Greg, Liz, and Tom talk with Barbara King, Chancellor Professor of Anthropology at the College of William & Mary, and author of "How Animals Grieve." King talks about the emotional lives of animals, in particular how they express grief. Grief has been well documented in elephants and chimpanzees, but King offers examples of how ducks and even marmosets grieve over their companions.
