F3-statistics
measures common genetic drift between populations. I have done a simple run using ancient genomes and Eigensoft’s qp3Pop program, comparing all those ancient genomes to present-day populations
and moved results to Excel graphics. The
bigger the result is the more the present population shares drift with ancient
samples.

I couldn’t
resist to look why I have at 23andme many “cousins” in Southern Russia and
Ukraine, but no one in Nothern Russia.
This looked weird because I have heard always that the Finns are from
the north. Indeed, Western Finns, like
me, are closer Ukrainians in terms
of the common genetic drift than Northern Russians (Mordva and Russian people closer
White Sea). Surprising.
