Paleoanthropologist Tim Weaver at the University of California at Davis also noted that our species apparently could live at higher population densities than Neanderthals. As a result, this slight difference, with or without interbreeding, would have led to us replacing them.

"A lot of scenarios have been imagined, from peaceful 'flower child' behavior to violent interactions to even cannibalism," Harvati said. "I think a lot of these scenarios happened. I think we probably tried interbreeding and maybe it worked, maybe it didn't. I'm sure there was violence at times. I think in some places they went extinct before modern humans even arrived. But you don't even need any of those if there is even a slight advantage in how many offspring modern humans produce successfully as opposed to Neanderthals."

However, if Neanderthals did coincide with modern humans until 24,000 years ago, then we might not have had anything to do with their disappearance. Instead, evolutionary biologist Clive Finlayson at the Gibraltar Museum in Spain speculates the Neanderthals fell victim to a cooling of the climate that deteriorated their environment too rapidly for them to adapt.
