Native American Gene Flow – Europe?, Asia and the Americas

Posted on November 22, 2013 by Roberta Estes

Pre-release information from the paper, “Upper Palaeolithic Siberian genome reveals dual ancestry of Native Americans” which included results and analysis of DNA sequencing of 24,000 year old skeletal remains of a 4 year old Siberian boy caused quite a stir. Unfortunately, it was also misconstrued and incorrectly extrapolated in some articles. Some people misunderstood, either unintentionally or intentionally, and suggested that people with haplogroups U and R are Native American. That is not what either the prerelease or the paper itself says. Not only is that information and interpretation incorrect, the paper itself with the detailed information wasn’t published until November 20^th, in Nature.

The paper is currently behind a paywall, so I’m going to discuss parts of it here, along with some additional information from other sources. To help with geography, the following google map shows the following locations: A=the Altai Republic, in Russia, B=Mal’ta, the location of the 24,000 year old skeletal remains and C=Lake Baikal, the region from where the Native American population originated in Asia.

Nature did publish an article preview. That information is in bold, italics and I will be commenting in nonbold, nonitalics.

The origins of the First Americans remain contentious. Although Native Americans seem to be genetically most closely related to east Asians^{1, 2, 3}, there is no consensus with regard to which specific Old World populations they are closest to^{4, 5, 6, 7, 8}. Here we sequence the draft genome of an approximately 24,000-year-old individual (MA-1), from Mal’ta in south-central Siberia⁹, to an average depth of 1×. To our knowledge this is the oldest anatomically modern human genome reported to date.

Within the paper, the authors also compare the MA-1 sequence to that of another 40,000 year old individual from Tianyuan Cave, China whose genome has been partially sequenced. This Chinese individual has been shown to be ancestral to both modern-day Asians and Native Americans. This comparison was particularly useful, because it showed that MA-1 is not closely related to the Tianyuan Cave individual, and is more closely related to Native Americans. This means that MA-1’s line and Tianyuan Cave’s line had not yet met and admixed into the population that would become the Native Americans. That occurred sometime later than 24,000 years ago and probably before crossing Beringia into North America sometime between about 18,000 and 20,000 years ago.

The MA-1 mitochondrial genome belongs to haplogroup U, which has also been found at high frequency among Upper Palaeolithic and Mesolithic European hunter-gatherers^{10, 11, 12}, and the Y chromosome of MA-1 is basal to modern-day western Eurasians and near the root of most Native American lineages⁵.

The paper goes on to say that MA-1 is a member of mitochondrial (maternal) haplogroup U, very near the base of that haplogroup, but without affiliation to any known subclade, implying either that the subclade is rare or extinct in modern populations. In other words, this particular line of haplogroup U has NOT been found in any population, anyplace. According to the landmark paper, “A ‘‘Copernican’’ Reassessment of the Human Mitochondrial DNA Tree from its Root,” by Behar et al, 2012, haplogroup U itself was born about 46,500 years ago (plus or minus 3.200 years) and today has 9 major subclades (plus haplogroup K) and about 300 branching clades from those 9 subclades, excluding haplogroup K.

The map below, from the supplemental material included with the paper shows the distribution of haplogroup U, the black dots showing locations of haplogroup U comparison DNA.

In a recent paper, “Ancient DNA Reveals Key Stages in the Formation of Central European Mitochondrial Genetic Diversity” by Brandt et al (including the National Geographic Consortium) released in October 2013, the authors report that in the 198 ancient DNA samples collected from 25 German sites and compared to almost 68,000 current results, all of the ancient Hunter-Gatherer cultural results were haplogroup U, U4, U5 and U8. No other haplogroups were represented. In addition, those haplogroups disappeared from the region entirely with the advent of farming, shown on the chart below.

So, if someone who carries haplogroup U wants to say that they are distantly related to MA-1 who lived 24,000 years ago who was also related to their common ancestor who lived sometime prior to that, between 24,000 and 50,000 years ago, probably someplace between the Middle East where U was born, Mal’ta, Siberia and Western Europe, they would be correct. They are also distantly related to every other person in the world who carries haplogroup U, and many much more closely that MA-1 whose mitochondrial DNA line is either rare as chicken’s teeth (i.e. never found) or has gone extinct.

Let me be very clear about this, there is no evidence, none, that mitochondrial haplogroup U is found in the Native American population today that is NOT a result of post-contact admixture. In other words, in the burials that have been DNA tested, there is not one example in either North or South America of a burial carrying mitochondrial haplogroup U, or for that matter, male Y haplogroup R. Native American haplogroups found in the Americas remain subsets of mitochondrial haplogroups A, B, C, D and X and Y DNA haplogroups C and Q. Mitochondrial haplogroup M has potentially been found in one Canadian burial. No other haplogroups have been found. Until pre-contact remains are found with base haplogroups other than the ones listed above, no one can ethically claim that other haplogroups are of Native American origin. Finding any haplogroup in a contemporary Native population does not mean that it was originally Native, or that it should be counted as such. Admixture and adoption have been commonplace since Europeans first set foot on the soil of the Americas.

Now let’s talk about the Y DNA of MA-1.

The authors state that MA-1’s results are found very near the base of haplogroup R. They note that the sister lineage of haplogroup R, haplogroup Q, is the most common haplogroup in Native Americans and that the closest Eurasian Q results to Native Americans come from the Altai region.

The testing of the MA-1 Y chromosome was much more extensive than the typical STR genealogy tests taken by consumers today. MA-1’s Y chromosome was sequenced at 5.8 million base pairs at a coverage of 1.5X.

The resulting haplotree is shown below, again from the supplementary material.

The current haplogroup distribution range for haplogroup R is shown below, again with comparison points as black dots.

The current distribution range for Eurasian haplogroup Q is shown on the map below. Haplogroup Q is the most common haplogroup in Native Americans.

Similarly, we find autosomal evidence that MA-1 is basal to modern-day western Eurasians and genetically closely related to modern-day Native Americans, with no close affinity to east Asians. This suggests that populations related to contemporary western Eurasians had a more north-easterly distribution 24,000 years ago than commonly thought. Furthermore, we estimate that 14 to 38% of Native American ancestry may originate through gene flow from this ancient population. This is likely to have occurred after the divergence of Native American ancestors from east Asian ancestors, but before the diversification of Native American populations in the New World. Gene flow from the MA-1 lineage into Native American ancestors could explain why several crania from the First Americans have been reported as bearing morphological characteristics that do not resemble those of east Asians^{2, 13}.

Kennewick Man is probably the most famous of the skeletal remains that don’t neatly fit into their preconceived box. Kennewick man was discovered on the bank of the Columbia River in Kennewick, Washington in 1996 and is believed to be from 7300 to 7600 years old. His anatomical features were quite different from today’s Native Americans and his relationship to ancient people is unknown. An initial evaluation and a 2010 reevaluation of Kennewick Man let to the conclusion by Doug Owsley, a forensic anthropologist, that Kennewick Man most closely resembles the Ainu people of Japan who themselves are a bit of an enigma, appearing much more Caucasoid than Asian. Unfortunately, DNA sequencing of Kennewick Man originally was ussuccessful and now, due to ongoing legal issues, more technologically advanced DNA testing has not been allowed. Nova sponsored a facial reconstruction of Kennewick Man which you can see here.

Sequencing of another south-central Siberian, Afontova Gora-2 dating to approximately 17,000 years ago¹⁴, revealed similar autosomal genetic signatures as MA-1, suggesting that the region was continuously occupied by humans throughout the Last Glacial Maximum. Our findings reveal that western Eurasian genetic signatures in modern-day Native Americans derive not only from post-Columbian admixture, as commonly thought, but also from a mixed ancestry of the First Americans.

In addition to the sequencing they set forth above, the authors compared the phenotype information obtainable from MA-1 to the Tyrolean Iceman, typically called Otzi. You can see Otzi’s facial reconstruction along with more information here. This is particularly interesting in light of the pigmentation change from darker skin in Africa to lighter skin in Eurasia, and the question of when this appearance change occurred. MA-1 shows a genetic affinity with the contemporary people of northern Europe, the population today with the highest frequency of light pigmentation phenotypes. The authors compared the DNA of MA-1 with a set of 124 SNPs identified in 2001 by Cerquira as informative on skin, hair and eye pigmentation color, although they also caution that this method has limited prediction accuracy. Given that, they say that MA-1 had dark hair, skin and eyes, but they were not able to sequence the full set of SNPs. MA-1 also had the SNP value associated with a high risk of male pattern baldness, a trait seldom found in Native American people and was not lactose tolerant, a trait found in western Eurasians. MA-1 also does not carry the mutation associated with hair thickness and shovel shaped incisors in Asians.

The chart below from the supplemental material shows the comparison with MA-1 and the Tyrolean Iceman.

The Tarim Mummies, found in the Tarim Basin in present-day Xinjiang, China are another example of remains that seem out of place. The earliest Tarim mummies, found at Qäwrighul and dated to 1800 BCE, are of a Europoid physical type whose closest affiliation is to the Bronze Age populations of southern Siberia, Kazakhstan, Central Asia, and the Lower Volga.

The cemetery at Yanbulaq contained 29 mummies which date from 1100–500 BCE, 21 of which are Mongoloid—the earliest Mongoloid mummies found in the Tarim Basin—and eight of which are of the same Europoid physical type found at Qäwrighul.

Notable mummies are the tall, red-haired “Chärchän man” or the “Ur-David” (1000 BCE); his son (1000 BCE), a small 1-year-old baby with brown hair protruding from under a red and blue felt cap, with two stones positioned over its eyes; the “Hami Mummy” (c. 1400–800 BCE), a “red-headed beauty” found in Qizilchoqa; and the “Witches of Subeshi” (4th or 3rd century BCE), who wore 2-foot-long (0.61 m) black felt conical hats with a flat brim. Also found at Subeshi was a man with traces of a surgical operation on his neck; the incision is sewn up with sutures made of horsehair.

Their costumes, and especially textiles, may indicate a common origin with Indo-European neolithic clothing techniques or a common low-level textile technology. Chärchän man wore a red twill tunic and tartan leggings. Textile expert Elizabeth Wayland Barber, who examined the tartan-style cloth, discusses similarities between it and fragments recovered from salt mines associated with the Hallstatt culture.

