Final answer:
The Suborder Anthropoidea branches off into two infraorders, Simiiformes and Tarsiiformes, with Simiiformes further dividing into Platyrrhini (New World monkeys) and Catarrhini (Old World monkeys, apes, and humans).
Step-by-step explanation:
The Suborder Anthropoidea, also known as Haplorrhini, branches off into two infraorders: Simiiformes and Tarsiiformes. The Simiiformes are further divided into Platyrrhini and Catarrhini. The Platyrrhini, also known as New World monkeys, are unique to Central and South America and are recognized by their prehensile tails and rounded nostrils. The Catarrhini, or Old World monkeys, are native to Africa and Asia, displaying narrow downward-facing nostrils. This group includes two superfamilies: Cercopithecoidea, consisting of cheek pouch monkeys and leaf-eating monkeys, and Hominoidea, which includes apes and humans. The Hominoidea are characterized by their terrestrial lifestyle and lack of tails, with examples including gibbons, chimpanzees, gorillas, orangutans, and humans.
