Biologists Create Genetic Map of Europe

Death Metal Maniac brings us a story from the New York Times about a team of scientists who were able to relate genetic differences to geographical origins. Countries such as Germany, Austria, and France occupy the central area of the genetic map, with Italy, Finland, and the UK being relative outliers. Quoting: "All the populations are quite similar, but the differences are sufficient that it should be possible to devise a forensic test to tell which country in Europe an individual probably comes from, said Manfred Kayser, a geneticist at the Erasmus University Medical Center in the Netherlands. ... Genomic sites that carry the strongest signal of variation among populations may be those influenced by evolutionary change, Dr. Kayser said. Of the 100 strongest sites, 17 are found in the region of the genome that confers lactose tolerance, an adaptation that arose among a cattle herding culture in northern Europe some 5,000 years ago." Update: 08/16 15:11 GMT: Reader iminplaya points out the source article, which contains the technical details behind the study.

    I recommend two books here:

    The Clash of Civilizations and the Remaking of World Order, by Samuel Huntington
    The Great Human Diasporas: The History of Diversity and Evolution, by Luigi Cavalli-Sforza et al

    Once humans evolved from apes, they went through several stages to create modern humans.

    After that, modern humans underwent more aggressive development. This differentiated population groups.

    Much like different programming languages are optimized for different tasks, but you can create just about anything in just about any language, human populations are different based on the optimizations that came about through their branch divergence.

    This creates ethnicities, nationalities, and clines as mapped by Cavalli-Sforza.

    Huntington points out that most of our modern wars have been caused by the nation-state, or an "imperial" grouping by politics that crosses these optimization lines, and suggests that as the superpower age winds down, people will identify with their optimization more than abstract and often illusory political concepts.

    This is especially useful in understanding the difference between Georgia, Ossetia and Russia. For those who live in nation-states of an imperial nature, like the United States, Canada, Russia or UK, it's hard to grasp this, but not every country views itself as composed of generic people.

    They view themselves as an organic nation, a notion which we may quaintly call "tribalism" yet seems to unite people with values more solidly than financial or political motivations.

    The future will be determined by the struggle for these organic nations to define themselves.

    All IMHO.

    Finland is an interesting convergence of east and west. Their language is most closely related to Japanese and Hungarian; their population seems to be halfway between Swedes, Baltics and an Asian precursor.

    Max Muller classified the Turanian language family into different sub-branches. The Northern or Ural-Altaic division branch compromised Tungusic, Mongolic, Turkic, Samoyedic, and Finnic. The Southern branch consisted of Dravidian languages like Tamil, Kannada, Telugu, Malayalam, and other Dravidian languages. The languages of the Caucasus were classified as the scattered languages of the Turanian family. Muller also began to muse whether Chinese belonged to the Northern branch or Southern branch.[31]

      Finnish is not related to Japanese. Finnish is a member of the Finno-Ugrian/Uralic language family, which does include Hungarian, Estonian and a number of minority languages spoken in Russia on either side of the Urals. Japanese is a language isolate, which some linguists have attempted to group under the Altaic umbrella (e.g. Turkic, Tungusic and Mongolian languages) but with little acceptance. No mainstream Uralicist believes in a genetic relationship between the Uralic and Altaic languages, though of course the Turkic languages influenced several Uralic languages somewhat in terms of lexicon and morphosyntax after Turkic expansion.

      The language record does not mirror the genetic record, necessarily, but it provides a useful clue.

      Linguists get rather sick of hearing language grouping identified with genes. The speakers of the Uralic languages are widely disparate in terms of "race", with the very Asian Samoyed peoples contrasting with the quite European Hungarians, and the Udmurts have both within the same nation.

    Surprising how far "out there" the Finnish genetic makeup is, considering the long period of integration with Sweden. It's also interesting that this kind of research may give us the final pieces to jigsaw of migration that took place from the Urals to Central and Northern Europe. This great migration of the tribes is what lead to Finno-Ugrian people ending up around the Baltic and in Hungary, but it's still unclear where the tribes "split up", one lot heading north and the other west. The closeness of the Hungarian genetic makeup to other Central Europeans must reflect the massive amount of migration and conquest that occurred across that region (by various Slavic and Turkic peoples in particular), along with a fair bit of Germanic immigration through trading.

    1. Re:Interesting by CRCulver · · Score: 4, Interesting

      The history of Hungarian migration is pretty clear, actually. The Hungarians were living with their closest Uralic brethren, the Khanty and Mansi tribes, in the south Russian steppes around the beginning of the Common Era. The expansion of the Turkic peoples brought a tribe, evidentally speaking a Chuvash-type language, into contact with some Hungarians, who then learnt horsemanship and began to move west. A number of Hungarians remained behind, and when the Friar Julianus visited the area eight hundred years ago, he was able to communicate with them.

      The Hungarian migration to the Carpathian Basin happened fairly recently compared to the spread of Uralic languages to northwestern Russia, Finland and Scandinavia, which must have been complete a thousand years before the beginning of the Common Era.

    1. Re:My wife is Finnish by vuo · · Score: 3, Informative

      Actually you can't ignore the structure of the language. Finnish basically doesn't have monosyllablic words except for common particles; two syllables is the minimum. This feature appears to be very old and integral to the language. So "two" has two syllables "kak-si" and "ten" is "kym-men-" (oblique form, "ten" alone is "kymmenen"). So when English goes twen-ty-two, Finnish has kak-si-kym-men-tä ("two of tens").

