Africans Have The Most Diverse DNA
A May 2002 study by researchers at the University of Chicago’s Department of Ecology and Evolution, examined three groups of people, Africans, Europeans, and Asians. The researchers found greater genetic diversity among Africans than among Eurasians, and that genetic diversity among Eurasians is largely a subset of that of Africans. Because there is no other similar center of genetic diversity outside of Africa, the DNA evidence supports the “Out of Africa” model.
Another study in July 200 by the University of Cambridge, England, found that the lowest genetic variation was found in ancient populations from South America and Australia, the two main inhabited regions most remote from Africa.
Andrea Manica, the team’s lead, concluded, “The more you move away from that center of diversity where you started, the less diversity you have.”
The study places the original roots of modern humans in south-central Africa. In the middle of this region lies the Great Rift Valley—often referred to as the “cradle of humanity.”
