Are we ready for parrots and dolphins to be treated as persons before the law? In this unprecedented exploration of animal cognition along the evolutionary spectrum—from infants and children to other intelligent primates, from dolphins, parrots, elephants, and dogs to colonies of honeybees—Steve Wise finds answers to the big question in animal rights today: Where do we draw the line? Readers will be enthralled as they follow Wise's firsthand account of the world's most famous animal experts at work: Cynthia Moss and the touchingly affectionate families of Amboseli; Irene Pepperberg and her amazing and witty African Grey parrot, Alex; and Penny Paterson with the formidable gorilla Koko. In many cases, Wise was able to sustain an extended conversation with these extraordinary creatures. No one with even a shred of curiosity about animal intelligence or justice will want to miss this book.
