Talking Primates with Frans de Waal

Frans de Waal is a primatologist who's challenged male supremacy in evolution, the belief that monkeys don't perceive images as we do, and the idea that they don't possess emotions ascribed to humans. His new book, Our Inner Ape, posits that the human duality of good and evil is in fact something we've inherited directly from primates. [from MetaFilter.com]
