This podcast episode explores the concept of the "male norm" in biological and medical research, where the female body has been largely excluded. It discusses the implications of this exclusion, including a limited understanding of human evolution, a lack of knowledge about how drugs and treatments affect women, and health disparities between men and women. The episode also delves into the evolution of the female body, including the role of milk in human development and the evolutionary significance of invasive pregnancies. The speakers challenge the belief in significant structural or functional differences between male and female brains and emphasize the importance of recognizing both biological and social factors in gender development. The episode concludes by discussing the nature of sexism and its evolutionary origins, as well as the importance of understanding the female body's evolutionary history.
