Wave-of-advance models of the diffusion of the Y chromosome haplogroup R1b1b2 in Europe.

Whether or not the spread of agriculture in Europe was accompanied by movements of people is a long-standing question in archeology and anthropology, which has been frequently addressed with the help of population genetic data. Estimates on dates of expansion and geographic origins obtained from gen...
