Primatologist Aaron Sandel discusses the social dynamics of chimpanzees and their parallels to human behavior.
Primatologist Aaron Sandel has spent over a decade studying the Ngogo chimpanzees, witnessing one of the largest known chimp communities split into two factions. In this episode, Aaron joins Brené and Adam to explore what chimpanzees can teach us about friendship, conflict, belonging, and human nature. He shares what he learned from watching these chimps show affection, navigate dominance hierarchies, and face the effects of division within their own community. Aaron also reflects on what it was like to watch chimps he knew by name turn against one another, while exploring the surprising depth of bonds between chimpanzees. Together, they explore the parallels between chimpanzee behavior and the ways we harmonize, polarize, and build communities in our own lives.