DNA testing revealed that the maternal lineages were predominantly East Eurasian haplogroup C with smaller numbers of H and K, while the paternal lines were all R1a1a. The geographic location of where this admixing took place is unknown, although south Siberia is likely. You can view some photographs of the mummies here.

In closing, the authors of the MA-1 paper state that the study has four important implications.

First, we find evidence that contemporary Native Americans and western Eurasians shareancestry through gene flow from a Siberian Upper Palaeolithic population into First Americans.

Second, our findings may provide an explanation for the presence of mtDNA haplogroup X in Native Americans, which is related to western Eurasians but not found in east Asian populations.

Third, such an easterly presence in Asia of a population related to contemporary western Eurasians provides a possibility that non-east Asian cranial characteristics of the First Americans derived from the Old World via migration through Beringia, rather than by a trans-Atlantic voyage from Iberia as proposed by the Solutrean hypothesis.

Fourth, the presence of an ancient western Eurasian genomic signature in the Baikal area before and after the LGM suggests that parts of south-central Siberia were occupied by humans throughout the coldest stages of the last ice age.

The times, they are a changin’.

Dr. Michael Hammer’s presentation at the 9^th Annual International Conference on Genetic Genealogy may shed some light on all of this seeming confusing and somewhat conflicting information.

The graphic below shows the Y haplogroup base tree as documented by van Oven.

You can see, in the lower right corner, that Y haplogroup K (not to be confused with mtDNA haplogroup K discussed in conjunction with mtDNA haplogroup U) was the parent of haplogroup P which is the parent of both haplogroups Q and R.

It has always been believed that haplogroup R made its way into Europe before the arrival of Neolithic farmers about 10,000 years ago. However, that conclusion has been called into question, also by the use of Ancient DNA results. You can view additional information about Hammer’s presentation here, but in a nutshell, he said that there is no early evidence in burials, at all, for haplogroup R being in Europe at an early age. In about 40 burials from several location, haplogroup R has never been found. If it were present, especially in the numbers expected given that it represents more than half of the haplogroups of the men of Europe today, it should be represented in these burials, but it is not. Hammer concludes that evidence supports a recent spread of haplogroup R into Europe about 5000 years ago. Where was haplogroup R before spreading into Europe? In Asia.

It appears that haplogroup K diversified in Southeast Asian, giving birth to haplogroups P, Q and R. Dr. Hammer said that this new information, combined with new cluster information and newly discovered SNP information over the past two years requires that haplogroup K be significantly revised. Between the revision of haplogroup K, the parent of both haplogroup R, previously believed to be European, and haplogroup Q, known to be Asian, European and Native, we may be in for a paradigm shift in terms of what we know about ancient migrations and who is whom. This path for haplogroup R into Europe really shouldn’t be surprising. It’s the exact same distribution as haplogroup Q, except haplogroup Q is much less frequently found in Europe than haplogroup R.

What Can We Say About MA-1?

In essence, we can’t label MA-1 as paternally European because of Y haplogroup R which now looks to have had an Asian genesis and was not known to have been in Europe 24,000 years ago, only arriving about 5,000 years ago. We can’t label haplogroup R as Native American, because it has never been found in a pre-Columbian New World burial.

We can say that mitochondrial haplogroup U is found in Europe in Hunter-Gatherer groups six thousand years ago (R was not) but we really don’t know if haplogroup U was in Europe 24,000 years ago. We cannot label haplogroup U as Native because it has never been found in a pre-Columbian New World burial.

We can determine that MA-1 did have ancestors who eventually became European due to autosomal analysis, but we don’t know that those people lived in what is now Europe 24,000 years ago. So the migration might have been into Europe, not out of Europe. MA-1, his ancestors and descendants, may have lived in Asia and subsequently settled in Europe or lived someplace inbetween. We can determine that MA-1’s line of people eventually admixed with people from East Asia, probably in Siberia, and became today’s First People of North and South America.

We can say that MA-1 appears to have been about 30% what is today Western Eurasian and that he is closely related to modern day Native Americans, but not eastern Asians. The authors estimate that between 14% and 38% of Native American ancestry comes from MA-1’s ancient population.

Whoever thought we could learn so much from a 4 year old?

For anyone seriously interested in Native American population genetics, “Upper Palaeolithic Siberian genome reveals dual ancestry of Native Americans” is a must read.

2013 Family Tree DNA Conference Day 2

Posted on November 12, 2013 by Roberta Estes

ISOGG Meeting

The International Society of Genetic Genealogy always meets at 8 AM on Sunday morning. I personally think that 8AM meeting should be illegal, but then I generally work till 2 or 3 AM (it’s 1:51 AM now), so 8 is the middle of my night.

Katherine Borges, the Director speaks about current and future activities, and Alice Fairhurst spoke about the many updates to the Y tree that have happened and those coming as well. It has been a huge challenge to her group to keep things even remotely current and they deserve a huge round of virtual applause from all of us for the Y tree and their efforts.

Bennett opened the second day after the ISOGG meeting.

“The fact that you are here is a testament to citizen science” and that we are pushing or sometimes pulling academia along to where we are.

Bennett told the story of the beginning of Family Tree DNA. “Fourteen years ago when the hair that I have wasn’t grey,” he began, “I was unemployed and tried to reorganize my wife’s kitchen and she sent me away to do genealogy.” Smart woman, and thankfully for us, he went. But he had a roadblock. He felt there was a possibility that he could use the Y chromosome to solve the roadblock. Bennett called the author of one of the two papers published at that time, Michael Hammer. He called Michael Hammer on Sunday morning at his home, but Michael was running out the door to the airport. He declined Bennett’s request, told him that’s not what universities do, and that he didn’t know of anyplace a Y test could be commercially be done. Bennett, having run out of persuasive arguments, started mumbling about “us little people providing money for universities.” Michael said to him, “Someone should start a company to do that because I get phone calls from crazy genealogists like you all the time.” Let’s just say Bennett was no longer unemployed and the rest, as they say, is history. With that, Bennett introduced one of our favorite speakers, Dr. Michael Hammer from the Hammer Lab at the University of Arizona.

Session 1 – Michael Hammer – Origins of R-M269 Diversity in Europe

Michael has been at all of the conferences. He says he doesn’t think we’re crazy. I personally think we’ve confirmed it for him, several times over, so he KNOWS we’re crazy. But it obviously has rubbed off on him, because today, he had a real shocker for us.

I want to preface this by saying that I was frantically taking notes and photos, and I may have missed something. He will have his slides posted and they will be available through a link on the GAP page at FTDNA by the end of the week, according to Elliott.

Michael started by saying that he is really exciting opportunity to begin breaking family groups up with SNPs which are coming faster than we can type them.

Michael rolled out the Y tree for R and the new tree looks like a vellum scroll.

Today, he is going to focus on the basic branches of the Y tree because the history of R is held there.

The first anatomically modern humans migrated from Africa about 45,000 years ago.

After last glacial maximum 17,000 years ago, there was a significant expansion into Europe.

Neolithic farmers arrived from the near east beginning 10,000 years ago.

Farmers had an advantage over hunter gatherers in terms of population density. People moved into Northwestern Europe about 5,000 years ago.

What did the various expansions contribute to the population today?

Previous studies indicate that haplogroup R has a Paleolithic origin, but 2 recent studies agree that this haplogroup has a more recent origin in Europe – the Neolithic but disagree about the timing of the expansion.

The first study, Joblin’s study in 2010, argued that geographic diversity is explained by single Near East source via Anaotolia.

It conclude that the Y of Mesololithic hunger-gatherers were nearly replaced by those of incoming farmers.

In the most recent study by Busby in 2012 is the largest study and concludes that there is no diversity in the mapping of R SNP markers so they could not date lineage and expansion. They did find that most basic structure of R tree did come from the near east. They looked at P311 as marker for expansion into Europe, wherever it was. Here is a summary page of Neolithic Europe that includes these studies.

Hammer says that in his opinion, he thought that if P311 is so frequent and widespread in Europe it must have been there a long time. However, it appears that he and most everyone else, was wrong.

The hypothesis to be tested is if P311 originated prior to the Neolithic wave, it would predict higher diversity it the near east, closer to the origins of agriculture. If P311 originated after the expansion, would be able to see it migrate across Europe and it would have had to replace an existing population.

Because we now have sequences the DNA of about 40 ancient DNA specimens, Michael turned to the ancient DNA literature. There were 4 primary locations with skeletal remains. There were caves in France, Spain, Germany and then there’s Otzi, found in the Alps.

All of these remains are between 6000-7000 years old, so prior to the agricultural expansion into Europe.

In France, the study of 22 remains produced, 20 that were G2a and 2 that were I2a.

In Spain, 5 G2a and 1 E1b.

In Germany, 1I G2a and 2 F*.

Otzi is haplogroup G2a2b.

There was absolutely 0, no, haplogroup R of any flavor.

In modern samples, of 172 samples, 94 are R1b.

To evaluate this, he is dropping back to the backbone of haplogroup R.

This evidence supports a recent spread of haplogroup R lineages in western Europe about 5K years ago. This also supports evidence that P311 moved into Europe after the Neolithic agricultural transition and nearly displaced the previously existing western European Neolithic Y, which appears to be G2a.

This same pattern does not extrapolate to mitochondrial DNA where there is continuity.

What conferred advantage to these post Neolithic men? What was that advantage?

Dr. Hammer then grouped the major subgroups of haplogroup R-P3111 and found the following clusters.

U106 is clustered in Germany
L21 clustered in the British Isles
U152 has an Alps epicenter

This suggests multiple centers of re-expansion for subgroups of haplogroup R, a stepwise process leading to different pockets of subhaplogroup density.

Archaeological studies produce patterns similar to the hap epicenters.

What kind of model is going on for this expansion?

Ancestral origin of haplogroup R is in the near east, with U106, P312 and L21 which are then found in 3 European locations.

This research also suggests thatG2a is the Neolithic version of R1b – it was the most commonly found haplogroup before the R invasion.

To make things even more interesting, the base tree that includes R has also been shifted, dramatically.

Haplogroup K has been significantly revised and is the parent of haplogroups P, R and Q.

It has been broken into 4 major branches from several individual lineages – widely shifted clades.

Haps R and Q are the only groups that are not restricted to Oceana and Southeast Asia.

