COVER Lanjo, a 25-year-old male chimpanzee living in the Kanyawara community in Kibale National Park, Uganda. Long-term observations show that wild chimpanzees, like humans, increasingly prioritize strong, mutual social bonds and positive social interactions during the aging process. Social selectivity in our close relatives reveals the evolutionary roots of successful social aging. See pages 403 and 473.
