The rich racial diversity of modern humanity owes its existence to geographic separation and the reproductive isolation this separation has created. Humanity began in Africa. (To be more specific, the evidence points to the grasslands or savannahs of East Africa over two million years ago as the birthplace of the genus Homo.) If it had stayed there, limiting its existence only to Africa (as did the Gorillas and Chimpanzees, as well as many other genera), the degree of human racial diversity would have been much less than what it became, and the great majority of the diverse races of humanity that have existed during the last two million years, as well as the great majority of modern races, would have never existed. There would have been far fewer branches on the human family tree. But humanity did not limit its existence to sub-Saharan Africa. The ancestors of the non-African races migrated out of Africa and spread to almost every inhabitable area of the earth. racialcompact/racialdiversity.html
