Suborder Anthropoidea refers to a taxonomic group of primates that includes monkeys, apes, and humans. Some synonyms for this term include the simian suborder, simian primates, and higher primates. Other common synonyms include the Haplorrhine primates, which is a term that includes both tarsiers and anthropoids, and the catarrhine primates, which refers specifically to Old World monkeys, apes, and humans. Additionally, some scientists use the term "anthropoids" as a synonym for this group. Regardless of the term used, the suborder Anthropoidea is considered an important group for studying the evolutionary history of primates and understanding the unique characteristics that define them.
