Jan. 14, 2009 -- A trio of new studies on prehistoric weapons suggests Neanderthals made sophisticated weapons and tools -- possibly including the first sticky adhesive -- but they lacked the projectile weapons possessed by early humans. The missing technology, along with climate change and competition with arrow-shooting humans, may have contributed to the Neanderthals' eventual extinction. "While we are not suggesting that modern humans were directing projectile weapons against Neanderthals, it is certainly possible that at times they did so," Steven Churchill, co-author of one of the papers, told Discovery News. Churchill, an associate professor of evolutionary anthropology at Duke University, and colleague Jill Rhodes compared Neanderthal fossils with those of prehistoric and modern humans, focusing on the shoulder and elbow.

She explained to Discovery News that modern athletes, like baseball pitchers and handball players, often show a characteristic backward displacement at the shoulder joint. Usually just one joint shows this, since most people have a preferred throwing arm. The anthropologists found this telltale skeletal characteristic in the early modern European fossils, but not in the Neanderthals. The findings are published in the current issue of the Journal of Human Evolution.
