Rare genetic sequences illuminate early humans’ history in Africa
-

These preliminary results suggest that more than 40,000 years ago, two of the groups — the San and the Baka Pygmy — were roughly twice the size of other ethnic groups present at the time, and that the San and Baka overlapped in central-eastern or southern Africa.
The findings also suggest that there was intermingling during that period between the Hadza, the San in southern Africa and the Baka in central Africa, all of whom were traditionally hunter-gatherers.
