I find this stuff interesting:
In the journal Nature, three separate teams of geneticists survey DNA collected from cultures around the globe, many for the first time, and conclude that all non-Africans today trace their ancestry to a single population emerging from Africa between 50,000 and 80,000 years ago.
“I think all three studies are basically saying the same thing,” said Joshua M. Akey of the University of Washington, who wrote a commentary accompanying the new work. “We know there were multiple dispersals out of Africa, but we can trace our ancestry back to a single one.”
Pretty interesting that basically one group of people leaving Africa populated basically the entirity of the rest of the world. I guess in the past we assumed it was multiple waves of people. I guess the working theory was they left due to drought in Africa to seek food. Some went North (what would become Europe), some went East (what would become Asia).
Raise a beer to your ancestors if you drink I guess, lol. They must've been tough mofos to make the journey and survive.
