Neandertals Had Sophisicated Bone Based Technology After All

Two research teams from the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany, and the University of Leiden in the Netherlands have jointly reported the discovery of Neandertal bone tools coming from their excavations at two neighboring Paleolithic sites in southwest France. The tools are unlike any others previously found in Neandertal sites, but they are similar to a tool type well known from later modern human sites and still in use today by high-end leather workers. This tool, called a lissoir or smoother, is shaped from deer ribs and has a polished tip that, when pushed against a hide, creates softer, burnished and more water resistant leather. The bone tool is still used today by leather workers some 50 thousand years after the Neandertals and the first anatomically modern humans in Europe.

Modern humans replaced Neandertals in Europe about 40 thousand years ago, but the Neandertals' capabilities are still greatly debated. Some argue that before they were replaced, Neandertals had cultural capabilities similar to modern humans, while others argue that these similarities only appear once modern humans came into contact with Neandertals.

"For now the bone tools from these two sites are one of the better pieces of evidence we have for Neandertals developing on their own a technology previously associated only with modern humans", explains Shannon McPherron of the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany. He and Michel Lenoir of the University of Bordeaux have been excavating the site of Abri Peyrony where three of the bones were found.

"If Neandertals developed this type of bone tool on their own, it is possible that modern humans then acquired this technology from Neandertals. Modern humans seem to have entered Europe with pointed bone tools only, and soon after started to make lissoirs. This is the first possible evidence for transmission from Neandertals to our direct ancestors," says Marie Soressi of Leiden University in The Netherlands. With William Rendu of the CNRS, Soressi and her team found the first of four bone tools during their excavation at the classic Neandertal site of Pech-de-l'Azé I.

However, we cannot eliminate the possibility that these tools instead indicate that modern humans entered Europe and started impacting Neandertal behavior earlier than we can currently demonstrate. Resolving this problem will require sites in central Europe with better bone preservation.
