New World monkeys are part of the group Platyrrhini, which fossil records show appeared earlier than the groups including chimpanzees, humans, gorillas (all part of the Hominidae family), and Old World monkeys (part of the Cercopithecidae family). The divergence of New World monkeys from Old World primates is estimated to have occurred around 40 million years ago, making them one of the earliest distinct groups of primates in the fossil record.
