While the popular animal rights movement gains ever-increasing momentum, in the courts the dark ages prevail. The evolution of law that has brought fundamental rights to the most defenseless humans has yet to begin for other species. A human lost in a permanent vegetative state enjoys a large array of legal rights. But a chimpanzeea creature who can communicate with language, count, understand the minds of others, feel a variety of emotions, live in a complex culture, and make and use toolshas no rights at all.Steven Wise, who has worked and communicated with the worlds most prominent primatologists, demonstrates that, based on the latest scientific findings, the cognitive, emotional, and social capacities of at least chimps and bonobos entitle them to freedom from imprisonment and abuse. His path-breaking, witty, and impeccably researched book has everything needed to convince judges, scientists, lawyers, and the millions of others who simply care about animals of the injustice of denying them basic legal rights.
