Cercopithecidae Hylobatidae Hominidae
Catarrhini is a
parvorderof the Primates, one of the three major divisions of the suborder Haplorrhini. It contains the Old World monkeys ( superfamilyCercopithecoidea, family Cercopithecidae) and the apes (superfamily Hominoidea). The latter is further divided into the lesser apes (family Hylobatidae), consisting of the gibbons; and the hominids or great apes (family Hominidae), consisting of the orangutans, gorillas, chimpanzees, and humans. Older references described humans and their most close extinct relatives/ancestors as a family on its own and placed the great apes in the family Pongidae. The other two major divisions of the suborder Haplorrhini are the prosimian tarsiers, which were formerly classified with the strepsirrhines, and the Platyrrhini( New World monkeys), which live in both South Americaand Central America.
Catarrhini means narrow nose, and the term describes their narrow, downward pointing nostrils. Unlike the platyrrhini, they are generally diurnal and their tails (if they have tails at all) are not
prehensile. They have flat fingernails.

Most species show considerable
sexual dimorphismand do not form a pair bond. Most, but not all, species live in social groups. They are all native to Africaand Asia.
Classification and evolution
The apes and Old World monkeys split from their New World monkey kin about 40 million years ago. The major catarrhine division occurred about 25 mya, with the gibbons separating from the great apes and humans about 18 mya.