Rapid splitting of lineages in Southeast Asia to P, R and Q, the last two of which then appear in western Europe.

R then, populated Europe in the last 4000 years.

How did these Asians get to Europe and why?

Asian R1b overtook Neolithic G2a about 4000 years ago in Europe which means that R1b, after migrating from Africa, went to Asia as haplogroup K and then divided into P, Q and R before R and Q returned westward and entered Europe. If you are shaking your head right about now and saying “huh?”…so were we.

Here is Dr. Hammer’s revised map of haplogroup dispersion.

Moving away from the base tree and looking at more recent SNPs, Dr. Hammer started talking about some of the findings from the advanced SNP testing done through the Nat Geo project and some of what it looks like and what it is telling us.

For example, the R1bs of the British Isles.

There are many clades under L 21. For example, there is something going on in Scotland with one particular SNP (CTS11722?) as it comprises one third of the population in Scotland, but very rare in Ireland, England and Wales.

New Geno 2.0 SNP data is being utilized to learn more about these downstream SNPs and what they had to say about the populations in certain geographies.

For example, there are 32 new SNPs under M222 which will help at a genealogical level.

These SNPs must have arisen in the past couple thousand years.

Michael wants to work with people who have significant numbers of individuals who can’t be broken out with STRs any further and would like to test the group to break down further with SNPs. The Big Y is one option but so is Nat Geo and traditional SNP testing, depending on the circumstance.

G2a is currently 4-5% of the population in Europe today and R is more than 40%.

Therefore, P312 split in western Eurasia and very rapidly came to dominate Europe

Session 2 – Dr. Marja Pirttivaara – Bridging Social Media and DNA

Dr. Pirttivaara has her PhD in Physics and is passionate about genetic genealogy, history and maps. She is an administrator for DNA projects related to Finland and haplogroup N1c1, found in Finland, of course.

Finland has the population of Minnesota and is the size of New Mexico.

There are 3750 Finland project members and of them 614 are haplogroup N1c1.

Combining the N1c1 and the Uralic map, we find a correlation between the distribution of the two.

Turku, the old capital, was full or foreigners, in Medieval times which is today reflected in the far reaching DNA matches to Finnish people.

Some of the interest in Finland’s DNA comes from migration which occurred to the United States.

Facebook and other social media has changed the rules of communication and allows the people from wide geographies to collaborate. The administrator’s role has also changed on social media as opposed to just a FTDNA project admin. Now, the administrator becomes a negotiator and a moderator as well as the DNA “expert.”

Marja has done an excellent job of motivating her project members. They are very active within the project but also on Facebook, comparing notes, posting historical information and more.

Session 3 – Jason Wang – Engineering Roadmap and IT Update

Jason is the Chief Technology Officer at Family Tree DNA and recently joined with the Arpeggi merger and has a MS in Computer Engineering.

Regarding the Gene by Gene/FTDNA partnership, “The sum of the parts is greater than the whole.” He notes that they have added people since last year in addition to the Arpeggi acquisition.

Jason introduced Elliott Greenspan, who, to most of us, needed no introduction at all.

Elliott began manually scoring mitochondrial DNA tests at age 15. He joined FTDNA in 2006 officially.

Year in review and What’s Coming

4 times the data processed in the past year.

Uploads run 10 times faster. With 23andMe and Ancestry autosomal uploads, processing will start in about 5 minutes, and matches will start then.

FTDNA reinvented Family Finder with the goal of making the user experience easier and more modern. They added photos, profiles and the new comparison bars along with an advanced section and added push to chromosome browser.

Focus on users uploading the family tree. Tools don’t matter if the data isn’t there. In order to utilize the genealogy aspect, the genealogy info needs to be there. Will be enhancing the GEDCOM viewer. New GEDCOMs replace old GEDCOMs so as you update yours, upload it again.

They are now adding a SNP request form so that you can request a SNP not currently available. This is not to be confused with ordering an existing SNP.

They currently utilize build 14 for mitochondrial DNA. They are skipping build 15 entirely and moving forward with 16.

They added steps to the full sequence matches so that you can see your step-wise mutations and decide whether and if you are related in a genealogical timeframe.

New Y tree will be released shortly as a result of the Geno 2.0 testing. Some of the SNPs have mutated as much as 7 times, and what does that mean in terms of the tree and in terms of genealogical usefulness. This tree has taken much longer to produce than they expected due to these types of issues which had to be revised individually.

New 2014 tree has 6200 SNPS and 1000 branches.

Commitment to take genetic genealogy to the next level
Y draft tree
Constant updates to official tree
Commitment to accurate science

If a single sample comes back as positive for a SNP, they will put it on the tree and will constantly update this.

If 3 or 4 people have the same SNP that are not related it will go directly to the tree. This is the reason for the new SNP request form.

Part of the reason that the tree has taken so long is that not every SNP is public and it has been a huge problem.

When they find a new SNP, where does it go on the tree? When one SNP is found or a SNP fails, they have run over 6000 individual SNPs on Nat Geo samples to vet to verify the accuracy of the placement. For example, if a new SNP is found in a particular location, or one is found not to be equivalent that was believe to be so previously, they will then test other samples to see where the SNP actually belongs.

X Matching

Matching differential is huge in early testing. One child may inherit as little as 20% of the X and another 90%. Some first cousins carry none.

X matching will be an advanced feature and will have their own chromosome browser.

End of the year – January 1. Happy New Year!!!

Population Finder

It’s definitely in need of an upgrade and have assigned one person full time to this product.

There are a few contention points that can be explained through standard history.

It’s going to get a new look as well and will be easily upgradeable in the future.

They cannot utilize the National Geographic data because it’s private to Nat Geo.

Bennett – “Committed to an engineering team of any size it takes to get it done. New things will be rolling out in first and second quarter of next year.” Then Bennett kind of sighed and said “I can’t believe I just said that.”

Session 4 – Dr. Connie Bormans – Laboratory Update

The Gene by Gene lab, which of course processes all of the FTDNA samples is now a regulated lab which allows them to offer certain regulated medical tests.

CLIA
CAP
AABB
NYSDOH

Between these various accreditations, they are inspected and accredited once yearly.

Working to decrease turn-around time.

SNP request pipeline is an online form and is in place to request a new SNP be added to their testing menu.

Raised the bar for all of their tests even though genetic genealogy isn’t medical testing because it’s good for customers and increases quality and throughput.

New customer support software and new procedures to triage customer requests.

Implement new scoring software that can score twice as many tests in half the time. This decreases turn-around time to the customer as well.

New projects include improved method of mtDNA analysis, new lab techniques and equipment and there are also new products in development.

Ancient DNA (meaning DNA from deceased people) is being considered as an offering if there is enough demand.

Session 5 – Maurice Gleeson – Back to Our Past, Ireland

Maurice Gleeson coordinated a world class genealogy event in Dublin, Ireland Oct. 18-20, 2013. Family Tree DNA and ISOGG volunteers attended to educate attendees about genetic genealogy and DNA. It was a great success and the DNA kits from the conference were checked in last week and are in process now. Hopefully this will help people with Irish ancestry.

12% of the Americans have Irish ancestry, but a show of hands here was nearly 100% – so maybe Irish descendants carry the crazy genealogist gene!

They developed a website titled Genetic Genealogy Ireland 2013. Their target audience was twofold, genetic genealogy in general and also the Irish people. They posted things periodically to keep people interested. They also created a Facebook page. They announced free (sponsored) DNA tests and the traffic increased a great deal. Today ISOGG has a free DNA wiki page too. They also had a prize draw sponsored by the Ireland DNA and mtdna projects. Maurice said that the sessions and the booth proximity were quite symbiotic because when y ou came out of the DNA session, the booth was right there.

2000-5000 people passed by the booth

500 people in the booth

Sold 99 kits – 119 tests

45 took Y 37 marker tests

56 FF, 20 male, 36 female

18 mito tests

They passed out a lot of educational material the first two days. It appeared that the attendees were thinking about things and they came back the last day which is when half of the kits were sold, literally up until they threatened to turn the lights out on them.

They have uploaded all of the lectures to a YouTube channel and they have had over 2000 views. Of all of the presentation, which looked to be a list of maybe 10-15, the autosomal DNA lecture has received 25% of the total hits for all of the videos.

This is a wonderful resource, so be sure to watch these videos and publicize them in your projects.

Session 6 – Brad Larkin – Introducing Surname DNA Journal

Brad Larkin is the FTDNA video link to the “how to appropriately” scrape for a DNA test. That’s his minute or two of fame! I knew he looked familiar.

Brad began a peer reviewed genetic genealogy journal in order to help people get their project stories published. It’s free, open access, web based and the author retains the copyright.. www.surnamedna.com

Conceived in 2012, the first article was published in January 2013. Three papers published to date.

Encourage administrators to write and publish their research. This helps the publication withstand the test of time.

Most other journals are not free, except for JOGG which is now inactive. Author fees typically are $1320 (PLOS) to $5000 (Nature) and some also have subscription or reader fees.

Peer review is important. It is a critical review, a keen eye and an encouraging tone. This insures that the information is evidence based, correct and replicable.

Session 7 – mtdna Roundtable – Roberta Estes and Marie Rundquist

This roundtable was a much smaller group than yesterday’s Y DNA and SNP session, but much more productive for the attendees since we could give individual attention to each person. We discussed how to effectively use mtdna results and what they really mean. And you just never know what you’re going to discover. Marie was using one of her ancestors whose mtDNA was not the haplogroup expected and when she mentioned the name, I realized that Marie and I share yet another ancestral line. WooHoo!!

Q&A

FTDNA kits can now be tested for the Nat Geo test without having to submit a new sample.

After the new Y tree is defined, FTDNA will offer another version of the Deep Clade test.

Illumina chip, most of the time, does not cover STRs because it measures DNA in very small fragments. As they work with the Big Y chip, if the STRs are there, then they will be reported.

80% of FTDNA orders are from the US.

Microalleles from the Houston lab are being added to results as produced, but they do not have the data from the older tests at the University of Arizona.

Holiday sale starts now, runs through December 31 and includes a restaurant.com $100 gift card for anyone who purchases any test or combination of tests that includes Family Finder.

