TED Talk: Human language and caves (video)

Why are these 32 symbols found in caves all over Europe?
TEDWritten language, the hallmark of human civilization, didn't just suddenly appear one day. Thousands of years before the first fully developed writing systems, our ancestors scrawled geometric signs across the walls of caves they sheltered in.

Paleoanthropologist and rock art researcher Genevieve von Petzinger has studied and codified these ancient markings in caves across Europe. The uniformity of her findings suggest that graphic communication, and the ability to preserve and transmit messages beyond a single moment in time, may be much older than we think.

The Roots of Religion: Genevieve Von Petzinger (TEDxVictoria)
(TEDx) Doctoral student in anthropology at the University of Victoria, Genevieve Von Petzinger's main area of interest is understanding the geometric imagery of European Ice Age rock art and how we can use this type of behavior to identify cognitive and symbolic evolution in modern humans. Her work was featured on the cover of New Scientist in 2010 and Science Illustrated in 2011, and she has also appeared on the Discovery Channel's popular program Daily Planet.
