I have to return some videotapes.

One of science's most puzzling mysteries - the disappearance of the Neanderthals - may have been solved.

Devoured by humans, says a leading fossil expert.

Fernando Rozzi, of Paris’s Centre National de la Récherche Scientifique, said the jawbone had probably been cut into to remove flesh, including the tongue. Crucially, the butchery was similar to that used by humans to cut up deer carcass in the early Stone Age. “Neanderthals met a violent end at our hands and in some cases we ate them,” Rozzi said.
