Human skull against a black background


Researchers investigating prehistoric DNA have discovered a mysterious group of hunter-gatherers that lived in Siberia perhaps more than 10,000 years ago. 

The find was made during a genetic investigation of human remains in North Asia dating from as far back as 7,500 years ago. The study also revealed that gene flow of human DNA not only traveled from Asia to the Americas — as was previously known — but also in the opposite direction, meaning people were moving back and forth like ping pong balls along the Bering Land Bridge.