That’s it folks. We took a few more photos with our friends and left looking forward to next year’s conference. Below, left to right in rear, Marja Pirttivaara, Marie Rundquist and David Pike. Front row, left to right, me and Bennett Greenspan.

See y’all next year!!!

2013 Family Tree DNA Conference Day 1

Posted on November 11, 2013 by Roberta Estes

This article is probably less polished than my normal articles. I’d like to get this information out and to you sooner rather than later, and I’m still on the road the rest of this week with little time to write. So you’re getting a spruced up version of my notes. There are some articles here I’d like to write about more indepth later, after I’m back at home and have recovered a bit.

Max Blankfield and Bennett Greenspan, founders, opened the conference on the first day as they always do. Max began with a bit of a story.

13 years ago Bennett started on a quest….

Indeed he did, and later, Bennett will be relating his own story of that journey.

Someone mentioned to Max that this must be a tough time in this industry. Max thought about this and said, really, not. Competition validates what you are doing.

For competition it’s just a business opportunity – it was not and is not approached with the passion and commitment that Family Tree DNA has and has always had.

He said this has been their best year ever and great things in the pipeline.

One of the big moves is that Arpeggi merged into Family Tree DNA.

10^th Anniversary Pioneer Awards

Quite unexpectedly, Max noted and thanked the early adopters and pioneers, some of which who are gone now but remain with us in spirit.

Max and Bennett recognized the administrators who have been with Family Tree DNA for more than 10 years. The list included about 20 or so early adopters. They provided plaques for us and many of us took a photo with Max as the plaques were handed out.

I am always impressed by the personal humility and gratitude of Max and Bennett, both, to their administrators. A good part of their success is attributed, I’m sure, to their personal commitment not only to this industry, but to the individual people involved. When Max noted the admins who were leaders and are no longer with us, he could barely speak. There were a lot of teary eyes in the room, because they were friends to all of us and we all have good memories.

Thank you, Max and Bennett.

The second day, we took a group photo of all of the recipients along with Max and Bennett.

With that, it was Bennett’s turn for a few remarks.

Bennett says that having their own lab provides a wonderful environment and allows them to benchmark and respond to an ever changing business environment.

Today, they are a College of American Pathologists certified lab and tomorrow, we will find out more about what is coming. Tomorrow, David Mittleman will speak about next generation sequencing.

The handout booklet includes the information that Family Tree DNA now includes over 656,898 records in more than 8,700 group projects. These projects are all managed by volunteer administrators, which in and of itself, is a rather daunting number and amount of volunteer crowd-sourcing.

Session 1 – Amy McGuire, PhD, JD – Am I My Brother’s Keeper?

Dr. McGuire went to college for a very long time. Her list of degrees would take a page or so. She is the Director of the Center for Medical Ethics and Health Policy at Baylor College of Medicine.

Thirteen years ago, Amy’s husband was sitting next to Bennett’s wife on an airplane and she gave him a business card. Then two months ago, Amy wound up sitting next to Max on another airplane. It’s a very small world.

I will tell you that Amy said that her job is asking the difficult questions, not providing the answers. You’ll see from what follows that she is quite good at that.

How is genetic genealogy different from clinical genetics in terms of ethics and privacy? How responsible are we to other family members who share our DNA?

What obligations do we have to relatives in all areas of genetics – both clinical, direct to consumer that related to medical information and then for genetic genealogy.

She referenced the article below, which I blogged about here. There was unfortunately, a lot of fallout in the media.

Identifying Personal Genomes by Surname Inference – Science magazine in January 2013. I blogged about this at the time.

She spoke a bit about the history of this issue.

In 2004, a paper was published that stated that it took only 30 to 80 specifically selected SNPS to identify a person.

2008 – Can you identify an individual from pooled or aggregated or DNA? This is relevant to situations like 911 where the DNA of multiple individuals has been mixed together. Can you identify individuals from that brew?

2005 – 15 year old boy identifies his biological father who was a sperm donor. Is this a good thing or a bad thing? Some feel that it’s unethical and an invasion of the privacy of the father. But others feel that if the donor is concerned about that, they shouldn’t be selling their sperm.

Today, for children conceived from sperm donors, there are now websites available to identify half-siblings.

The movement today is towards making sure that people are informed that their anonymity may not be able to be preserved. DNA is the ultimate identifier.

Genetic Privacy – individual perspectives vary widely. Some individuals are quite concerned and some are not the least bit concerned.

Some of the concern is based in the eugenics movement stemming from the forced sterilization (against their will) of more than 60,000 Americans beginning in 1907. These people were considered to be of no value or injurious to the general population – meaning those institutionalized for mental illness or in prison.

1927 – Buck vs Bell – The Supreme court upheld forced sterilization of a woman who was the third generation institutionalized female for retardation. “Three generations of imbeciles is enough.” I must say, the question this leaves me with is how institutionalized retarded women got pregnant in what was supposed to be a “protected” environment.

Hitler, of course, followed and we all know about the Holocaust.

I will also note here that in my experience, concern is not rooted in Eugenics, but she deals more with medical testing and I deal with genetic genealogy.

The issues of privacy and informed consent have become more important because the technology has improved dramatically and the prices have fallen exponentially.

In 2012, the Nonopore OSB Sequencer was introduced that can sequence an entire genome for about $1000.

Originally, DNA data was provided in open access data bases and was anonymized by removing names. The data base from which the 2013 individuals were identified removed names, but included other identifying information including ages and where the individuals lived. Therefore, using Y-STRs, you could identify these families just like an adoptee utilizes data bases like Y-Search to find their biological father.

Today, research data bases have moved to controlled access, meaning other researchers must apply to have access so that their motivations and purposes can be evaluated.

In a recent medical study, a group of people in a research study were informed and educated about the utility of public data bases and why they are needed versus the tradeoffs, and then they were given a release form providing various options. 53% wanted their info in public domain, 33 in restricted access data bases and 13% wanted no data release. She notes that these were highly motivated people enrolled in a clinical study. Other groups such as Native Americans are much more skeptical.

People who did not release their data were concerned with uncertainly of what might occur in the future.

People want to be respected as a research participant. Most people said they would participate if they were simply asked. So often it’s less about the data and more about how they are treated.

I would concur with Dr. McGuire on this. I know several people who refused to participate in a research study because their results would not be returned to them personally. All they wanted was information and to be treated respectfully.

What the new genetic privacy issues are really all about is whether or not you are releasing data not just about yourself, but about your family as well. What rights or issues do the other family members have relative to your DNA?

Jim Watson, one of the discoverers of DNA, wanted to release his data publicly…except for his inherited Alzheimer’s status. It was redacted, but, you can infer the “answer” from surrounding (flanking regions) DNA. He has two children. How does this affect his children? Should his children sign a consent and release before their father’s genome is published, since part of it is their sequence as well? The academic community was concerned and did not publish this information. Jim Watson published his own.

There is no concrete policy about this within the academic community.

Dr McGuire then referenced the book, “The Immortal Life of Henrietta Lacks”. Henrietta Lacks was a poor African-American woman with ovarian cancer. At that time, in the 1950s, her cancer was considered “waste” and no release was needed as waste could be utilized for research. She was never informed or released anything, but then they were following the protocols of the time. From her cell line, the HeLa cell line, the first immortal cell line was created which ultimately generated a great deal of revenue for research institutes. The family however, remained impoverished. The genome was eventually fully sequenced and published. Henrietta Lacks granddaughter said that this was private family information and should never have been published without permission, even though all of the institutions followed all of the protocols in place.

So, aside from the original ethics issues stemming from the 1950s – who is relevant family? And how does or should this affect policy?

How does this affect genetic genealogy? Should the rules be different for genetic genealogy, assuming there are (will be) standard policies in place for medical genetics? Should you have to talk to family members before anyone DNA tests? Is genetic information different than other types of information?

Should biological relatives be consulted before someone participates in a medical research study as opposed to genetic genealogy? How about when the original tester dies? Who has what rights and interests? What about the unborn? What about when people need DNA sequencing due to cancer or another immediate and severe health condition which have hereditary components. Whose rights trump whose?

Today, the data protections are primarily via data base access restrictions.

Dr. Mcguire feels the way to protect people is through laws like GINA (Genomic Information Nondiscrimination Act) which protects people from discrimination, but does not reach to all industries like life insurance.

Is this different than people posting photos of family members or other private information without permission on public sites?

While much of Dr. McGuire’s focus in on medical testing and ethics, the topic surely is applicable to genetic genealogy as well and will eventually spill over. However, I shudder to think that someone would have to get permission from their relatives before they can have a Y-line DNA test. Yes, there is information that becomes available from these tests, including haplogroup information which has the potential to make people uncomfortable if they expected a different ethnicity than what they receive or an undocumented adoption is involved. However, doesn’t the DNA carrier have the right to know, and does their right to know what is in their body override the concerns about relatives who should (but might not) share the same haplogroup and paternal line information?

And as one person submitted as a question at the end of the session, isn’t that cat already out of the bag?

Session 2 – Dr. Miguel Vilar – Geno 2.0 Update and 2014 Tree

Dr. Vilar is the Science manager for the National Geographic’s Genographic Project.

“The greatest book written is inside of us.”

Miguel is a molecular anthropologist and science writer at the University of Pennsylvania. He has a special interest in Puerto Rico which has 60% Native mitochondrial DNA – the highest percentage of Native American DNA of any Caribbean Island.

The Genographic project has 3 parts, the indigenous population testing, the Legacy project which provides grants back to the indigenous community and the public participation portion which is the part where we purchase kits and test.

Below, Dr. Vilars discussed the Legacy portion of the project.

The indigenous population aspect focuses both on modern indigenous and ancient DNA as well. This information, cumulatively, is used to reconstruct human population migratory routes.

These include 72,000 samples collected 2005-2012 in 12 research centers on 6 continents. Many of these are working with indigenous samples, including Africa and Australia.

42 academic manuscripts and >80 conference presentations have come forth from the project. More are in the pipeline.

Most recently, a Science paper was published about the spread of mtDNA throughout Europe across the past 5000 years. More than 360 ancient samples were collected across several different time periods. There seems to be a divide in the record about 7000 years ago when several disappear and some of the more well known haplogroups today appear on the scene.

Nat Geo has funded 7 new scientific grants since the Geno 2.0 portion began for autosomal including locations in Australia, Puerto Rico and others.

