ElectrixUK discovered 4 months ago- Humans almost became two species
- Kingreaper rated 4 months ago
- Hmmm, possible evidence that humanity was on path to YET ANOTHER speciation event in relatively recent evolutionary history. Could be a cool premise for science fiction to have it actually manage to be speciation... This post (c) Kingreaper: Has a plentiful supply of premises, just doesn't get 'round to using them.

- From the page: "Ancient humans started down the path of evolving into two separate species before merging back into a single population, a genetic study suggests."

- From the page: "Ancient humans started down the path of evolving into two separate species before merging back into a single population, a genetic study suggests. The genetic split in Africa resulted in distinct populations that lived in isolation for as much as 100,000 years, the scientists say. This could have been caused by arid conditions driving a wedge between humans in eastern and southern Africa. Details have been published in the American Journal of Human Genetics. It would be the longest period for which modern human populations have been isolated from one another. But other scientists said it was still too early to reconstruct a meaningful picture of humankind's early history in Africa. They argue that other scenarios could also account for the data. At the time of the split - some 150,000 years ago - our species, Homo sapiens, was still confined to the African continent."

- I just hope this isn't misreported - human beings today *are* one single species, genetically, everywhere on the planet.

- From the page: "The Genographic Project's findings are also consistent with the idea - held for some years now - that modern humans had a close brush with extinction in the evolutionary past. The number of early humans may have shrunk as low as 2,000 before numbers began to expand again in the Late Stone Age." The Earth might have been better off had we succumbed, but I have to say I'm glad to be here!
