Photo: Massive Genetic Study Supports "Out of Africa" Theory



A map shows human migration routes beginning about 100,000 years ago, based on mitochondrial (yellow) and Y-chromosome (blue) DNA evidence collected by the National Geographic Society's Genographic Project and other sources.

A separate, massive new gene study confirms much of this information, including the "out of Africa" theory that modern humans first appeared in Africa and then spread to the rest of the world via the Middle East.
