Field studies of natural mammal populations present powerful opportunities to investigate
the determinants of health and aging using fine-grained observations of known individuals …

Genetic admixture is central to primate evolution. We combined 50 years of field
observations of immigration and group demography with genomic data from~ 9 generations …

For more than 70 y researchers have looked to baboons (monkeys of the genus Papio) as a
source of hypotheses about the ecology and behavior of early hominins (early human …

Adverse conditions in early life can have negative consequences for adult health and
survival in humans and other animals. What variables mediate the relationship between …

Affiliative social behaviors are linked to fitness components in multiple species. However,
the role of genetic variance in shaping such behaviors remains largely unknown, limiting our …

Objectives In many taxa, adverse early‐life environments are associated with reduced
growth and smaller body size in adulthood. However, in wild primates, we know very little …

Does social isolation in adulthood predict survival because socially isolated individuals are
already unhealthy due to adversity earlier in life (health selection)? Or do adult social …

Objectives Pregnancy failure represents a major fitness cost for any mammal, particularly
those with slow life histories such as primates. Here, we quantified the risk of fetal loss in …

Population genetic theory, and the empirical methods built upon it, often assume that
individuals pair randomly for reproduction. However, natural populations frequently violate …

There is a growing consensus that hybridization played a vital role in shaping past and
present primate diversity. Analyses of contemporary and ancient DNA suggest that genetic …
