Out of Africa, once

Post by Witness »

NYT wrote:A Single Migration From Africa Populated the World, Studies Find

Modern humans evolved in Africa roughly 200,000 years ago. But how did our species go on to populate the rest of the globe?

The question, one of the biggest in studies of human evolution, has intrigued scientists for decades. In a series of extraordinary genetic analyses published on Wednesday, researchers believe they have found an answer.

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.”

OK, more paleontology than archeology, but it's about Our Ancestors®!

Well, the ark landed about there, so it makes sense.

I read about that, very interesting. I'm currently reading Stephen Baxter's Evolution, which is relevant and darn good SciFi. :)
