Simian. The simians, anthropoids, or higher primates are an infraorder ( Simiiformes / ˈsɪmi.ɪfɔːrmiːz /) of primates containing all animals traditionally called monkeys and apes. More precisely, they consist of the parvorders Platyrrhini (New World monkeys) and Catarrhini, the latter of which consists of the family Cercopithecidae ( Old ...
New World monkeys' closest relatives are the other simians, the Catarrhini ("down-nosed"), comprising Old World monkeys and apes. New World monkeys descend from African simians that colonized South America, a line that split off about 40 million years ago.
Monkey is a common name that may refer to most mammals of the infraorder Simiiformes, also known as the simians. Traditionally, all animals in the group now known as simians are counted as monkeys except the apes. Thus monkeys, in that sense, constitute an incomplete paraphyletic grouping; however, in the broader sense based on cladistics, apes ...
Simians are thus distinctly closer related to tarsiers than lemurs are. Strepsirrhines bifurcated some 20 million years earlier than the tarsier - simian bifurcation. However, simians are traditionally excluded, rendering prosimians paraphyletic. Consequently, the term "prosimian" is no longer widely used in a taxonomic sense, but is still used ...
The evolutionary history of the primates can be traced back 57-90 million years. [ 1] One of the oldest known primate-like mammal species, Plesiadapis, came from North America; [ 2] another, Archicebus, came from China. [ 3] Other similar basal primates were widespread in Eurasia and Africa during the tropical conditions of the Paleocene and ...
The simians include catarrhines (Old World monkeys and apes, including humans), and the platyrrhines (New World monkeys). Haplorhini was proposed by Pocock in 1918 when he realized the tarsiers were actually sister to the monkeys rather than the lemurs, also following findings of Hugh Cuming 80 years earlier and Linnaeus 160 years earlier.

Pygmy marmoset. Pygmy marmosets are two species of small New World monkeys in the genus Cebuella. They are native to rainforests of the western Amazon Basin in South America. These primates are notable for being the smallest monkeys in the world, at just over 100 g (3.5 oz). They are generally found in evergreen and river-edge forests and are ...
