Described by Oliver Sacks as 'one of the best scientist-writers of our time', Robert M. Sapolsky here presents the human animal in all its quirkiness and diversity. In these remarkable essays, Sapolsky once again deploys his compassion and insights into the human condition to tell us who, why and how we are. "Monkeyluv" touches on themes such as sexuality, aggression, love, parenting, religion, ageing, and mental illness. He ponders such topics as our need to seek out beauty; why our preferences in food become fixed; why we are sexually attracted to one another; why Alzheimer's disease tends to be a post-menopausal phenomenon; and why grandmothers buying groceries for their grandchildren are part of nature's Darwinian logic.
