Uh oh: Humans implicated in extinction of Neanderthals?

Now scientists analyzing two 41,000-year-old teeth from two Protoaurignacian sites in Italy find that the fossils belonged to modern humans.

“We finally have proof for the argument that says that modern humans were there when the Neanderthals went extinct in Europe,” study lead author Stefano Benazzi, a paleoanthropologist at the University of Bologna in Ravenna, Italy, told Live Science. …

They also compared DNA from an upper incisor tooth found in another site in Italy — Grotta di Fumane — with that of 52 present-day modern humans, 10 ancient modern humans, a chimpanzee, 10 Neanderthals, two members of a recently discovered human lineage known as the Denisovans, and one member of an unknown kind of human lineage from Spain, and found that the Protoaurignacian DNA was modern human.

Since the Protoaurignacians first appeared in Europe about 42,000 years ago and the Neanderthals disappeared from Europe between about 41,000 and 39,000 years ago, these new findings suggest that Protoaurignacians “caused, directly or indirectly, the demise of Neanderthals,” Benazzi said.

It remains unclear just how modern humans might have driven Neanderthals into extinction, Benazzi cautioned.
