Epic trek for Stone Age farmer
From: AFP April 28,
.... DNA analysis of four Stone Age humans in Sweden reveals how agriculture spread from the Middle East about 11,000 years ago to Europe about 6000 years later. DNA from four 5000-year-old skeletons showed one had been a farmer from a people linked to present-day Cypriots, co-existing 400km away from the community of the other three, who had been hunter-gatherers with northern genes. Researchers said the two groups "had entirely different genetic backgrounds and lived side by side for more than a thousand years, to finally interbreed".
