Mama's Last Hug: Animal Emotions and What They Tell Us about Ourselves

Mama's Last Hug begins with the death of Mama, a chimpanzee matriarch who formed a deep bond with biologist Jan van Hooff. When Mama was dying, van Hooff took the unusual step of visiting her in her night cage for a last hug. Their goodbyes were filmed and went viral. Millions of people were deeply moved by the way Mama embraced the professor, welcoming him with a big smile while reassuring him by patting his neck, in a gesture often considered typically human but that is in fact common to all primates. This story and others like it form the core of de Waal's argument, showing that humans are not the only species with the capacity for love, hate, fear, shame, guilt, joy, disgust, and empathy.
