We Can Now Recover DNA from Possessions

 ...and it may help us work out more about the Denisovans.

Researchers were able to find human DNA on a pierced deer tooth found in Denisova Cave. The deer tooth had apparently been turned into a necklace.

We now know that the necklace was owned by a single person and was owned, made by, or both by a woman. She was a modern human connected to the Ancient North Eurasians.

The tooth was 20,000 years old.

If we can push it back further we can expand our knowledge of populations that did not bury their dead.
