In lieu of Weekend Select... When we gaze into the eyes of a wild animal, or even a beloved pet, can we ever really know what they might be thinking? Is it naive to assume they're experiencing something close to human emotions? Or, on the contrary, is it ridiculous to assume that they AREN'T feeling something like that? In this hour of Radiolab, we explore what science can say about what goes on in the minds of animals. Guests include: a humpback whale, Paul Thoreaux, camels, Jonah Lehrer, and a bloodthirsty leopard seal.
