Massive Genetic Study Supports "Out of Africa" Theory
A massive new study of human genetic diversity reveals surprising insights into our species' evolution and migrations - including support for the theory that the first modern humans originated in Africa - scientists said Thursday.
Researchers compared 650,000 genetic markers in nearly a thousand individuals from 51 populations around the globe - an unprecedented level of detail for a human genetic study. "You get less and less variation the further you go from Africa," said Marcus Feldman, an evolutionary biologist at Stanford University in California and a study co-author.
Such a pattern fits the theory that the first modern humans settled the world in stepping-stone fashion after leaving Africa less than 100,000 years ago.
