Neanderthals and humans interbred ‘100,000 years ago’

Neanderthals and modern humans were interbreeding much earlier than was previously thought, scientists say.

Traces of human DNA found in a Neanderthal genome suggest that we started mixing with our now-extinct relatives 100,000 years ago.

Previously it had been thought that the two species first encountered each other when modern humans left Africa, about 60,000 years ago.
