From the author of the widely acclaimed Why Zebras Don't Get Ulcers, an enlightening perspective on the peculiar drives and intrinsic needs underlying human behavior, and how they link us to -- and separate us from -- the rest of the animal kingdom.In this wide-ranging collection of witty essays, Robert M. Sapolsky brings a touch of humor and compassion to the world of cutting-edge science. His subjects range from explanations of the neurological bases of human individuality to discussions about the philosophical and political implications of recent findings in biological research. Ultimately, Sapolsky confirms that human beings are -- with unnerving frequency -- just another kind of primate."Sapolsky is one of the best scientist/writers of our time....What emerges in these brilliant, wide-ranging essays is a rich picture of human individuality and how it is both constrained and liberated by biological fate". -- Oliver Sacks, M.D.
