Scientific evidence suggests that the origin population of all modern humans resided in the southern African sub-region, perhaps in a coastal context. The oldest evidence for coastal resource use comes from Pinnacle Point on the south coast of South Africa, where a scientific team has been conducting research on these original coastal people for nearly twenty years. Curtis W. Marean will discuss ancient humans’ reliance on seafood and how human evolution may have been impacted by struggles over this resource. Marean is a professor at Arizona State University’s Institute of Human Origins and School of Human Evolution and Social Change. He is also the principal investigator for the South African Coast Paleoclimate, Paleoenvironment, Paleoecology, Paleoanthropology (SACP4) project based near Mossel Bay at Pinnacle Point.
