lucy.jpgChimps. Bonobos. Humans. We're all great apes. We take a look at what happens when we all try to live together. Our main story is the haunting tale of a chimp named Lucy. When Lucy was only two days old she was adopted by a psychologist and his wife who wondered: if given the right environment, how human could Lucy become? This story and other tales of radical sharing between humans and the creatures on earth most like us.
