Erika Milam talks about the scientific search for human nature, a project that captured the attention of paleontologists, anthropologists, and primatologists in the years after World War II. Milam is a professor of history at Princeton University. She is the author of Creatures of Cain: The Hunt for Human Nature in Cold War America (Princeton University Press, 2019).

After World War II, the question of how to define a universal human nature took on new urgency. Creatures of Cain charts the rise and precipitous fall in Cold War America of a theory that attributed man’s evolutionary success to his unique capacity for murder.
