New DNA study shows humankind’s complex origins in Africa

The Khoe and San peoples in southern Africa play an important role for our understanding of the evolutionary history of humans.
These peoples are directly descended from the first branching of the genealogical tree of today’s humans. This is shown in a study led by Uppsala University researchers and being presented in the early online version of the journal Science today.
The study is based on an analysis of 2.3 million genetic variants from seven groups of the click-speaking Khoe and San peoples, a total of 220 individuals from southern Africa. The analysis is the largest genetic study ever of the Khoe and San peoples.
