DNA data back theory of humans evolving in Africa

WASHINGTON (Reuter) Scientists said Monday they have gathered more genetic evidence to support the theory that the human race originated in Africa.
The team studied nuclear DNA from 63 Asians, 72 Africans and 120 Europeans and found the greatest diversity in the Africans, 20 percent more than the other groups. The scientists assert this is a strong indication of Africans being the world's "oldest" population.
"Greater genetic diversity in human populations from Africa has been a cornerstone of the argument for an African origin of modern humans, since this greater diversity suggests a greater 'age' for African populations," they wrote.
