard part of daily life.  Celts ranged over Europe and were the most dominant iron age warriors.  Indo-European languages and chariots arrived from Asia about this time.

The map above shows the Hallstadt and LaTene Celtic cultures in Europe, about 600BC. This was not a slide presented by Dr. Hammer.

hammer 2014-27

Haplogroup R1b was not found in an ancient European context prior to a Bell Beaker period burial in Germany 4.8-4.0 kya (thousand years ago, i.e. 4,800-4,000 years ago).  R1b arrives about 4.6 kya and is also found in a Corded Ware culture burial in Germany.  A late introduction of these lineages which now predominate in Europe corresponds to the autosomal signal of the entry of Asian and Eastern European steppe invaders into western Europe.

hammer 2014-28

Local expansion occurred in Europe of R1b subgroups U106, L21 and U152.

hammer 2014-29

hammer 2014-30

A current haplogroup R distribution map that reflects the findings of this past year is shown above.

Haplogroup I is interesting for another reason. It looks like haplogroup I2a1b (M423) may have been replaced by I1 which expanded after the Mesolithic.

hammer 2014-31

On the slide above, the Loschbour sample from Luxembourg was mapped onto a current haplogroup I SNP map where his closest match is a current day Russian.

One of the benefits of ancient DNA genome processing is that we will be able to map current trees into maps of old SNPs and be able to tell who we match most closely.

Autosomal DNA can also be mapped to see how much of our DNA is from which ancient population.

hammer 2014-32

Dr. Hammer mapped the percentages of European Mesolithic/Paleolithic hunter-gatherers in blue, Neolithic Farmers from the Near East in magenta and Asian Steppe Invaders representing ANE in yellow, over current populations. Note the ancient DNA samples at the top of the list.  None of the burials except for Malta Child carry any yellow, indicating that the ANE entered the European population with the steppe invaders; the same group that brought us haplogroup R and possibly I1.

Dr. Hammer says that ANE was introduced to and assimilated into the European population by one or more incursions. We don’t know today if ANE in Europeans is a result of a single blast event or multiple events.  He would like to do some model simulations and see if it is related to timing and arrival of swords and chariots.

We know too that there are more recent incursions, because we’re still missing major haplogroups like J.

The further east you go, meaning the closer to the steppes and Volga region, the less well this fits the known models. In other words, we still don’t have the whole story.

At the end of the presentation, Michael was asked if the whole genomes sequenced are also obtaining Y STR data, which would allow us to compare our results on an individual versus a haplogroup level. He said he didn’t know, but he would check.

Family Tree DNA was asked if they could show a personal ancient DNA map in myOrigins, perhaps as an alternate view. Bennett took a vote and that seemed pretty popular, which he interpreted as a yes, we’d like to see that.

In Summary

The advent of and subsequent drop in the price of whole genome sequencing combined with the ability to extract ancient DNA and piece it back together have provided us with wonderful opportunities.  I think this is jut the proverbial tip of the iceberg, and I can’t wait to learn more.