Public participants – Geno 1.0 went over 500,000 participants, Geno 2.0 has over 80,000 participants to date.

Dr. Vilar mentioned that between 2008 and today, the Y tree has grown exponentially. That’s for sure. “We are reshaping the tree in an enormous way.” What was once believed to very homogenous, but in reality, as it drills down to the tips, it’s very heterogenous – a great deal of diversity.

As anyone who works with this information on a daily basis knows, that is probably the understatement of the year. The Geno 2.0 project, the Walk the Y along with various other private labs are discovering new SNPs more rapidly than they can be placed on the Y tree. Unfortunately, this has led to multiple trees, none of which are either “official” or “up to date.” This isn’t meant as a criticism, but more a testimony of just how fast this part of the field is emerging. I’m hopeful that we will see a tree in 2014, even if it is an interim tree. In fact, Dr. Vilars referred to the 2014 tree.

Next week, the Nat Geo team goes to Ireland and will be looking for the first migrants and settlers in Ireland – both for Y DNA and mitochondrial DNA. Dr. Vilars says “something happened” about 4000 years ago that changed the frequency of the various haplogroups found in the population. This “something” is not well understood today but he feels it may be a cultural movement of some sort and is still being studied.

Nat Geo is also focused on haplogroup Q in regions from the Arctic to South America. Q-M3 has also been found in the Caribbean for the first time, marking a migration up the chain of islands from Mexico and South America within the past 5,000 years. Papers are coming within the next year about this.

They anticipate that interest will double within the next year. They expect that based on recent discoveries, the 2015 Y tree will be much larger yet. Dr. Michael Hammer will speak tomorrow on the Y tree.

Nat Geo will introduce a “new chip by next year.” The new Ireland data should be available on the National Geographic website within a couple of weeks.

They are also in the process up updating the website with new heat maps and stories.

Session 3 – Matt Dexter – Autosomal Analyses

Matt is a surname administrator, an adoptee and has a BS in Computer Science. Matt is a relatively new admin, as these things go, beginning his adoptive search in 2008.

Matt found out as a child that he was adopted through a family arrangement. He contacted his birth mother as an adult. She told him who his father was who subsequently took a paternity test which disclosed that the man believed to be his biological father, was not. Unfortunately, his ‘father’ had been very excited to be contacted by Matt, and then, of course, was very disappointed to discover that Matt was not his biological child.

Matt asked his mother about this, and she indicated that yes, “there was another guy, but I told him that the other guy was your father.’ With that, Matt began the search for his biological father.

In order to narrow the candidates, his mother agreed to test, so by process of elimination, Matt now knows which side of his family his autosomal results are from.

Matt covers how autosomal DNA works.

This search has led Matt to an interest in how DNA is passed in general, and specifically from grandparents to grandchildren.

One advantage he has is that he has five children whose DNA he can then compare to his wife and three of their grandparents, inferring of course, the 4^th grandparent by process of elimination. While his children’s DNA doesn’t help him identify his father, it did give him a lot of data to work with to learn about how to use and interpret autosomal DNA. Here, Matt is discussing his children’s inheritance.

Session 4 – Jeffrey Mark Paul – Differences in Autosomal DNA Characteristics between Jewish and Non-Jewish Populations and Implications for the Family Finder Test

Dr.Jeffrey Paul, who has a doctorate in Public Health from John Hopkins, noticed that his and his wife’s Family Finder results were quite different, and he wanted to know why. Why did he, Jewish, have so many more?

There are 84 participants in the Jewish project that he used for the autosomal comparison.

What factors make Ashkenazi Jews endogamous. The Ashkenazi represent 80%of world’sJewish population.

Arranged marriages based on family backgrounds. Rabbinical lineages are highly esteemed and they became very inbred with cousins marrying cousins for generations.

Cultural and legal restrictions restrict Jewish movements and who they could marry.

Overprediction, meaning people being listed as being cousins more closely than they are, is one of the problems resulting from the endogamous population issue. Some labs “correct” for this issue, but the actual accuracy of the correction is unknown.

Jeffrey compared his FTDNA Family Finder test with the expected results for known relatives and he finds the results linear – meaning that the results line up with the expected match percentages for unrelated relatives. This means that FTDNA’s Jewish “correction” seems to be working quite well. Of course, they do have a great family group with which to calibrate their product. Bennett’s family is Jewish.

Jeffrey has downloaded the results of group participants into MSAccess and generates queries to test the hypothesis that Jewish participants have more matches than a non-Jewish control group.

The Jewish group had approximately a total of 7% total non-Ashkenazi Jewish in their Population Finder results, meaning European and Middle Eastern Jewish. The non-Jewish group had almost exactly the opposite results.

Jewish people have from 1500-2100 matches.
Interfaith 700-1100 (Jewish and non)
NonJewish 60-616

Jewish people match almost 33% of the other Jewish people in the project. Jewish people match both Jewish and Interfaith families. NonJewish families match NonJewish and interfaith matches.

Jeffrey mentioned that many people have Jewish ancestry that they are unaware of.

This session was quite interesting. This study while conducted on the Jewish population, still applies to other endogamous populations that are heavily intermarried. One of the differences between Jewish populations and other groups, such as Amish, Brethren, Mennonite and Native American groups is that there are many Jewish populations that are still unmixed, where most of these other groups are currently intermixed, although of course there are some exceptions. Furthermore, the Jewish community has been endogamous longer than some of the other groups. Between both of those factors, length of endogamy and current mixture level, the Jewish population is probably much more highly admixed than any other group that could be readily studied.

Due to this constant redistribution of Jewish DNA within the same population, many Jewish people have a very high percentage of distant cousin relationships.

For non-Jewish people, if you are finding match number is the endogamous range, and a very high number of distant cousins, proportionally, you might want to consider the possibility that some of your ancestors descend from an endogamous population.

Unfortunately, the photo of Dr. Paul was unuseable. I knew I should have taken my “real camera.”

Session 5 – Finding Your Indian Prince(ss) Without Having to Kiss Too Many Frogs

This was my session, and I’ll write about it later.

Someone did get a photo, which I’ve lifted from Jennifer Zinck’s great blog (thank you Jennifer), Ancestor Central. In fact, you can see her writeup for Day 1 here and she is probably writing Day 2’s article as I type this, so watch for it too.

Session 6 – Roundtable – Y-SNPs, hosted by Roberta Estes, Rebekah Canada and Marie Rundquist

At the end of the day, after the breakout sessions, roundtable discussions were held. There were several topics. Rebekah Canada, Marie Rundquist and I together “hostessed” the Y DNA and SNP discussion group, which was quite well attended. We had a wide range of expertise in the group and answered many questions. One really good aspect of these types of arrangements is that they are really set up for the participants to interact as well. In our group, for example, we got the question about what is a public versus a private SNP, and Terry Barton who was attending the session answered the question by telling about his “private” Barton SNPs which are no longer considered private because they have now been found in three other surname individuals/groups. This means they are listed on the “tree.” So sometimes public and private can simply be a matter of timing and discovery.

Here’s Bennett leading another roundtable discussion.

Session 7 – Dr. David Mittleman

Dr. Mittleman has a PhD in genetics, is a professor as well as an entrepreneur. He was one of the partners in Arpeggi and came along to Gene by Gene with the acquisition. He seems to be the perfect mixture of techie geek, scientist and businessman.

He began his session by talking a bit about the history of DNA sequencing, next generation sequencing and a discussion about the expectation of privacy and how that has changed in the past few years with Google which was launched in 2006 and Facebook in 2010.

David also discussed how the prices have dropped exponentially in the past few years based on the increase in the sophistication of technology. Today, Y SNPs individually cost $39 to test, but for $199 at Nat Geo you can test 12,000 Y SNPs.

The WTY test, now discontinued tsted about 300,000 SNPs on the Y. It cost between $950 (if you were willing to make your results public) and $1500 (if the results were private,)

Today, the Y chromosome can be sequenced on the Illumina chip which is the same chip that Nat Geo used and that the autosomal testing uses as well. Family Tree DNA announced their new Big Y product that will sequence 10 million positions and 25,000 known SNPs for an introductory sale price of $495 for existing customers. This is not a test that a new customer would ever order. The test will normally cost $695.

ISOGG Reception

The ISOGG reception is one of my favorite parts of the conference because everyone comes together, can sit in groups and chat, and the “arrival” adrenaline has worn off a bit. We tend to strategize, share success stories, help each other with sticky problems and otherwise have a great time. We all bring food or drink and sometimes pitch in to rent the room. We also spill out into the hallways where our impromptu “meetings” generally happen. And we do terribly, terribly geeky things like passing our iPhones around with our chromosome painting for everyone to see. Do we know how to party or what???

Here’s Linda Magellan working hard during the reception. I think she’s ordering the Big Y actually. We had several orders placed by admins during the conference.

We stayed up way too late visiting and the ISOGG meeting starts at 8 AM tomorrow!

Ancestor of Native Americans in Asia was 30% “Western Eurasian”

Posted on October 25, 2013 by Roberta Estes

The complete genome has recently been sequenced from 4 year old Russian boy who died 24,000 years ago near Lake Baikal in a location called Mal’ta, the area in Asia believed to be the origin of the Native Americans based on Y DNA and mitochondrial chromosome similarities. The map below, from Science News, shows the location.

This represents the oldest complete genome ever sequenced, except for the Neanderthal (38,000 years old) and Denisovan (41,000 years old).

This child’s genome shows that he is related closely to Native Americans, and, surprisingly, to western Asians/eastern Europeans, but not to eastern Asians, to whom Native Americans are closely related. This implies that this child was a member of part of a “tribe” that had not yet merged or intermarried with the Eastern Asians (Japan, China, etc.) that then became the original Native Americans who migrated across the Beringian land bridge between about 15,000 and 20,000 years ago.

One of the most surprising results is that about 30% of this child’s genome is Eurasian, meaning from Europe and western Asia, including his Y haplogroup which was R and his mitochondrial haplogroup which was U, both today considered European.

This does not imply that R and U are Native American haplogroups or that they are found among Native American tribes before European admixture in the past several hundred years. There is still absolutely no evidence in the Americas, in burials, for any haplogroups other than subgroups of Q and C for males and A, B, C, D, X and M (1 instance) for females. However, that doesn’t mean that additional evidence won’t be found in the future.

