In Tanzania, observing a troop a baboons (monkeys, no apes) shows in how far they merit their reputation as daredevil pests. They are equally playful, inventive, eager to learn and quarrelsome. Thus they adapt rather well to changes, even man-made. The pecking-order among females is determined by birth, without primogeniture, but reflects on all family members. Males constantly fight for shifting superiority, even wandering over to other troops, but can't win harem-like exclusivity when females are in heat.
