A few months ago I read Empires of the Silk Road, where the author makes the argument that contrary to the common perception of Inner Asians as uncouth barbarians who were inimical to civilization as we understand it, in fact these populations were critical to the emergence of particular civilized values, as well as their…

Interesting that I just pointed to Neandertal DNA, a really big story just came out on ancient Greenlander genetics, Whole Genome of Ancient Human Is Decoded: The genome of a man who lived on the western coast of Greenland some 4,000 years ago has been decoded, thanks to the surprisingly good preservation of DNA in…

After reading Genetic Discontinuity Between Local Hunter-Gatherers and Central Europe’s First Farmers I’m left scratching my head a bit. Cut-out black & white models really benefit from lack of data, and now that there’s some serious data I think perhaps that we need to think about starting from a clean slate in many ways. The…

Pots, people & seeds

There’s a new paper in PLoS ONE, Craniometric Data Supports Demic Diffusion Model for the Spread of Agriculture into Europe. That’s fine. There are two extreme models about how farming might have spread in Europe. One model suggests that farmers replaced non-farmers genetically. Another model posits that there was no discernible movement of population, but…

Dienekes points me to a new paper, Demographic history of Canary Islands male gene-pool: replacement of native lineages by European (PDF). Here are the results: Autochthonous (E-M81) and prominent (E-M78 and J-M267) Berber Y-chromosome lineages were detected in the indigenous remains, confirming a North West African origin for their ancestors which confirms previous mitochondrial DNA…

The secret history of Africa

In light of the relatively recent interaction of Bantu farmers and Pygmies in Central Africa, this paper is of note, Genetic and demographic implications of the Bantu expansion: insights from human paternal lineages: The expansion of Bantu languages, which started around 5,000 years before present (YBP) in west/central Africa and spread all throughout sub-Saharan Africa,…

Another response by Etienne Patin, lead author of Inferring the Demographic History of African Farmers and Pygmy Hunter-Gatherers Using a Multilocus Resequencing Data Set, to a follow up post:

Neandertal phylogeography

Genetic Evidence of Geographical Groups among Neanderthals: The Neanderthals are a well-distinguished Middle Pleistocene population which inhabited a vast geographical area extending from Europe to western Asia and the Middle East. Since the 1950s paleoanthropological studies have suggested variability in this group. Different sub-groups have been identified in western Europe, in southern Europe and in…
