Evolutionary relationships among primates. Humans and apes comprised a higher‐order group, Hominoidea, which is related to another higher‐order group, Cercopithecoidea, which includes macaque monkeys and other Old World monkeys. Collectively, these are the Old World anthropoid primates, or the Catarrhini. The New World anthropoids, or Platyrrhini, include primates such as marmosets, squirrel monkeys, and capuchins. The species discussed in this review are highlighted in blue. Figure modified from Preuss (2019) with permission
