Genographic Project Participants Help Refine Human Family Tree

The Genographic Project recently released the most refined evolutionary tree of the human Y chromosome, which every male inherits directly from his father. The new Y tree was created in part through the help of the 300,000 male participants that have joined this one-of-a-kind project to trace their own ancestry and become citizen scientists.

As more people participate in the Genographic Project, we are able to fill in branches and gaps on the entire human family tree, and gain new insights on our ancient past. We wanted to outline how this new tree affects our understanding of our shared ancestry, and what it means for current and future project participants.

Why should I be excited about the new tree?

Each human male carries a series of DNA mutations in his Y chromosomes that records a portion of the story of humanity. The story begins with a common ancient ancestor that lived in East Africa more than 150,000 years ago. The paternal tree, or “Y tree,” is a map that illustrates this deep-rooted relationship, and how billions of his descendants have expanded around the world. During that expansion, these descendants acquired and maintained mutations or changes in their DNA that occurred at particular times and places. The new Y tree illustrates the progressions of these known mutational events showing the many ways all people are related. The new tree is particularly exciting if you are a male and a Genographic Project participant, since you will see that your own results are now even further refined!

How did Genographic Project Participants help create the new Y tree?

The Geno 2.0 DNA Ancestry Kit invites participants to test their own ancient ancestry by submitting a DNA sample to the project. Participants can then choose to opt into Genographic Project scientific research to have their DNA results compared to those of thousands of other participants. When comparing the DNA, Genographic scientists look for changes or mutations in participants’ results that help determine when new lineages may have begun. Since changes accumulate over time, a large number of differences between two DNA samples would indicate the two lineages diverged long ago. Few differences would indicate a more recent split.

How different is this Y chromosome tree to the previous versions used by the Genographic Project? The number of branches nearly doubled from 667 to more than 1,200 on our new paternal tree. As a result, new connections and new bifurcations (branch splitting) have since emerged. For example, haplogroup C (a male lineage common in South Asians) now shows patterns of deep-rooted relatedness among East Asians, Aboriginal Australians, and Native Americans.

The overall structure of the tree remains consistent with past versions, thus not affecting major haplogroup (or lineage) designations. However, more branches mean greater geographic specificity–helping us narrow down where specific lineages are found and when they originated.

What does this mean for Genographic Project Participants’ results? Male results may have changed slightly since we gained greater insights into the paternal migratory paths and discovered new branch tips on the shared Y tree. In particular, we gained a new understanding of internal branching patterns of the tree and of events that occurred between 10,000 and 60,000 years ago as humans moved to populate every corner of the earth.

What’s next? We are looking at the maternal ancestral tree right now and should have additional information featuring your input in the weeks to come.

This is an exciting moment for The Genographic Project as we can actively show the power of participant involvement in advancing genetics and anthropology. So, thank you again, and please continue to reach out to us with your questions and your stories.

    Last year, my Genographic report showed: 1. Denisovan %, as well as the Neanderthal % Hominin ancestry. Visiting the site today after an absence of almost year, I find the Denisovan category gone. 2. % of Han Chinese. This specificity is also gone today.What explanations did I miss on these changes this past year? I like the original report with apparently more specificity than what is tracked today.

    I gave my husband two Generation 1 DNA kits as gifts, unfortunately, he did not use them before the one year deadline. The kits are unopened. Is it possible to donate these kits back to the Genographic Project to be used to collect the DNA of people you wish to study but who cannot afford a kit? I realize that these kits will not yield the quality of information that a Generation 2 kit can, but perhaps some interesting data can still be parsed from them.

    Hi Miguel:
    7 Years ago my sister did her mtdna with the genome project. The result was MTDNA C, we celebrate our Taino heritage but for our surprise seven years later some Censo documents say my last MTDNA female in the 1830 and her husband where from Valencia Spain. Fact that upside down my tree.Then the journey begun! My personal investigation shows my ancestors are almost every part of the world . In my case, I could tell from my Europeans ancestors brought DNA and MTDNA from everywhere: from Africa, Asia , Middle east , the Siberian, Iceland, to Europe, again to the middle east, Jew , Arab, Canarias Island, Berebere . You name it, and I have it. We have to rethink that the 450,000. Europeans that came to Puerto Rico through the period of the Cedula de Gracia and the ones that came in the first centuries of the colonization brought Africa, Europe, Asia, Middle east in their DNA.( I did also the Autosomal and my dad DNA Y test)
    Maybe is only my ancestors journeys but I have notice similar patron in several puertorican DNA and trees. I’m making this note rethinking the puertorican ancestors journey, it seem more admix that we have thought.

