Domestication & Human Evolution (CARTA)
The domestication of other species has played an undeniably central role in the evolution of modern humans, and in our planetary dominance and success. Researchers have over the years investigated the genetic underpinnings and the anatomical, neural, physiological and behavioral consequences of domestication across a number of animal species – but largely independently of each other. Recently, a convergence of views has led to the notion that the study of animal domestication may tell us something not only about our relationship with domesticated species since perhaps at least the Pleistocene, but also about our own evolution as a species in the more distant past. This symposium brings together researchers from a variety of research backgrounds to examine these concepts and to elucidate further the possible role of domestication in human evolution.

Richard Wrangham: Did Homo sapiens Self-Domesticate? 21:15
(Visit: http://www.uctv.tv) In this talk Richard Wrangham (Harvard Univ) puts forth the theory that Homo sapiens are, in fact, a self-domesticated species. He defines “self-domestication” as the evolution of a reduced propensity for reactive aggression (compared to an immediate ancestor), without the active involvement of another species. He then shows that communal sanctions practiced by hunter-gatherers, which depend on proactive aggression, provide a leading candidate mechanism selecting against high levels of reactive aggression. He therefore proposes that human self-domestication is an ironic consequence of a particularly well-developed facility for proactive aggression, and concludes that humans did indeed self-domesticate, providing a critical underpinning for inter-individual tolerance and cooperation.
