From Discovery News:
Modern humans are known to have left Africa in a wave of migration around 50,000 years ago, but another, smaller group — possibly a different subspecies — left the continent 50,000 years earlier, suggests a new study.
While all humans today are related to the second “out of Africa” group, it’s likely that some populations native to Israel, Jordan, Lebanon, Syria, Australia, New Zealand and Indonesia retain genetic vestiges of the earlier migrants…
And by “earlier migrants” they mean that some of them were messing around with Neanderthals.
This follows a story not so long ago that Neanderthals were possibly red-heads. In my case this would explain a lot.science evolution genetics
