A new study casts doubt on the idea that our ancient ancestors would have interbred with Neanderthals.
Research in to the Neanderthal genome revealed genes that live on in modern humans, a sure sign that the two species would have interbred at some stage in the past - or so it seemed. Now new research has suggested that the reason we share genes with Neanderthals is because both species descended from a common ancestor and not because of cross-species interbreeding.
"You cannot prove there was never any hybridisation," said Andrea Manica of the University of Cambridge. "But none of the evidence [for hybridisation] is convincing."
"Andrea Manica and Anders Eriksson at the University of Cambridge have now built a model to demonstrate a non-interbreeding explanation for the 2010 result."
