Scientists believe they've discovered a third group that interacted with humans and Neanderthals.

They already have evidence to show that humans and Neanderthals interbred, and now it seems there may have been an additional contribution to our DNA.

"There are tantalising hints that the find strengthens the case for a third major group of hominins circulating in Eurasia at the same time as early humans and the Neanderthals. It might possibly even prove all three groups were interbreeding."