While this is certainly new information, it’s not unprecedented. Last year, in the journal Genetics, an article titled “Ancient Admixture in Human History” reported something similar, albeit gene flow in a different direction. This paper indicated gene flow from the Lake Baikal area to Europe. It certainly could have been bidirectional, and this new paper certainly suggests that it was.

So in essence, maybe there is a little bit of Native American in Europeans and a little bit of European in Native Americans that occurred in their deep ancestry, not in the past 500-1000 years.

What’s next? Work continues. The team is now attempting to sequence genomes from other skeletons from west of Mal’ta, East Asia and from the Americas as well.

You can read the article in Science Magazine. An academic article presenting their findings in detail will be published shortly in Nature.

A Podcast with Michael Balter can be heard here discussing the recent discovery.

Ethnicity Results – True or Not?

Posted on October 4, 2013 by Roberta Estes

205

I can’t even begin to tell you how many questions I receive that go something like this:

“I received my ethnicity results from XYZ. I’m confused. The results don’t seem to align with my research and I don’t know what to make of them?”

In the above question, the vendors who are currently offering these types of results among their autosomal tests are Family Tree DNA, 23andMe and Ancestry along with National Geographic who is a nonprofit. Of those four, by far, Ancestry is the worst at results matching reality and who I receive the most complaints and comments about. I wrote an article about Ancestry’s results and Judy Russell recently wrote an article about their new updated results as did Debbie Kennett. My Ancestry results have not been updated yet, so I can’t comment personally.

Let’s take a look at the results from the four players and my own analysis.

Some years back, I did a pedigree analysis of my genealogy in an attempt to make sense of autosomal results from other companies.

This paper, Revealing American Indian and Minority Heritage Using Y-line, Mitochondrial, Autosomal and X Chromosomal Testing Data Combined with Pedigree Analysis was published in the Fall 2010 issue of JoGG, Vol. 6 issue 1.

The pedigree analysis portion of this document begins about page 8. My ancestral breakdown is as follows:

Geography	Percent
Germany	23.8041
British Isles	22.6104
Holland	14.5511
European by DNA	6.8362
France	6.6113
Switzerland	.7813
Native American	.2933
Turkish	.0031

This leaves about 25% unknown. However, this looks nothing like the 80% British Isles and the 12% Scandinavian at Ancestry.

Here are my current ethnicity results from the three major testing companies plus Genographic.

Ancestry

80% British Isles

12% Scandinavian

8% Uncertain

Family Tree DNA

75% Western Europe

25% Europe – Romanian, Russian, Tuscan, Finnish

23andMe (Standard Estimate)

99.2% European

0.5% East Asian and Native American

0.3% Unassigned

Genographic 2.0

Northern European – 43%

Mediterranean – 36%

Southwest Asian – 18%

Why Don’t The Results Match?

Why don’t the results match either my work or each other?

1. The first answer I always think of when asked this question is that perhaps some of the genealogy is incorrect. That is certainly a possibility via either poor genealogy research or undocumented adoptions. However, as time has marched forward, I’ve proven that I’m descended from most of these lines through either Y-line, mitochondrial DNA or autosomal matches. This confirms my genealogy research. For example, Acadians were originally French and I definitely descend from Acadian lines.

2. The second answer is time. The vendors may well be using different measures of time, meaning more recent versus deep ancestry. Geno 2.0 looks back the furthest. Their information says that “your percentages reflect both recent influences and ancient genetic patterns in your DNA due to migrations as groups from different regions mixed over thousands of years. Your ancestors also mixed with ancient, now extinct hominid cousins like Neanderthals in Europe and the Middle East of the Denisovans in Asia.”

It’s difficult to determine which of the matching populations are more recent and which are less recent. By way of example, many Germans and others in eastern Europe are descendants of Genghis Khan’s Mongols who invaded portions of Europe in the 13^th century. So, do we recognize and count their DNA when found as “German,” “Polish,” “Russian,” or “Asian?” The map below shows the invasions of Genghis Khan. Based on this, Germans who descend from Genghis’s Mongols could match Koreans on those segments of DNA. Both of those people would probably find that confusing.

3. The third answer is the reference populations. Here is what National Geographic has to say: “Modern day indigenous populations around the world carry particular blends of these regions. We compared your DNA results to the reference populations we currently have in our database and estimated which of these were most similar to you in terms of the genetic markers you carry. This doesn’t necessarily mean that you belong to these groups or are directly from these regions, but that these groups were a similar genetic match and can be used as a guide to help determine why you have a certain result. Remember, this is a mixture of both recent (past six generations) and ancient patterns established over thousands of years, so you may see surprising regional percentages.”

Each of the vendors has compiled their own list of reference populations from published material, and in the case of National Geographic, as yet unpublished material as well.

If you read the fine print, some of these results that at first glance appear to not match actually do, or could. For example, Southwest Asia (Geno 2.0) could be Russia (Family Tree DNA) or at least pointing to the same genetic base.

This video map of Europe through the ages from 1000AD to present will show the ever changing country boundaries and will quickly explain why coming up with labels for ethnicity is so difficult. I mean, what exactly does “France” or “Germany” mean, and when?

4. The fourth answer is focus. Each of these organizations comes to us as a consumer with a particular focus. Of them, one and only one must make their way on their own merits alone. That one is Family Tree DNA. Unlike the Genographic Project, Family Tree DNA doesn’t have a large nonprofit behind them. Unlike 23andMe, they are not subsidized by the medical community and venture capital. And unlike Ancestry.com, Family Tree DNA is not interested in selling you a subscription. In fact, the DNA market could dry up and go away for any of those three, meaning 23andMe, National Geographic and Ancestry, and their business would simply continue with their other products. To them, DNA testing is only a blip on a spreadsheet. Not true for Family Tree DNA. Their business IS genetic genealogy and DNA testing. So of all these vendors, they can least afford to have upset clients and are therefore the most likely to be the most vigilant about the accuracy of their testing, the quality of the tools and results provided to customers.

My Opinion

So what is my personal opinion on all of this?

I think these ethnicity results are very interesting. I think in some way all of them are probably correct, excluding Ancestry. I have absolutely no confidence in Ancestry’s results based on their track record and history, lack of tools, lack of transparency and frustratingly poor quality.

I think that as more academic papers are published and we learn more about these reference populations and where their genes are found in various populations, all of these organizations will have an opportunity to “tighten up” their results. If you’ll notice, both Ancestry and Family Tree DNA still include the words “beta.” The vendors know that these results are not the end all and be all in the ethnicity world.

Am I upset with these vendors? Aside from Ancestry who has to know they have a significant problem and has yet to admit to or fix it, no, I’m not. Frustrated, as a consumer, yes, because like all genealogists, I want it NOW please and thank you!!!

Without these kinds of baby steps, we will never as a community crawl, walk, or run. I dream of the day when we will be able to be tested, obtain our results, and along with that, maybe a list of ancestors we descend from and where their ancestors originated as well. So, in essence, current genealogy (today Y-line and mtdna), older genealogy (autosomal lines) and population genetics (ethnicity of each line).

So what should we as consumers do today? Personally, I think we should file this information away in the “that’s interesting” folder and use it when and where it benefits us. I think we should look at it as a display of possibilities. We should not over-interpret these results.

There is perhaps one area of exception, and that is when dealing with majority ethnic groups. By this, I mean African, Asian, Native American and European. For those groups, this type of ethnicity breakdown, the presence or absence of a particular group is more correct than incorrect, generally. Very small amounts of any admixture are difficult to discern for any vendor. For an example of that, look at my Native percentages and some of those are proven lines. For the individual who wants more information, and more detail into the possibilities, I wrote about how to use the raw autosomal data outside of the vendors tools, at GedMatch, to sort out minority admixture in The Autosomal Me series.

Perhaps the Genographic Project page sums it up best with their statement that, “If you have a very mixed background, the pattern can get complicated quickly!” Not only is that true, it can be complicated by any and probably all of the factors above. When you think about it, it’s rather amazing that we can tell as much as we can.

Autosomal DNA, Ancient Ancestors, Ethnicity and the Dandelion

Posted on August 5, 2013 by Roberta Estes

Understanding our own ancient DNA is a little different than contemporary DNA that we use for genealogy, but it’s a continuum between the two with a very long umbilical cord between them, then, and now. And just when you think you’re about to understand autosomal DNA transmission and how it works, the subject of ancient DNA comes up. This is particularly perplexing when all you wanted in the first place was a simple answer to the question, “who am I and who were my ancestors?” Well, as you’re probably figured out by now, there is no simple answer.

Inheritance

In a nutshell – we know that every generation gets divided by 50% when we’re talking about autosomal DNA transmission.

So you inherit 50% of the DNA of each of your parents. They inherited 50% of the DNA of each of their parents, so you inherit ABOUT 25% of the DNA of each of your grandparents.

Did you see that word, about? It’s important, because while you do inherit exactly 50% of the DNA of each parent, you don’t inherit exactly 25% of the DNA of each grandparent. You can inherit a little less or a little more from either grandparent as your parents 50% that you’re going to receive is in the mixer.

This is also true for the 12.5% of each of your great-grandparents, and the 6.25% of each of your great-great-grandparents, and so forth, on up the line.

The chart below shows the percentages that you share from each generation.

Relationship to You	Approximate % Of Their DNA You Share
Parents	Exactly 50%
Grandparents	25
Great-grandparents	12.5
Great-great-grandparents	6.25
Great-great-great-grandparents	3.125
Great-great-great-great-grandparents	1.5625

Ethnicity

So, here’s the question posed by people trying to understand their ethnicity.

If I have 3% Melanesian (or Middle Eastern, Indo-Tibetan or fill-in-the-blank ethnicity), doesn’t that mean that one of my great-great-great-grandparents was Melanesian?

There are really two answers to this question. (I can hear you groaning!!!)

If the amount is 25% (for example) and not very small amounts, then the answer would be yes, that is very likely what this is telling you. Or maybe it’s telling you that you have two different great-grandparents who have 12.5 each – but those relatives are fairly close in time due to the amount of DNA that came from that region. See, that was easy.

However, the answer changes when we’re down in the very small percentages, below 5%, often in the 1 and 2% range. This answer isn’t nearly as straightforward.

The Dandelion – Your Ancestor

The answer is the dandelion.

