Europeans Came From Three Ancestry Groupings 85

Taco Cowboy writes A recent study by researchers at Harvard Medical School and the University of Tübingen in Germany has found that present day Europeans are descendants of three different groups of people — A near east farmer group, an indigenous hunter gatherer group, and an ancient North Eurasian group from Siberia. "Nearly all Europeans have ancestry from all three ancestral groups," said Iosif Lazaridis, a research fellow in genetics in Reich's lab and first author of the paper. "Differences between them are due to the relative proportions of ancestry. Northern Europeans have more hunter-gatherer ancestry — up to about 50 percent in Lithuanians — and Southern Europeans have more farmer ancestry." The most surprising part of the project, however, was the discovery of the Basal Eurasians. Before Australian Aborigines, New Guineans, South Indians, Native Americans and other indigenous hunter-gatherers split, they split from Basal Eurasians. The study also found that Mediterranean groups such as the Maltese, as well as Ashkenazi Jews, had more Near East ancestry than anticipated, while far northeastern Europeans such as Finns and the Saami, as well as some northern Russians, had more East Asian ancestry in the mix.

    "Ashkenazi Jews, had more Near East ancestry than anticipated" What!? Off the cuff I'd think they would have 100% Near Eastern ancestry. How much did they anticipate? Apparently a number less than 100.

      I would have expected close to but not quite 100% German and Polish. Considering most Ashkenazi look in every way Polish and German and spoke a German dialect, the original semetic genes are likely thin.

      • Well, the thing is that this study did not compare the genetic makeup of Ashkenazi Jews to that of Germans and Poles. It looked at how much of it came from three ancestral groups which Germans and Poles also descended from. I am going to assume that you would have expected Ashkenazi Jews to have the same proportion of those three groups as Germans and Poles. In order to know if that is a reasonable expectation one would need to know if the Germans and Poles have the same, or close to the same, distribution

      After living in Eastern Europe for so many centuries as a minority, with continuous gene flows, no, I would expect them to have a significant amount of Northwestern Eurasian genes in them. I mean, just look at them (and I don't mean it in a derogatory manner) and compare them with some other ancient-yet-living Middle Eastern populations (Assyrians, Chaldean, Samaritans, Yemenite Jews, Arabs, and pretty much any other Semitic group that has not migrated out of the Levant, Mesopotamia and/or the Arabic Penins

        • You don't need to learn languages to do linguistics. You need to learn about languages. It helps to know the languages involved, but if that was required comparative linguistics would get nowhere. Comparative linguistics works by building on the data gathered about the target languages, often by researchers who went to study them.

            While working on a linguistics minor for my CS degree, I heard a number of versions of the quip that a linguist is someone who knows 100 words in each of 100 different languages. Of course, this should be followed with the observation that the main focus of linguistics is understanding the structures of languages, and vocabulary is interesting only in that it shows relations between languages. This doesn't generally require having a large enough vocabulary to be fluent. Most of the actual linguists I've

Another fact that is almost overlooked by the article is that many proponents of this language family think that it is a usefu

    There's no measurable genetic differences. There's only one race: the human race, and that's all that ever was and ever will be.

      It's not an all-or-nothing situation. There are statistical genetic differences between various groups of people (though superficial features like skin color are often not closely related to ancestral groupings). One of my favorite such statistics was the calculation that some time in the late 1980s, the US population passed the mixing point where more than 50% of Americans now have sub-Saharan African ancestors. Most such people look "white", of course, since they have only a small fraction of African genes.

      I recently read that the accumulated DNA data shows that between 20% and 25% of the US population has "Native American" genes, though again in most of that population is primarily "white". I'm part of that population, with an Ojibwa great-grandmother, though nobody would ever guess by looking at me that I'm not of pure European ancestry.

      One thing I've found difficult to discover is what fraction of the US is purely European. If you try googling the topic, it mostly teaches you one thing: Most people don't understand even such simple statistics. You find lots of matches for the part of the population that's "white" or "of European ancestry", but the phrasing implies that they're talking about people who are predominantly European. There's data on the small populations that are purely African or purely Asian or whatever, but it's hard to find any information on the (probably small) population that's purely European.

      Of course, for most purposes this all qualifies as idle curiosity. But there are at least a few medical reasons for studying it, in addition to general curiosity about where we all came from.

        I don't think you read the article. Since 0% of Europeans are purely European, it seems unlikely the fraction of the US that is purely European would be any larger than that. In general, the only cases where there are persons who are 100% purely a member of any genetic group are identical twins (and triplets, etc.)

  • First of all, what about the highly confirmed hypothesis of the Indo-Europeans' migrations from the Caucasus since the 5th millennium BC, that later split into several groups (italic tribes, greek tribes, celts, slavs, germanic tribes, etc...) ? Most modern-day europeans have been supposed to descend from them. How does this study renconcile with it? Maybe the Indo-Europeans carried the genes of what the study calls "farmers from the Near East"?

      Look at the time frames! The article talks about the genetic influences until 7000 years ago, while the spread of the indo-european tribes started about 5000 years ago. So we are talking about populations in different times eras. And then it's quite sure that the spread of the Indo-Europeans was not so much a complete elimination of the old Europeans but rather an assimilation. The Indo-Europeans came with new social structures and technologies, intermixing with the local population and assimilated them in
    • I think the wording is just off. The 'basal Europeans' are most likely descendants of the Cro Magnon with a sprinkling of Neaderthal. The original stock most likely was from an earlier migration out of Africa.

  • On an evolutionary time scale, this is a snapshot. "Europeans" meant something for several thousand years, but the intermarriage and population growth and travel will commingle DNA in a century or two (evolutionarily known as an "instant"). I'm white and have native American DNA, most black / African Americans are dark skinned and have loads of European DNA, etc etc. These DNA results are interesting but it's like trying to follow a weather pattern, the geographical barriers are toast.
