Why do we do the things we do? Author and MacArthur recipient Robert Sapolsky’s game-changing new book Behave: The Biology of Humans at Our Best and Worst attempts to answer this very question, one of the deepest questions of the human species. Moving between neurobiological factors, to the sensory world of our environment and endocrinology, to tracing individual’s childhoods and their genetic makeup, to encompassing larger categories of culture, ecology, and evolution, Sapolsky considers millions of years of science to wrestle with why we ultimately do the things we do…for good and for ill. Discussing his staggering work with evolutionary biologist Amy Parish, Sapolsky takes us on an engrossing tour of the science of human behavior.
