Humans Helped Kill Off Neanderthals?

That's right. (Modern) Humans might've helped kill off Neanderthals.

Violent past

Scientists are continuing to refine their understanding of early Homo sapiens and Neanderthals, with hopes of also resolving the mystery of how the latter species went extinct while we did not. Past research has yielded conflicting evidence on interbreeding between the two species, but the new study clearly shows the opposite of affection.

In fact, another Neanderthal skeleton dating back some 36,000 years and found in France showed signs of a scalp injury likely caused by a sharp object that may have been delivered by a modern human at the time, Churchill said.

"So if the Shanidar 3 case is also a case of inter-specific violence and if Shandiar 3 overlaps in time with modern humans, we're beginning to get a little bit of a pattern here," Churchill said.

Competition for resources with modern humans, along with other factors, may have also played a role in the die-off of Neanderthals, the researchers say.
