Why does nothing turn a baby’s head more quickly from nursing or playing than a passing dog or cat? How did a wolf pup taken into an Ice Age cave learn to keep coming back? Why do skittish herd animals like horses form such devoted bonds with riders that a twitch of the rein can send them into battle or fire? Made for Each Other is the first book to lay out both sides of this deep mutual connection. Drawing on the fascinating work of scientists in a wide range of fields-from behavioral psychology and neuroscience to zoology and anthropology-as well as her own investigations, Meg Daley Olmert explores the evolution and hormonal basis of biophilia, and its great importance to our well-being. Her compelling and original work also asks what happens to us when this bond is severed, when animals become mere products to be “harvested” in far-off, impersonal industries.
