What are the motivations behind mating desires in men and women? To understand many differences and conflicts between the sexes, we must look into our evolutionary past. During this Hot Science – Cool Talks, Dr. David Buss will present a unified theory of human mating strategy using insights from a global study of human mating behavior. Buss will also discuss the latest research in the field of evolutionary psychology, including startling discoveries about the evolutionary advantages of infidelity and physical attractiveness. Evolutionary psychology is a hybrid discipline that draws insights from modern evolutionary theory, biology, cognitive psychology, anthropology, economics, computer science, and paleoarchaeology.
