Though the Lucy experiment would largely be called a failure, could there be a way to re-do it... but better? Producer Soren Wheeler visits The Great Ape Trust in Des Moines, Iowa, to meet Kanzi the bonobo. Dr. Sue Savage-Rumbaugh uses lessons learned from her time with Lucy in her current research with great apes, and Bill Fields explains the basics of bonobo-human communication, and ruminates on the differences between bonobo culture and our own, as illustrated by a swift and painful bite to his hand.
