Primates

Primates are among the most social of all animals, forming pairs or family groups, uni-male harems, and multi-male/multi-female groups. Non-human primates have at least four types of social systems, many defined by the amount of movement by adolescent females between groups. Primates have slower rates of development than other similarly sized mammals, reach maturity later, and have longer lifespans. Primates are also the most cognitively advanced animals, with humans (genus Homo) capable of creating complex languages and sophisticated civilizations, while non-human primates have been recorded using tools. They may communicate using facial and hand gestures, smells and vocalizations.
