Mama's Last Hug is a whirlwind tour of new ideas and findings about animal emotions, based on Frans de Waal's renowned studies
of the social and emotional lives of chimpanzees, bonobos and other primates. It opens with the moving farewell between Mama,
a dying 59-year-old chimpanzee matriarch, and Jan Van Hoof, who was Frans de Waal's mentor and thesis advisor. The filmed
event has since gone viral (over 9.5 million views on YouTube).De Waal discusses facial expressions, animal sentience and
consciousness, the emotional side of human politics, and the illusion of free will. He distinguishes between emotions and
feelings, all the while emphasizing the continuity between our species and other species. And he makes the radical proposal
that emotions are like organs: we haven't a single organ that other animals don't have, and the same is true for our emotions.
