Stress and Rank: What Did Baboons Teach Us?
Robert Sapolsky's decades of field work with baboons in Kenya showed that social rank and personality shape stress hormone levels. Animals in unstable hierarchies and those lacking social support tend to have higher glucocorticoids, which can harm health.
Social Lives
Baboon troops are complex societies in which females stay in their natal group and males transfer. Alliances, grooming and friendships between males and females influence reproductive success and infant survival.
Medicine
Baboons have been used for biomedical research, including xenotransplantation: in 1984 an infant known as Baby Fae received a baboon heart. The species also forms a hybrid zone with the hamadryas baboon in Ethiopia.
