From the bestselling author of A Primate's Memoir and Determined: A Science of Life Without Free Will comes a landmark, genre-defining examination of human behavior and an answer to the question: Why do we do the things we do?Behave is one of the most dazzling tours d’horizon of the science of human behavior ever attempted. Moving across a range of disciplines, Sapolsky—a neuroscientist and primatologist—uncovers the hidden story of our actions. Undertaking some of our thorniest questions relating to tribalism and xenophobia, hierarchy and competition, and war and peace, Behave is a towering achievement—a majestic synthesis of cutting-edge research and a heroic exploration of why we ultimately do the things we do ... for good and for ill.
