In this episode, Xavier Bonilla has a dialogue with Ed Hagen about evolution, mental disorders such as depression,  and suicidality. They begin talking about the power of evolution, providing a defense of evolutionary psychology and the evolutionary history of humans. They discuss the evolutionary model for mental health disorders, the clinical taxonomy of the DSM-5, and defining depression. They provide some criticism of the new prolonged grief disorder, discuss the epidemiological data on depression, and explain the evolutionary model for understanding postpartum depression. They also discuss suicidality and some of the cross-cultural elements of mental disorders.
