Title: Social Evolution in Hamadryas Baboons and Plio-Pleistocene Hominins: A Baboon Model Revisited
Speaker: Prof. Larissa Swedell
Venue: Room 604a
Baboons of the genus *Papio* have long been used as models for social and ecological evolution in hominins. Here I discuss the utility of a baboon (sub) species that has been heretofore relatively ignored in such discussions, the hamadryas baboon (*Papio hamadryas hamadryas*). I will first discuss patterns of social bonding in hamadryas society, hamadryas male and female reproductive strategies, and the ways in which evolution appears to have shaped these patterns, drawing from two decades of research on a wild population in central lowland Ethiopia. I will then draw parallels between these patterns and those speculated to have characterized early members of the genus *Homo* as well as those found in modern humans.
