Nature & Nurture #119: Dr. Edward Hagen - Evolutionary Anthropology, Sex Differences, & Drugs

Dr. Edward Hagen is a Professor of Evolutionary Anthropology at Washington State University, where he directs the Bioanthropology Lab. 

In this episode, Ed and I discuss the recent controversy of the American Anthropological Association’s decision to censor a conference panel on sex differences, the reality and importance of understanding sex differences in evolutionary anthropology and biology research, and the complexity of sex beyond the binary, such as in the case of intersex disorders and different and conflicting gender norms cross-culturally. We then move on to discuss Ed’s research on the evolution of substance use, including humans’ bizarre taste for spices and bitter plant toxins such as coffee and tobacco. We also talk about the evolutionary advantages and disadvantages for the use of other psychoactive drugs, such as hallucinogens, the evolution of human intelligence, and modern computational neuroscientific theories of consciousness.
