The Earliest Group Of Modern Humans To Branch Off Survived Until Just 2,300 Years Ago

Oxford Journals, Genome Biology and Evolution

Burial site and skeletal remains of the St. Helena marine forager, who was at least 50 years old when he died



DNA from a 2,300-year-old skeleton suggests that the earliest known group of modern humans to branch off from the wider genetic population survived until astonishingly recently. The finding supports the case that southern, rather than eastern, Africa is humanity's ancestral home.

Mitochondrial DNA, passed on only from the mother, demonstrates that all humanity is descended from a single ancestor around 200,000 years ago. Archaeological evidence points to the Omo Valley, where fossil evidence suggests that Homo sapiens roamed Africa 195,000 years ago.

Gracious Queen I hope you do come back to destee...I see last time you were online here was 6 years ago on my birthday...I was probably probably taking a puff on that good 'ol stuff at the time...maybe sitting back sipping Coffee, Tea, or Wine...I just had to go back and read your previous posts.
