Humans did come out of Africa, says DNA. “Research
revealed in this week’s Nature lends
support to the idea that we appeared in
one location in sub-Saharan Africa and
spread from there, replacing
Neanderthals and other early humans as
we went.

Researchers led by Ulf Gyllensten of the
University of Uppsala in Sweden have found evidence that we are all
descended from a single ancestral group that lived in Africa about
170,000 years ago. And they suggest that modern humans spread across
the globe from Africa in an exodus that took place only around 50,000
years ago.

Gyllensten’s team didn’t scrutinize fossils to come up with these results —
instead the group examined DNA from living people around the world.”
