Primate behavior refers to the social and physical actions exhibited by members of the order Primates, which includes monkeys, apes, and humans. These behaviors can range from grooming and playing to complex communication and tool use. Primates often live in social groups, which helps them establish relationships and cooperate in activities like foraging and protecting against predators. Different species of primates display unique behaviors based on their environments and social structures. For example, chimpanzees are known for their use of tools, while lemurs often engage in scent-marking to communicate. Understanding these behaviors provides insight into the evolution of social interactions and intelligence in primates.
