This undated photo provided Monday, Aug.12, 2013, by Abri Peyrony Project shows people working at the excavation of the Neanderthal site of Abri Peyrony, southwestern France, where bone tools known as lissoirs, were recently discovered. Researchers have found what they say are the first examples of specialized bone tools made by Neanderthals, a discovery that will add to debates about how advanced Neanderthals were and how much contact they had with modern humans. The discovery is being discussed by scientist, researchers and academics after the findings were published online Monday by the Proceedings of the National Academy of Sciences.
