First migration from Africa less than 95,000 years ago: Ancient hunter-gatherer DNA challenges theory of early out-of-Africa migrations

Recent measurements of the rate at which children show DNA changes not seen in their parents -- the "mutation rate" -- have challenged views about major dates in human evolution. In particular these measurements have made geneticists think again about key dates in human evolution, like when modern non-Africans split from modern Africans. The recent measurements push back the best estimates of these dates by up to a factor of two. Now, however scientists present results that point again to the more recent dates.
