What are the basic rules of baboon society?
Chacma baboons live in complex, hierarchical social groups, with a dominant alpha male and female at the top, and subordinate members below. Female baboons are born into their rank, which remains static for their whole lives, and is passed down to their offspring. As they approach adulthood, males will either find their rank in their home troop through challenges for dominance, or leave the troop and attempt to join another. The reign of an alpha male is relatively short-lived, shifting to another male every 2 to 5 years on average, although this can vary depending on the troop and the circumstances. The longer the tenure of the alpha male, the more stable and less stressed the troop is.
The troop forages together. Dominant individuals monopolise the best food, and do not share it with others, even their own infants.
The group relies on vigilant sentinels to protect and warn against predators. They will attempt to flee from danger, but if attacked, the whole troop will fight back against an aggressor, with males leading the vanguard.
Baboon are caring parents – both the mother and father provide nurturing and protection for their offspring. Aunties and platonic male friends of the mother also help out with child care.
Strong social bonds are reinforced daily through communicating, grooming and playing, with alliances playing a key role in maintaining relationships and navigating conflicts.