      Hi Aurora,

      Thank you for your comment!
      You are right, there were people from all over the world that came to Puerto Rico. Some researchers have begun to use some new statistical analysis to attempt to learn what groups may have come when. I saw one such study looking at different African lineages, and trying to figure out when and from where they may have arrived. There is so much that we are learning every year with the improving capability to do more and more DNA sequencing. Thanks again!

    I received my results a year ago and have received some updates since then. I much prefer the results I received from Nat Geo than the results some friends have received from other organizations. Some other tests attempt to identify whether someone is “French” or “German” or another nationality instead of focusing more on haplogroups, which are shared across nationalities.

    We had always heard that my grandmother was part Blackfoot, Native American. She sure looked Indian, black hair but had blue eyes, beautiful lady. She was born in Utah in 1893. Her maternal Haplo Group is X2C1 so we can’t tell from this whether she is Native American or Irish/Scottish, as were the parents who raised her. Is there another way to discern her lineage?

    • Miguel Vilar
      June 18, 2015, 12:44 pm

      Cyndy,
      As you noted, you cannot tell based on her mtDNA is she was part Blackfoot since that lineage that you listed in more commonly associated with European groups. The Geno 2.0 test, however, does look at the rest of the genome and can estimate the percentage of Native American markers in her DNA. Testing her, or her closest direct relative with this test you may be able to start to answer that question. Best wishes, MV

    I have cross-checked the Geno results with documentation and historical information I have from traditional family research. The difference I observe with the Geno results is that they are not hesitant to indicate tribes and origins for ALL Earth’s peoples, back to the beginning in southeast Africa. So, in effect, no matter what we all may look like on the outside, we are at heart, all one big family after all!

    Geno 2.0 is a completly useless dna test, total waste of money.

    1. It is incomplete in everywhichway.
    2. You have no way of finding out anything about the people who are in your group. For example, I am Ydna J1-Z1853, they say that 0.3% of all the participants are J1-Z1853, but only 5 of us have shared there story and we know nothing about the rest 2111, as to who they are(ethnic group), where they are from, The Nathional Geographic Genographic Project can at least give us that much information about the participants without jeopardizing their privacy. Only this tiny little information can make this test very valuable.

    Thank you for the comments. I will attempt to answer many:

    -Genographic is more of a deep ancestry (anthropological) test, not a test to find close relatives. Our partners, Family Tree DNA can help with the latter (they use STR mutations).
    – The new tree is on genographic.com, but only the core. To see the complete tree (1000s branches) contact FT-DNA.
    – Reference populations are not updated on Geno 2.0
    – You can join the project through http://www.genographic.com
    – The colors on the map are just for geographic reference
    – Any questions about the science are always welcome, our email address is on our website. Thank you.

    I did Geno 2 about a year ago, and it turned out to be a very efficient way to define my SNPs down to several thousand years ago. People need to understand that this is a deep ancestry test, not something you do to identify family members (cousins.) For that you nee do test Y-STRs, preferably at least the 67-STR panels.

    In some terminal branches, there are those who have defined SNPs into the usual genealogical time frame, and eventually that will be true for far more people when enough have done sequencing of their Y chromosomes, but for now STR testing is the way to test distant family relations.

    I was really excited about this project and was about to sign up when I read all the negative comments above. Very disappointing as I have always believed that Nat Geo was a rigorous scientific organization. It would appear that whoever is in charge of this project is perhaps not up to the challenge. When I read more positive comments I will consider buying into it.

    Very new but interested in this project. However, I notice that the R2, R1a and P2 haplotypes, being displayed in brown on the geographic map of the haplotypes cannot be differentiated. Why is this?

