Denisova Cave in Siberia’s Altai Mountains is one of the world’s most important
archaeological sites. It is famous for preserving evidence of three early human groups:
Neanderthals, early Homo sapiens, and a third group known as the Denisovans.
Fossil bones, stone tools and ancient DNA gathered from the cave have told a story that is
extremely significant for understanding the early chapters of human evolution in Asia,
going back 300,000 years.
But our new analysis of the cave’s dirt floor reveals that it was also frequented by hyenas,
wolves, and even bears for much of its history.
