Demographic and hormonal evidence for menopause in wild chimpanzees
Among mammals, post-reproductive life spans are currently documented only in humans
and a few species of toothed whales. Here we show that a post-reproductive life span exists …

Female chimpanzees avoid inbreeding even in the presence of substantial bisexual philopatry
Inbreeding (reproduction between relatives) often decreases the fitness of offspring and is
thus expected to lead to the evolution of inbreeding avoidance strategies. Chimpanzees …

Female chimpanzee associations with male kin: trade-offs between inbreeding avoidance and infanticide protection
A large body of literature demonstrates the adaptive benefits of social relationships between
kin, including fitness and survival. Given that most social mammals are characterized by …
