Recent admixture in West Eurasia (including Europe)
A new open access paper at Current Biology looks at the role of recent admixture in the formation of the present-day West Eurasian gene pool. It appears to be an updated version of a paper from last year which I found somewhat disappointing (see here). This effort is a lot better; it's more detailed and sophisticated, and the authors are more cautious with their interpretations of the data.
That's it for now, but I'll have a lot more to say about these results soon at my other blog when more ancient DNA data rolls in from southern Europe and the Near East.
Below is Figure 4A from the paper, which shows the proportions of admixture from outside of Europe and West Asia among a wide variety of West Eurasian groups.