The dandelion is one of your ancestors who lived in the Middle East, let’s say, 20,000 years ago, maybe 30,000 years ago. In case you’re counting generations, that is 800 to 1200 generations ago. The percentage of DNA you would carry from a single ancestor who lived 20,000 years ago, assuming you only descended from that ancestor 1 time, is infinitesimally small. There are more zeroes following that decimal point than I have patience to type. Let’s call that ancestor Xenia and let’s say she is a female.

However, you did inherit DNA from many of your ancestors who lived 20,000 years ago, thousands of them, because all of them, through their descendants, make up the DNA you carry today. So infinitesimally small or not, you do carry some of the DNA of some of those ancestors. It’s just broken into extremely small pieces today and their individual contributions to you may be extremely small. You don’t carry any DNA from some of them, actually, probably most of them, due to the recombination event, dividing their DNA in half, happening 800 times, give or take.

Now, given that your ancestors’ DNA is divided in every generation by approximately half, and we know there are about 3 billion base pairs on all of your chromosomes combined, this means that by generation 32 or 33, on average, you carry 1 segment from this ancestor. By generation 45, you carry, on average, .00017 segments of this ancestor’s DNA. And for those math aficionados among us, this is the mathematical notation for how much of our ancestor’s DNA we carry after 800 generations: 4.4991E-232.

But, we also know that this dividing in half, on the average, doesn’t always work exactly that way in reality, because some of those ancestors from 20,000 years ago did in fact pass their DNA to you, despite the infinitesimal odds against that happening. Some of their DNA was passed intact generation after generation, to you, and you carry it today. The DNA contributed by any one ancestor from 800 generations ago is probably limited to one or two locations, or bases, but still, it’s there, and it’s the combined DNA of those ancient ancestors that make us who we are today.

The autosomal DNA of any specific ancestor from long ago is probably too small and fragmented to recognize as “theirs” and attribute to them. Of course, the beauty of Y DNA and mitochondrial is that it is passed in tact for all of those generations. But for autosomal DNA and genealogy, we need hundreds of thousands of DNA pieces in a row from a particular ancestor to be recognizable as “theirs.” When we measure DNA for genealogy, what we are measuring is both centiMorgans, a measure of distance between chromosome positions (length) and the number of contiguous SNP (Single Nucleotide Polymorphism) base locations that match (quantity). The values from these calculations tells us how closely we are related to people, because remember, DNA is divided in each generation so there is a mathematically predictable amount we will share with specific relatives.

Here is an example from a Family Finder comparison table showing both centiMorgans and matching SNPs with a second cousin.

The matching threshold for genealogical significance is either 5 or 7 cM depending on which of the major companies you are using. At Family Tree DNA, if you match above the threshold, then you can view down to 1cM, which is the case above. Another match criteria is the number of SNPs, or locations, matching contiguously. Anything below about 500-800 is considered to be a population match, not a genealogical match, unless you also have a significant number of genealogical matches at higher cMs and segments with this person.

OK, where is all of this going?

Dispersion

Think of your ancestor 20,000 years ago as the dandelion. Now, blow.

Xenia lived in the Middle East. Where might her descendants land, over time, with every new generation? In Europe? In Asia? In India? In America via the Native Americans through Asia? In North Africa? Where?

So let’s say that groups of descendants settle across the globe. Let’s say that her mitochondrial haplogroup is X. Yes, haplogroup X is found both in Europe and in Asia and in the Native Americans, so this is actually a good example. So Xenia carried mitochondrial haplogroup X and we know for sure via mitochondrial DNA testing that indeed, Xenia’s seeds were scattered to all of the winds. The only place we haven’t found Xenia’s children is in Subsaharan Africa and the Australian archipelago, at least not yet.

Ok, so now that we know where her children and their children went, let’s go back to ancient DNA.

Predictive DNA

The way ethnicity is determined is by studying the frequency with which a specific allele or group of alleles is found in any particular population. Two “pure” examples come to mind.

The first example is the Duffy Null allele that is only found in the Subsaharan African populations. Currently this marker is found in about 68% of American blacks and in 88-100% of African blacks. If you have the Duffy Null allele, you have African heritage. Of course, you don’t know which line or which ancestor it came from, or how far back in time, but it assures you that you do in fact have African heritage. It could have been from an ancestor long ago. It could have been very recent. This is one of the factors considered when determining percentage of ethnicity.

A second example is the STR marker known as D9S919 which is present in about 30% of the Native American people. The value of 9 at this marker is not known to be present in any other ethnic group, so this mutation occurred after the Native people migrated across Beringia into the Americas, but long enough ago to be present in many descendants. There is also no other known marker that is only found only among Native Americans, although I expect as we move into full genome sequencing we will discover more. You can test this marker individually at Family Tree DNA, which is the only lab that offers this test. If you have the value of 9 at this marker, it confirms Native heritage, but if you don’t carry 9, it does NOT disprove Native heritage. After all, many Native people don’t carry it. Again, you don’t know how long ago this marker was introduced into your ancestry.

These two examples are very unique because the markers are found only in certain groups. Generally, with the rest of the DNA values, they are found in different amounts, or frequencies, in different parts of the world and ethnic groups.

So, if you’re trying to determine the ethnicity of an individual, you’re going to compile a huge data base of percentages of DNA values found of Ancestrally Informative Markers (AIMs) in different parts of the world.

So, you would compare the participant’s values against your data base and you will come up with those regions or ethnicities that are present most often in your comparison. This is exactly what the products and services that provide you with your ethnicity percentages do – and how accurate the results are depend highly on the data base itself, the amount of data, and the quality of data. Dare I mention Ancestry’s issue that they’ve had since they first began offering their autosomal product over a year ago where everyone seems to have Scandinavian ancestry? Ancestry doesn’t share with us their sources, so as a community we have no idea how they have come up with these numbers.

You can easily compare your autosomal results in nauseating detail at both 23andMe and Family Tree DNA by testing with both companies, or by testing with either 23andMe or Ancestry and transferring your autosomal results to Family Tree DNA. All 3 of these companies will give you a somewhat different result, but they should be in the same ballpark. You can also then download your raw data file from any of those vendors and upload it to www.gedmatch.com where you can then do ethnicity comparisons using a variety of tools. These tools, an example shown below, will have much more variance and detail than the vendor’s tools or results. And because of that, they tend to be more confusing as well.

Many people with small amounts of minority admixture are disappointed with the results through the vendors, especially if their Native American admixture doesn’t show. I wrote extensively about this in my series, The Autosomal Me, so I won’t rehash it here, but using the GedMatch tools is very enlightening, as you can see above with my results. And do I really have Indo-Tibetan and Indo-Iranian ancestors?

Where’s Xenia?

Back to Xenia and her descendants. Let’s say that Xenia’s descendants settled in four primary locations. One is in the Middle East – they never left home. One is in Asia and from there, to the Americans to become the Native Americans and lastly, to Europe. Now let’s say there is a pocket of them in the Altai region of Asia and a pocket in France. The Altai is the ancestral home of the Native Americans and could explain the Indo-Tibet result, above. We’ll call that Central Asia. And France is where my Acadian ancestors were from. Hmmm….this is getting confusing. To make matters even more confusing, I might well descend from both groups, who originally descended from Xenia.

Let’s say that I do in fact carry small segments of Xenia’s DNA. Now let’s say that this same DNA is found in a group of people in Central Asia, maybe in Tibet, it’s published in an obscure journal someplace, and it finds its way into a data base. Voila – there you go – I now have a match in Central Asia in a place called Indo-Tibet. But do I really?

Does this mean that my ancestor was from Central Asia? Not necessarily. And if so, maybe not recently, but the people from that location for some reason share some of the DNA that I carry. The question of course is why, how and when?

What this really means to you is a matter of degrees. If you have a few matches from obscure regions, along with very small percentages, it is likely a result of the dandelion’s dispersion. If you have a lot of matches, meaning a high percentage hit rate, from a particular region, pay attention, it probably has some genealogical significance.

It’s no wonder people are confused by this! Now, just think how many dandelions you have. In 15 generations, you have 32,768 ancestors. In fact, this is how we know for sure that we all descend from the same ancestor multiple times. Our number of ancestors quickly exceeds the world population. In 30 (25 years) generations, in about the year 1263, we reach about 1 billion ancestors. In 1750, there were 791 million people on Earth, in 1600, 580 million, in 1500, 458 million and in 1000, 310 million.

We know that we very likely descend several times from a much smaller group of ancestors from isolated local populations. However, just looking at the 32,000+ ancestors in 15 generations, it’s still an entire dandelion field!!!

Ancient DNA Analysis From Canada

Posted on July 4, 2013 by Roberta Estes

Recently a new academic paper focused on Native American ancestry hit the news. Ripan Malhi’s molecular anthropology and ancient DNA lab at the University of Illinois, shown above, in Urbana, Illinois has successfully extracted DNA from remains of individuals whose bones were found in an ancient trash heap in British Columbia and has successfully matched the DNA with living people today, confirming of course that today’s people were related to these ancient people and are a part of the same base population that lived there 5000-6000 years ago and remains today.

Ripan’s paper, “Ancient DNA Analysis of Mid-Holocene Individuals from the Northwest Coast of North America Reveals Different Evolutionary Paths for Mitogenomes” discusses this in detail. If you’re not up to this level of detail, a nice article in LiveScience covers the discovery as well.

Ripan has successfully connected the dots between the fossilized remains and currently living members of several Native tribes local to the region where the bones were found.

As part of this study, three new mitochondrial haplogroups were discovered in the Native population. Two haplogroups, A2ag and A2ah are found alive and well today. However, another, D4h3a7 has only been found one other time, in remains found in a cave in Alaska, and may have gone extinct. It has not been found in living people to date, although a lot of people have yet to be tested.

The area where the remains were found is indigenous to the Tsimshian, Haida and Nisga’a tribes.

Today, local tribes are participating in additional research with Dr. Malhi in order to better understand their ancestry and to see if the genetic data supports their extensive oral history which suggests multiple migration waves from Asia into the Americas within the past 5000 years.

King Richard, Is That You???

