Charting the neglected West: The social system of Guinea baboons

Guinea baboons (Papio papio) exhibit a unique multi-level social organization that challenges traditional understandings of baboon society. Unlike other baboon species, they form stable reproductive units with one primary male and multiple females, which coalesce into parties and gangs with overlapping home ranges. This structure is marked by low male aggressiveness and female freedom, contrasting sharply with hamadryas baboons (P. hamadryas). Population genetic and behavioral data suggest female-biased dispersal, with females playing a pivotal role in intersexual bond formation. Female tenure varies from weeks to years, and while vocalizations resemble those of other baboon taxa, the social dynamics are distinct. This study, conducted at CRP Simenti in Niokolo-Koba National Park, Senegal, offers new insights into the diversity of primate social systems and their implications for understanding human social evolution.
