Days of high adventure
I've redesigned and streamlined my Principal Component Analysis (PCA) plot of West Eurasia in anticipation of the arrival of many more ancient samples. Rumor has it we'll not only get stuff from the Balkans, but also finally from the steppes north of the Black Sea. Moreover, apparently 12 of the 15 skeletons recently unearthed at the Harappan-era Rakhigarhi site have been genotyped, and we should see a paper, as well as hopefully the genotype data, by the middle of next year. I'd say my new plot does a better job of highlighting relationships between the different prehistoric groups and population shifts across space and time. The datasheet is available here.
