Catarrhini

Catarrhini is the primate parvorder comprising Old World monkeys, apes, and humans. Its members share distinctive features of the nose and, in living species, a dental formula of two incisors, one canine, two premolars, and three molars per quadrant.

Simiiformes: Simiiformes is the primate infraorder containing catarrhines and New World monkeys. Catarrhini is one of the two major branches within this broader group of anthropoid primates.
Cercopithecoidea: Cercopithecoidea is the catarrhine superfamily containing Old World monkeys. It represents the monkey branch of living catarrhines, distinct from apes.
Aegyptopithecus: Aegyptopithecus is an extinct primate genus known from Oligocene fossils in Egypt. Its fossils preserve early anthropoid features near the evolutionary background of crown catarrhines.
Hominini: Hominini is the tribe containing humans and their extinct relatives after divergence from the lineage leading to chimpanzees and bonobos. Humans are catarrhines whose lineage belongs to this more narrowly defined group.
Platyrrhini: Platyrrhini is the primate parvorder comprising New World monkeys. Its members contrast with catarrhines in features including nostril orientation and dental formula.
Hominoidea: Hominoidea is the catarrhine superfamily containing apes, including humans. It represents the ape branch of living catarrhines.
Proconsul: Proconsul is an extinct early Miocene ape genus known from fossils in Africa. Its fossils illuminate early ape evolution after the catarrhine monkey–ape divergence.
Human evolution: Human evolution is the evolutionary history of humans and their extinct relatives. It is one recent branch of the much older catarrhine evolutionary history.
Dental formula: A dental formula represents the numbers of each tooth type on one side of an animal’s upper and lower jaws. Living catarrhines typically have two incisors, one canine, two premolars, and three molars per quadrant.
Cercopithecidae: Cercopithecidae is the family of Old World monkeys, including baboons, macaques, and colobus monkeys. This family contains the diverse Old World monkeys within Catarrhini.
