Researchers find signs of western Eurasian genes in southern African Khoisan tribes

(Phys.org) —A team of researchers with representatives from the U.S., Germany and France has found evidence of western Eurasian genes in Khoisan tribes living in southern Africa. This suggests, the researchers conclude in a paper they've had published in Proceedings of the National Academy of Sciences, that a migration from the Middle East back to Africa occurred approximately 3000 years ago.
