The issue of where humans emerged was once answered in religious terms--i.e. of Jewish folklore. The answer was the Garden of Eden--first populated by Adam and Eve.

But note that many religions state that humans spring from religious origins--i.e. directly created by some god.
Darwin(1871) proposed Africa as the place of human origins, because the closest animals to humans were the primates--of chimpanzees and apes, which lived in Africa.How old is it?
