Mama's last hug

Frans de Waal discusses forty years of animal research on the social and emotional lives of primates to showcase how many animals experience emotions and feelings similar to how humans do. Differentiates between feelings and emotions, and argues that humans are not the only species capable of exhibiting complex emotions. Discusses facial expressions and gestures once thought to be distinctly human but are now recognized as universal signals of feeling and emotion, which in turn raises questions about the universal nature of free will and animal sentience. Specifically looks at the chimpanzee Mama who formed a significant bond with a biologist and whose emotional and intelligent responses helped inspire similar animal research.
