RNA sequencing of individuals within a wild baboon population reveals extensive power to detect functional regulatory variation, and suggests that the set of genes affected by such variation may be conserved across species.

Social interactions can have a direct effect on the composition of the gut microbiome in wild primates.

In wild baboons, a female's adverse early experiences can influence her offspring's survival years after the original adversity was experienced.

Wild baboons are an excellent model to study complex evolutionary processes such as speciation and hybridization, as well as the links between sociality, longevity and reproductive success.

Among the factors that predict fitness in wild baboons, dominance rank in males, but not in females, is the best predictor of epigenetic aging.

In baboon gut microbiota, most pairwise correlations in bacterial abundances are weak and negative, and bacterial correlation patterns are largely shared across hosts, rather than personalized to each hosts.

Studying the fecal microbiota of wild baboons helps provide new insight into the factors that influence biological aging.
