Waves of Change

Around 170,000 years ago people living in sea caves on South Africa’s south coast were repeatedly collecting and eating shellfish from the nearby coastline. It marked an important behavioral shift from the occasional collection of aquatic resources to systematic relying on aquatic resources for survival. In this episode, travel to the UNESCO World Heritage Site of Pinnacle Point in South Africa to talk with Curtis Marean, one of the foremost experts on the origins and development of coastal foraging, about how the transition from opportunistic to systematic coastal foraging may have occurred and the unexpected impact that the shift to a true coastal adaptation may have had on the development of social cooperation.
