European Genetics
razib | February 17, 2010The language families of Europe fall into a few broad categories. There are the Indo-European languages, which include the Romance, Germanic, Slavic and Celtic subgroups, along with Greek and Albanian. The Iranian languages and most of the languages of India are also Indo-European. Then there are the languages of Finland and Hungary, which are hypothesized to be of a broader Finno-Ugric family. Whatever the validity of this cluster, the relationship of Hungarian and Finnish to languages which are extant deep into Eurasia, beyond the Urals and into Siberia, are not disputed. Turkic and Semitic…
razib | January 7, 2010In the aughts the elucidation of human pigmentation genetics was of one the major successes of 'omic' techniques. The fact that humans exhibit some continuous variation in complexion was strongly suggestive that more than one gene was at work to generate the range of the phenotype. On the other hand pedigree based studies going back to the 1960s suggested that only a modest number of large effect genetic variants were producing the variance. Today we can say with reasonable certainty that about half a dozen genes account for almost all the between population variation in pigmentation. For…
razib | September 24, 2009A few weeks ago I posted on a paper, Genetic Discontinuity Between Local Hunter-Gatherers and Central Europe's First Farmers.Another one is out in the same vein, Ancient DNA Reveals Lack of Continuity between Neolithic Hunter-Gatherers and Contemporary Scandinavians:
The driving force behind the transition from a foraging to a farming lifestyle in prehistoric Europe (Neolithization) has been debated for more than a century...Of particular interest is whether population replacement or cultural exchange was responsible...Scandinavia holds a unique place in this debate, for it maintained one of…