Posted on February 4, 2013 by Roberta Estes

The newsworld is abuzz today with the news that skeletal remains found a few months ago under a parking lot in Leicester are indeed those of England’s King Richard the Third who was killed in the Battle of Bosworth Field in 1485. He was hastily buried by the Greyfriars friars, but the associated church is long gone and the location forgotten. The parking lot inadvertently covered the cemetery which included, ironically, King Richard III. He was buried without a coffin or shroud in a shallow grave. His skull is shown below, courtesty of the University of Leicester.

Of course, for the genetic genealogy community, the exciting part of this is that DNA evidence is a prime piece of the puzzle proving his identification, along with bone analysis of his known scoliosis.

The mitochondrial DNA of the remains matches that of Michael Ibsen, a Canadian cabinetmaker and direct maternal descendant of Richard’s sister, Anne of York.

Be sure to watch the video that accompanies this news article.

Debbie Kennett, a British genetic genealogy blogger has been following these developments closely and has done a wonderful writeup complete with the backstory and discovery. In addition, she has compiled a nice list of resources for those interested.

Family Tree DNA Conference 2012 – Native American Focus Meeting

Posted on November 12, 2012 by Roberta Estes

Wow. Talk about drinking from a firehose. From the minute we arrived in the lobby Friday afternoon until we got back to the airport Sunday evening, we barely had time to breathe.

This was an amazing conference in many ways. I’ll try to hit the high points in a separate blog, but in this posting, I want to cover the Native American Focus meeting and talk a little bit about the interests of the different attendees.

The first event, at 4 on Friday afternoon, was a small meeting of people who are admins or have a specific interest in Native American heritage. Rebekah Canada, haplogroup Q project administrator, coordinated this meeting and a hearty thank you goes to her for her efforts. We have never attempted this type of event before, and we all agreed, we need to do it again.

Unfortunately, many projects that are focused on or include Native results did not have a project administrator here and were not represented.

Peter Roberts is the administrator of the Bahamas project. The Bahamas are rich with Native history, but evidence they existed in the DNA record is slim. The Lucayan Indians were removed from the Island by the Spanish. While we know they existed, their results, surprisingly, are not showing up directly in the yline or mtdna results. We also know that some Seminoles arrived later from Florida and others came from the mainland as well. Low levels of Native heritage are showing up in autosomal testing.

David Pike discovered his Native heritage quite by accident. His father turned out to be 3.4% Native. He believes it is probably MicMac (Mi’kmaq) or perhaps Beothuk, a now extinct tribe, in Newfoundland, but is still researching. Dave mentioned an opportunity for tribal membership in Canada for those who can prove Micmac heritage and will be providing that information. I will blog it when that arrives.

Marie Rundquist is the administrator of the AmerIndian Ancestors out of Acadia project which began in 2006. I love this project, somewhat from a selfish perspective, since I’ve connected so many of my Acadian ancestors, and Native ancestors, through this project. This is also one the most successful mitochondrial DNA projects, if not the most successful, there is. Marie’s project has served to prove or disprove several Native rumors, and has found other Native people quite by accident. She wrote a book, titled Revisiting Anne Marie and I’ve blogged about her success with the Doucet results. This project is not just for Acadians in Canada, but reaches to Louisiana, and families with Acadian heritage outside of the primary relocation areas.

Kathy Johnson’s cousin came back with a haplogroup Q results. Subsequent testing revealed 4 new SNPS in her sample. This Pembrook family is believed to be from the Mohawk River area in New York.

Georgia and Tom Bopp, administrators of the Hawaii project, from Hawaii, attended. Frankly, I had never thought about them and Native ancestry, but certainly Hawaii did have a Native population. They had a very interesting situation where one of their early tester’s mitochondrial results came back as haplogroup B. They were told they were Native American, then they were told they were Polynesian. Native was reasonable, but Polynesian somewhat confounding given that their ancestor was a slave in Maryland. Eventually, it was discovered their maternal ancestor was from Matagascar. Georgia will send the information and we’ll do a blog about this in the future. How very interesting.

Rob and Dyann Noles administer the Lumbee Tribe and Wiregrass Georgia projects. Rob maintains a data base of over 250,000 individuals related to these projects. While the Lumbee project is named as such, it is not endorsed by the Lumbee tribe itself. However, numerous individuals descended from those who are early tribal founders have tested.

As haplogroup Q project administrator, Rebekah has been instrumental in the ongoing testing of haplogroup Q individuals. Many members have been SNP tested and more than a few have participated in the WTY (Walk the Y)) which has resulted in many new haplogroup subgroups being discovered. We’ve made more progress in the past two years than in the previous 10 in haplogroup Q. Someday, I hope we’ll be able to identify at least members of different Native language groups by results. Maybe I’m dreaming here, but goals are good!

I shared my work with the Native Heritage project and my ongoing transcriptions into the Native Names data base. We now have over 8,000 different surnames and well over 30,000 people, and I’m no place near “done.” Of course, it’s always a great day when I find a proven Native surname of someone who has tested Native in our haplogroup Q project.

We discussed the reluctance of recognized tribes to test and their concerns. We all respect their decisions, although from a genetic genealogy perspective, we are glad when descendants test.

I suspect that many of the Native genetic lines have become extinct. The Native people, aside from having to survive in a harsh, cold climate upon arriving from Asia, have had to endure multiple genocidal attempts (Native as well as European) in addition to many epidemics. Some epidemics wiped out entire tribes. In 1838, a smallpox epidemic took half of the powerful Cherokee. No one was immune. That combined with intermarriage, assimilation, and adoption through either traditional cultural means or kidnapping have caused the “Native” DNA results to not always be what we expect.

We are hopeful that ancient DNA will shed a light on extinct lines as well as answer the ever-present question about whether European or perhaps African DNA was present in the Native population before the traditional dates of European contact

I want to thank everyone who attended for their participation and sharing, and encourage anyone else who is interested to let either Rebekah or I know.

The Malhi Molecular Anthropology and Ancient DNA Labs

Posted on September 22, 2012 by Roberta Estes

I’ve known Ripan Malhi for years now, but until this past week, I had never met him in person. Dr. Malhi attempted to extract the DNA from both a stamp, supposedly licked by my grandfather, and my father’s hair, complete with follicle. I could hardly wait those long days to determine if any DNA was present. I tried not to pester him, but I felt like the proverbial child constantly asking “are we there yet?”

Unfortunately, none of the multiple attempts were successful, but they established a relationship between Ripan and myself. Ripan and I were trying to figure out this week just how long ago that was and we think it was about 10 years. We know it was more than 7 years, since he has been at the University of Illinois since 2006 where he established the Malhi Labs, and it was significantly prior to that.

After finishing his PhD, Ripan founded a company called Trace Genetics. It was there that I first met Ripan. They specialized in ancient DNA processing. A few years later, in 2006, Ripan sold that company and established both the Malhi Ancient DNA Lab and the Malhi Molecular Anthropology Lab at the University of Illinois where he is an Associate Professor.

Ripan has a long list of publications to his credit. It won’t surprise you to discover that Native American and ancient DNA are both areas in which he specializes, and in particular, ancient Native American DNA.

The Malhi Molecular Anthropology Laboratory generates DNA variation data from different genetic systems (i.e. mitochondrial genome, Y chromosome, autosomal) to infer evolutionary history of populations and species. Currently, research in the lab is split into two independent research areas, the evolutionary history of Native Americans and evolutionary genetics of non-human primates in the areas of:

Molecular Anthropology
Ancient DNA Analysis
Evolutionary Genomics
Forensic Science
Population Genetics

Dr. Malhi was very gracious during my visit to the University of Illinois and agreed to show me both of his labs. Not only that, he came to the Native American House to get me so that I wouldn’t get lost navigating the campus and delivered me back as well. For that, I’m extremely grateful! A campus with 40,000 students isn’t a campus, it’s a city and parking is almost non-existent!

First we visited the Ancient DNA Lab. This lab is separate from the rest of the processing, and is actually in a different building altogether. Access is extremely limited and only those who need to go inside, do. I’m not one of those people.

Why such limited access? In a word, contamination, the arch-nemesis of ancient DNA processing. Ancient DNA, by definition is old, degraded and generally in short supply. The process of extracting it from whatever medium you are working with, teasing out whatever is left, without introducing any outside contamination, is tricky at best. Limiting the exposure in the room itself is the first step in a series of protocols designed to limit, prevent and then identify contamination if it exists.

The room is double air locked and pressurized so that when someone enters or exists the air is blown out and none of the surrounding air enters the lab.

The room itself can accommodate two researchers. The window is tinted yellow as the lighting is also controlled within the lab. So if these photos look yellow, it’s because they are.

You can see the DNA extraction area in this photo. Work is done inside a cubicle, again, to limit contamination. You can see the mortar and pestle used to sometimes grind the materials. Other times, such as with teeth, drills are used.

After the DNA is extracted and amplified, assuming DNA is found, and it’s not contaminated, the results are then taken to the second lab, down the street, for processing.

This is the Molecular Anthropology lab where most of the people work, since they deal only with already extracted ancient DNA or contemporary DNA.

Contemporary DNA is considered a medical hazard while the DNA is still in a body fluid of some type (saliva, blood, cheek swab), so medical precautions must be taken. In many ways, this lab looks just like a lab at a medical facility. In fact, it’s in the Medical Sciences building.

DNA is extracted from contemporary samples in this work area. After extraction, it is no longer considered a medical hazard, so from that point forward, only normal lab protocols are in force, not medical biohazard protection.

The DNA is then further processed in this area. Ripan discussed some of his current projects as we toured. He continues his work on Native American population genetics, and in particular, the migration and settlement of the Native people on this continent. Currently he collaborates with Canadian tribes and is involved with an ongoing project to analyze the remains of several hundred Native burials that have previously been discovered.

Not only does he work with Native population genetics, and remains, but he also encourages Native American students to join his programs and work in the labs. He works closely with the Native American House.

I’m hopeful that Ripan’s projects and ongoing analysis will bring some answers to questions like whether or not mitochondrial haplogroup X is found in any tribes west of the St. Lawrence Seaway (inferring that it did come from Asian, not Europe), whether haplogroup M is found in the founding Native population and whether European or African haplogroups of any description are found pre-Columbian contact in the Americas.

I want to thank Dr. Malhi for his hospitality, for making time for the tour this week, and to wish him Godspeed in his continuing research. And yes, that does mean I want him to hurry. That hasn’t changed in the past decade!
