Episode notes
Early Primate Interest
- Robert Sapolsky decided to become a primatologist at eight years old after visiting the American Museum of Natural History.
- He could have studied other animals, but he was drawn to the primate exhibit.

- Many human challenges stem from a mismatch between our modern brains and our ancestral environment. Even agriculture and settled communities are relatively recent developments.
Testosterone's Role
- Testosterone amplifies pre-existing aggression, learned socially, rather than directly causing it. Giving monkeys testosterone increases aggression towards those lower in the hierarchy, not those above.