    • Miguel Vilar
      April 13, 2015, 11:26 am

      Hello Rashidah,

      Thank you for your interest. As you can see in many cases we grouped the haplotypes and haplogroups by region. However, R2, R1a and P are very different haplogroups, and with a more detailed map we would certainly separate those geographically.

      Thank you, Miguel

    • Miguel Vilar
      April 23, 2015, 5:52 pm

      The haplotypes can be differentiated, they were only grouped together because of geographical proximity.

    We submitted our DNA in 2010. The story we received back about our ancestry stopped at 10,000 years ago. I found this a little disappointing. For instance due to the ice age NW Europe by that time was hardly populated. Are you already in a position to refine the ancestry story to say a few centuries ago? Or do you wish us to re-submit our DNA?

    • Miguel Vilar
      April 13, 2015, 11:28 am

      Hello Ruurd,

      With mitochondrial DNA and Y-chromosome DNA the story we can tell is often and ancient one. However, since 2012 we have been able to give more specific stories and lineage definitions thanks to the new GenoChip. Read about Geno 2 and the GenoChip on http://www.genogrpahic.com.

    Well, based on the comments above, I’ll be looking elsewhere for a good genealogically based, informative DNA test. The comparison chart I viewed did say that the results of the NG test could be passed into Family Tree, at no charge, but very little detail was forthcoming. Will keep looking for a program that will give value for my dollar.

As you unlock more paths and refine new information a few years from now, will participants be able to go to the NatGeo site and use their ID #s to learn how we fit into the new information?

    I participated a few years ago and received my results pretty quickly. It was interesting to see my ancestral composition but it opened up lots of new questions and insights that I could not explore due to the secrecy behind the science of this project, and the restricted nature of what NatGeo allows you to see.

    There is a list of reference populations that you are matched against, but there is no explanation as to why certain countries are on there and others aren’t. For example, the reference populations in the Balkans are Greece and Bulgaria, but Romania, Serbia, Albania and Macedonia are not listed. When I tried to find out how and why reference populations were created, I was told that it is done through a proprietary formula that is not available to the public.

    I found the heatmaps of my maternal and paternal lineages to be extremely interesting. It was my favorite part of the results, and so I naturally wanted to see the heatmaps for other mtDNA and YDNA haplogroups. Guess what? NatGeo does not think you should be able to see those and there is no way to access them. When I requested the maps for personal study, I was denied.

    Maybe most participants are satisfied with the few bits of info that the project provides, but it is not enough for me, given the $200 price tag at the time I bought into it. It’s not like I’m asking for data that doesn’t exist. I just want to have access to the complete findings of the project, and not just a few tiny bits that NatGeo thinks are relevant to me.

    This latest “Y map” is more of the same. The article says that the project has now mapped the relatedness of over 1200 branches on the Y-chromosome, but all they’ve given us is a crude regional map and a chart with 37 branches, representing a meager 3% of the data treasure trove they have collected. Thanks, I guess…

    I can’t help but to feel cheated.

    My wife’s Y-DNA haplogroup (via testing a paternal cousin) changed from R-P310 to R-V221 (new in Genographic tree?)in December 2014 and now (January 2015) it is back to R-P310. No notification of the changes nor explanations for the flip-flopping has been given. Could you keep us bettter informed so that we can have some confidence in your results? I am sure that we would also like to see what your new tree looks like and how it compares to the ISOOG tree.

    After all, Mongolian have more significant different DNA with Chinese and Southeast Asians rather than Australian Aborigines, Pacific Islander even thought Mongolia and China sibling a neighbor because Mongolian, Ainu Japanese, Australian Aborigines, etc have a Y Chromosome Haplogroup C. In other word, they are an old Asians.

    What a bunch of bunk. How come some men in Western Cameroon (Mbo tribe) have 338,000 years old Y-DNA that has not mutated in all that time, yet we all come from some made up Adam and they don’t? They don’t update mtDNA groups and Y-DNA is all they care about. A shoddy job of it too. How do you explain the men in western Africa?

    So I recently received results identifying haplogroups for me. Will National geographic be sending me refinements relating to geographic specificity or perhaps relating to the reference populations identified for me? Or do I need to pay to be tested again? Thank you for your attention to my query.