      The second difference clearly exploited is the case agreement. In fact, "twenty two" is two words "kahdessa kymmenessä". Now because the last has the suffix -ssä, the rest of the entire expression also has the same -ssa, which is repeated for each word. So we get "kuudessa kymmenessä tuhannessa kahdessa sadassa viidessä" ("in 60205") for "kuusi kymmentä tuhatta kaksi sataa viisi" ("60205"). As you can see, this redundancy increases syllable count by 40-50%, without being really "complex" in the same sense of spelling bee words.

      Another problem is that although it is not recommended to write together all possible compounds, for some reason all numerals are still faithfully written in long strings like that. You could write, in principle, all genitives together, like in German (think "Donaudampfschiff...").

  9. Altaic to Japanese by burnitdown · · Score: 3, Informative

    I think this one will be under debate for some time. Japanese inherits from multiple sources; whether it once had an Altaic root or contributing source is still under debate among some linguists, as far as I know.

    A better explanation:

    There is no such thing as a Finno-Ugro-Ural-Altaic language group.

    There are Uralic and Altaic language families, and the Uralic family
    divides up into two stocks, Finno-Ugric and Samoyed. The limits of Altaic
    remain controversial, with Turkic, Mongolian, and Tungusic constituting
    the core group, and Korean, and possibly Japanese being outliers.

    The Uralic, and particularly the Finno-Ugric languages within them, are
    closely related enough that the relationship can be demonstrated by
    application of the traditional methods of comparative linguisics based on
    systematic sound correspondences in basic inherited vocabulary. Within
    Altaic the number of putative cognates is far smaller, and the distinction
    between inherited words and *WanderwÃrter* is not always clear. The
    relationship between them is based more on typological similarities than
    on the presence of inherited morphemes exhibiting systematic phonological
    correspondences. Japanese, and particularly Korean, although undoubtedly
    demonstrating some Altaic-like structural features, are both strongly
    mixed languages with elements of Sinetic (Chinese) and, particularly in
    the case of Japanese, Malayo-Polynesian in their core structures.

    I recommend the same books as burnitdown, only you should read them and not just name-check them. I read Huntington's Clash of Civilizations when it was first published in Foreign Affairs. It says nothing at all about genetics or "optimization", only super-national cultural groups called 'civilizations', which are genetically diverse (see list here ). You can read more here.

    I haven't read Cavalli-Sforza, but The Economist seems to think that his work challenges the assumption that there are significant genetic differences between human races, and indeed, the idea that 'race' has any useful biological meaning at all. Hmmm ... that seems opposite the ideas that burnitdown cited.

    So Burnitdown is just talking out of his backside, start to finish. There is no outside support for it at all. I can't even imagine how it applies to Georgia, Russia, and North & South Ossetia. Does anyone know closely their populations correlate genetically? And why, on that basis, would South Ossetians want Russian more than Georgian citizenship? What the heck is 'Russian' genetically, anyway -- the country stretches from Europe to the Pacific; are they really genetically homogeneous?

      Your argument is basically: genetics play no part since my upbringing(environment) plays a part. Don't you believe that genetics can also play a part? You are probably one of those persons who believe that any other argument is heresy and that genetic differences should not be researched.

      With this I differ - of course the social environment plays a part - but there are genetic differences between population groups. Research into this should be encouraged and not suppressed (people doing research today are in the same position as Galileo - just look at how E.O. Wilson was treated).

      Where does this genetic optimization come in?

      Some researchers suggested that evolutionary pressures such as the environment (e.g. long cold winters, etc...) could cause differences in human genetics. The optimization would therefore be on the best evolutionary strategy for this environment. Whether this happened or not is debatable - but you have to admit that it is a plausible scenario.

If we look at Finland's geographical location and it's history it would be a surprise if we would be genetically closer to our European neighbors. Geographically we have been isolated by other nations and people, yes other people have traded and had impact with Fins but that interaction have been very small compared as people have had to travel with boat to hear. Notable feature of Finland's geographical location in periferia of Europe was that Mongols didn't invade it. Also after Fins were converted to Catholicism the eastern regions of Finland were more or less in constant war/conflict with their eastern relatives that were converted to Orthodox faith. In addition we should also note the kingdom of Sweden had severe restrictions on who could come and locate to Finland. In example after the Lutheran reformation it was forbidden and punished by death for other than reformed to come or locate to the kingdom. Another example is that Jews were completely forbidden on locating to Finland, only after Finland became a part of Russia were Jews allowed to locate to Finland. In this sense its not a surprise that we are in the edge of the map separated from others.

    I also don't think that Finnish position in the edge of the map wouldn't change even if there had been samples from Estonia, Lithuania, Latvia, Ukraine and Russia. The Baltic nations have been in constant touch with Germans, Polish and Russians, but not as much with Finnish or Swedish. It would be interesting to know how close related Fins are to Ukrainian and Russians, but I believe that both of them might be closer to central Europeans as Germanic tribes have originally come from east and more importantly all these nations have interacted quite much with each other, note in example Volga Germans, and of course have endured same invasions as in example Mongols.

    It would be nice to have more data and more results from different areas, but then again in a big picture data about such a small populations like Sami people wouldn't really make difference. On a note about Sami people, I read from Helsingin Sanomat that Finland is divided to too genetically different populations, the genetic line goes from Oulu to Kotka. People living in western Finland are genetically more related to Swedish and people living in the eastern and northern section resemble more on original natives that came to Finland. This of course nicely proves that there is something different about those evil bastards from Savo ;)
