DNA from 31,000-year-old milk teeth leads to discovery of new group of ancient Siberians 

Two children’s milk teeth buried deep in a remote archaeological site in north eastern Siberia have revealed a previously unknown group of people lived there during the last Ice Age. The finding was part of a wider study which also discovered 10,000 year-old human remains in another site in Siberia are genetically related to Native Americans — the first time such close genetic links have been discovered outside of the US.
