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.
