Interesting stuff! Scientists have discovered that a group of Eurasians came to eastern Africa some 3,000 years ago, and from there to southern Africa, according to DNA tests of Khoisan individuals.
Humans left Africa some 65,000 years ago, but there was of course Neanderthals and other species living abroad. This new research identifies that a group from southern Eurasia, mainly Sardinia and Italy, came to Africa around 3,000 years ago.
From there, they journeyed down to southern Africa and one thing led to another and the genes of Eurasians mixed with the genes of the Khoisan somewhere between 900 and 1,800 years ago.
A subset of the Khoisan known as the Khoe-Kwadi arrived in southern Africa 2,200 years ago from eastern Africa and are descendants of the travelling Europeans. They are pastoralists by nature, unlike the hunter-gathering techniques of the San.
This new research came as a shock to the scientists at Harvard University, and they believe that the Neanderthal gene might be more widespread than originally thought.
