    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.
