Chimps. Bonobos. Humans. We're all great apes, but that doesn’t mean we’re one happy family. This episode, a mashup of content stretching all the way back to 2010, asks the question, is 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).
