When asked to name the top place in the world they would like to live, it is a safe bet that few people choose Siberia. That makes it difficult to accept the idea that it was the chosen home of early humans, Neanderthals and Denisovans. Why would they migrate from Africa and other warmer climates to the frigid air and frozen ground of Siberia? Well, the mystery just got a little deeper – researchers analyzing prehistoric DNA from North Asia were surprised to find out it was from a previously unknown group of hunter-gatherers that lived there 10,000 years ago or more. Another strange discovery – the group disappeared 7,500 years ago. And one more … the people may have not only migrated west from Europe but east from North America across the Bering land mass as well. Who were they? A new species? An amalgam of other species? Why would they leave North America to go to Siberia? Can they help solve the mysterious attraction of Siberia?
