Evidence of Cannibalism: Did Neanderthals Eat Each Other?

Neanderthal bones uncovered in a Belgium cave show unmistakable signs of butchery, and scientists said they are the first evidence of Neanderthal cannibalism in northern Europe. "The big differences in the behavior of these people on the one hand, and the close genetic relationship between late European Neanderthals on the other, raise many questions about the social lives and exchange between various groups," Hervé Bocherens, one of the lead researchers, told CBS News.
