Final answer:
The subfamily Cercopithecidae represents Old World monkeys, like macaques and baboons. It is a part of the Haplorrhini, a suborder of primates that includes Old World monkeys, New World monkeys, tarsiers, apes, and humans. The Hominoidea superfamily includes gibbons, great apes, and Homo and related fossil forms.
Step-by-step explanation:
Subfamily Cercopithecidae, also referred to as Old World monkeys, include particular kinds of monkeys like macaques and baboons, not humans and apes, nor all primates. The Haplorrhini, a suborder of primates, contains the tarsiers, New World monkeys, Old World monkeys, apes, and humans. Hominoidea, a superfamily of the primate infraorder Simiiformes, includes gibbons, great apes, and humanlike primates, including Homo and related fossil forms. Meanwhile, Order Primates are polarized into two groups: prosimians and anthropoids, wherein, prosimians encompass the bush babies of Africa, the lemurs of Madagascar, and the lorises, pottos, and tarsiers of Southeast Asia. Anthropoids accommodate monkeys, lesser apes, and great apes.
