|Neandertal jewelry shows their symbolic smarts|In: Science (Washington). American Association for the Advancement of Science: Washington DC. ISSN 0036-8075, more
A handful of marine mollusk shells, possibly used as necklaces and paint cups, shows that Neandertals expressed themselves symbolically, say the authors of a paper published online this week in the Proceedings of the National Academy of Sciences. They argue that the findings suggest that social and demographic factors, rather than cognitive differences, best explain why so-called modern behavior was relatively rare among Neandertals.
