Just the other day we read a report on FR about a team of scientists who discovered that race had no meaning genetically -- now we find out that there really IS such a thing as race?!?!
But seriously, I have a copy of "The History and Geography of Human Genes" by Cavalli-Sforza et al, that I got in 1994, that says pretty definitively what this article says. The book is as big as an unabridged dictionary, with chart after chart and map after map of very rigorous, thoroughly annotated analysis of DNA from thousands of blood samples from all over the world.
Point being, why is this being released as if it were a new insight?
