Meet the Cookes: There's mom and dad, brother Lowell, and sisters Fern and Rosemary. They're all from the same scientific sub-family, but Fern is a chimp, and one day she disappears. This hour we'll talk to the author of a new novel about living with an ape, and then to two people with real-life experience protecting and researching our closest ancestors.

Guests:

Karen Joy Fowler, author of We Are All Completely Beside Ourselves

Dr. Sally Boysen, professor of psychology at Ohio State

Amy Fultz, co-founder and behavior director at Chimp Haven sanctuary
