- Human beings may have had a brush with extinction 70,000 years ago, an extensive genetic study suggests. art.spencer.wells.ng.jpg Geneticist Spencer Wells, here meeting an African village elder, says the study tells "truly an epic drama." The human population at that time was reduced to small isolated groups in Africa, apparently because of drought, according to an analysis released Thursday. The report notes that a separate study by researchers at Stanford University estimated that the number of early humans may have shrunk as low as 2,000 before numbers began to expand again in the early Stone Age.

- "Human beings may have had a brush with extinction 70,000 years ago, an extensive genetic study suggests. The human population at that time was reduced to small isolated groups in Africa, apparently because of drought, according to an analysis released Thursday. The report notes that a separate study by researchers at Stanford University estimated that the number of early humans may have shrunk as low as 2,000 before numbers began to expand again in the early Stone Age. "This study illustrates the extraordinary power of genetics to reveal insights into some of the key events in our species' history," said Spencer Wells, National Geographic Society explorer in residence. "Tiny bands of early humans, forced apart by harsh environmental conditions, coming back from the brink to reunite and populate the world. Truly an epic drama, written in our DNA." Wells is director of the Genographic Project, launched in 2005 to study anthropology using genetics. The report was published in the American Journal of Human Genetics. Studies using mitochondrial DNA, which is passed down through mothers, have traced modern humans to a single "mitochondrial Eve," who lived in Africa about 200,000 years ago."

- This is an old, old story. Why is being reported as something new and embellished with conjectures that have nothing to do with genetics?
- MamaJS rated 3 months ago
- Mitochondrial DNA (passed down through mothers) shows all humans alive today came from one proverbial "Eve" alive more than 200,000 yrs ago. Further research suggests that 70,000 years ago massive drought threatened the human race, breaking up the population into small groups that eventually formed separate societies. We got this all from strands of DNA. Crazy, huh?

- hhhmmmm! if it had gone all the way that would have saved me lots of trouble today. guess this means i'm related to everyone though
