One of the enduring questions of human origins is when, where and how we "Behaviorally Modern Humans" emerged and why and how we eventually replaced all the other human-like species. This series takes a fresh look at the situation today with a critical examination of the available evidence from multiple sources. Ofer Bar-Yosef (Harvard Univ) leads off with a talk about Evidence for the Spread of Modern Humans, followed by Christopher Ehret (UCLA) on Relationships of Ancient African Languages, and Iain Davidson (Univ of New England, Australia) on Stone Tools and Cognition: Lessons from Australia.
