Final answer:
Among primates, chimpanzees, baboons, and gibbons are most likely to form large communities for various reasons including protection from predators, mating opportunities, and resource availability.
Step-by-step explanation:
Among primates, chimpanzees, baboons, and gibbons are most likely to form large communities.
Gorillas and chimpanzees live in family groups of approximately five to ten individuals, although larger groups are sometimes observed. Baboons, on the other hand, are known to form even larger groups, commonly consisting of around 50 individuals.
These primates form large communities for various reasons, including protection from predators, mating opportunities, and resource availability.
