Genetic Evidence Offers Deepest Insights Into Population History

The population of homo sapients that left africa and which eventually branched into the ancestors of all non-Africans was a single group until 50 to 60 thousand years ago. After around 50 thousand years ago, this group separated into several distinct strands that went in very different directions. One of these new splinter groups probably stayed in the near east and left descendants that hung around for a very long time. The oldest modern human genum ever sequenced comes from a gentleman who died and presumably lived in what's now western siberia.
