Cave 13B at Pinnacle Point, the site of intense excavation work since 2000. Curtis Marean's research here seeks to find clues about how environmental changes affect human behavior and evolution.

Curtis Marean received his Ph.D. from the University of California at Berkeley in 1990 and is now a member of the Institute of Human Origins and School of Human Evolution and Social Change at Arizona State University. In addition to studying climates and environments of the past,his research focuses on the origins of modern humans, the prehistory of Africa and the study of animal bones from archaeological sites.

Much of his recent work involves anthropological finds at Pinnacle Point, a sea cliff along the south coast of South Africa where a large number of caves overlook the Indian Ocean. In 2007, Marean and a team of researchers reported finding evidence at Pinnacle Point that suggests humans may have eaten seafood more than 40,000 years earlier than previous estimates and it may have been a catalyst for early human migration out of Africa.

In 2009, Marean and colleagues reported finding evidence from this location that early modern humans used fire in a controlled way to increase the quality and efficiency of stone tools, possibly a sign of the evolution of human brain power. In the video below, Marean uses his own brain power to answer the ScienceLives 10 Questions.
