Final answer:
The two infraorders of monkeys that make up Anthropoids/Haplorhini are Platyrrhini and Catarrhini.
Step-by-step explanation:
The two infraorders of monkeys that make up Anthropoids/Haplorhini are Platyrrhini and Catarrhini.
Platyrrhini, also known as New World monkeys, are exclusively found in Central and South America. They have rounded nostrils that open off to the sides and possess prehensile tails for extra support in trees.
Catarrhini, or Old World monkeys, are found in Africa and Asia. They have narrower nostrils that face downward and include cheek pouch monkeys (Cercopithecinae) and leaf-eating monkeys (Colobinae).
