Chimps. Bonobos. Humans. We're all great apes, but that doesn’t mean we’re one happy family. This hour of Radiolab: stories of trying to live together.

Is this kind of cross-species co-habitation an utterly stupid idea? Or might it be our one last hope as more and more humans fill up the planet? A chimp named Lucy teaches us the ups and downs of growing up human, and a visit to The Great Ape Trust in Des Moines, Iowa highlights some of the basics of bonobo culture (be careful, they bite).

Check out this slideshow of Lucy's life, including the photo snapped as Janis and Lucy hugged in Gambia:
