Guest: Frans de Waal
It was long believed that our emotions set us apart from other animals – we alone felt genuine joy, guilt, hate, envy and grief. But renowned primatologist FRANS DE WAAL says that researchers are now learning just the opposite, that all kinds of animals have rich emotional lives. De Waal, director of the Living Links Center at the Yerkes National Primate Research Center at Emory University, details what we know about the complexity of animal emotions in his new book, Mama’s Last Hug. He comes in to share stories about happy rats, hopeful pigs, and empathetic chimpanzees and talk about what we can learn about ourselves from animals.
