Primatologist Joan Silk has spent decades following individual baboons from birth to death, documenting how friendships, conflicts, and early life experiences shape their lives. In this conversation, we explore how grooming, coalition support, and even simple grunts help baboons repair fights and maintain social bonds. We talk about why female baboons have intense relationships with their mothers but more contentious bonds with sisters, what happens hormonally when a close partner dies, and how early adversity can make it harder to form strong social ties later on.
We also draw parallels to human life: bullying and social exclusion, the energy cost of maintaining friendships, the vulnerability of pulling back during hard times, and the moment when a relationship moves beyond tit‑for‑tat reciprocity into something more stable. If you’re curious about the biology of friendship, the psychology of conflict repair, and why our social worlds matter for how long we live, this episode is for you.
