The '''simians''', '''anthropoids''', or '''higher primates''' are an [[infraorder]] ('''Simiiformes''' {{IPAc-en|'|s|ɪ|m|i|.|ᵻ|f|ɔr|m|iː|z}}) of [[primate]]s containing all animals traditionally called [[monkey]]s and [[ape]]s. More precisely, they consist of the [[parvorder]]s [[New World monkey|Platyrrhini]] (New World monkeys) and [[Catarrhini]], the latter of which consists of the family Cercopithecidae ([[Old World monkey]]s in the stricter sense) and the superfamily [[Hominoidea]] (apes{{dash}}including humans).

The simians are sister group to the [[Tarsiiformes|tarsiers]] (Tarsiiformes), together forming the [[Haplorhini|haplorhines]]. The [[Evolutionary radiation|radiation]] occurred about 60 million years ago (during the [[Cenozoic era]]); 40 million years ago, simians colonized [[South America]], giving rise to the [[New World monkey]]s. The remaining simians (catarrhines) split about 25 million years ago into [[Old World monkey|Cercopithecidae]] and [[ape]]s (including [[human]]s).

==Taxonomy==
In earlier classification, New World monkeys, Old World monkeys, apes, and humans – collectively known as '''simians''' or '''anthropoids''' – were grouped under '''Anthropoidea''' ({{IPAc-en|ˌ|æ|n|θ|r|ə|ˈ|p|ɔɪ|d|i|.|ə}}; {{etymology|grc|''{{wikt-lang|grc|ἄνθρωπος}}'' ({{grc-transl|ἄνθρωπος}})|human||''{{wikt-lang|grc|-οειδής}}'' ({{grc-transl|-οειδής}})|resembling, connected to, etc.}}), while the [[Strepsirrhini|strepsirrhines]] and tarsiers were grouped under the suborder "[[Prosimii]]". Under modern classification, the tarsiers and simians are grouped under the suborder [[Haplorhini]], while the strepsirrhines are placed in suborder Strepsirrhini.<ref name="The Human Lineage">{{cite book | last1 = Cartmill | first1 = M. | last2 = Smith | first2 = F.

[[Primatology]], [[paleoanthropology]], and other related fields are split on their usage of the synonymous infraorder names, Simiiformes and Anthropoidea. According to [[Robert Hoffstetter]] (and supported by [[Colin Groves]]), the term Simiiformes has [[Principle of Priority|priority]] over Anthropoidea because the taxonomic term ''Simii'' by [[Jan van der Hoeven|van der Hoeven]], from which it is constructed, dates to 1833.<ref name=msw3/><ref name=Hoffstetter>{{Cite journal | last1 = Hoffstetter | first1 = R. | title = Phylogeny and geographical deployment of the Primates | doi = 10.1016/0047-2484(74)90028-1 | journal = Journal of Human Evolution | volume = 3 | issue = 4 | pages = 327–350 | year = 1974 | bibcode = 1974JHumE...3..327H }}</ref> In contrast, Anthropoidea by [[St. George Jackson Mivart|Mivart]] dates to 1864,<ref>{{cite book | title = Companion Encyclopedia of Anthropology: Humanity, Culture and Social Life | editor1-last = Ingold | editor1-first = T | chapter = The evolution of early hominids | last1 = Tobias | first1 = P.

He also noted that Anthropoidea is too easily confused with "anthropoïdes", which translates to "apes" from several languages.<ref name=Hoffstetter/>

Some lines of extinct simian also are either placed into the [[Eosimiidae]] (to reflect their [[Eocene]] origin) and sometimes in [[Amphipithecidae]], thought to originate in the [[Rupelian|Early Oligocene]]. Additionally, ''[[Phileosimias]]'' is sometimes placed in the Eosimiidae and sometimes categorised separately.<ref>{{cite journal| title = Anthropoid primates from the Oligocene of Pakistan (Bugti Hills): Data on early anthropoid evolution and biogeography| author = Marivaux <!---| first1=Laurent | last1=Marivaux | first2=Pierre-Olivier | last2=Antoine‡ | first3=Rafiqul Hassan Syed| last3=Baqri| first4=Mouloud | last4=Benammi | first5=Yaowalak | first5=Chaimaneet | first6=Jean-Yves | last6=Crochet | first7=Dario | last7=de Franceschi| first8=Nayyer | last8=Iqbal | first9=Jean-Jacques | last9=Jaeger | first10=Gregoire | last10=Metais†† | first11=Ghazala | last11=Roohi| first12=Jean-Loup | last12=Welcomme--->| journal = [[PNAS]]| date = June 2005 | volume = 102| pages = 8436–41 | issue = 24| doi = 10.1073/pnas.0503469102| pmc = 1150860| pmid=15937103| bibcode = 2005PNAS..102.8436M|display-authors=etal| doi-access = free}} ([http://www.pnas.org/content/102/24/8436.full.pdf Full text PDF])</ref>

== Evolution ==
The origin of anthropoid primates was initially thought to be Africa, however, fossil evidence now suggests they originated in Asia. During the middle to late [[Eocene]], multiple groups of Asian anthropoids crossed the [[Tethys Ocean|Tethys Sea]] on natural rafts or floating islands, colonizing Africa alongside other Asian mammals. The earliest African anthropoid fossils appear in sites across northern Africa, including Algeria, Libya, and Egypt. This dispersal before Africa and Asia were connected by land was aided by size, Asian monsoons, and river systems. After reaching Africa, anthropoids underwent major evolutionary changes, with some groups later crossing the South Atlantic to establish the New World monkey lineage in South America.<ref>{{Cite journal |last=Beard |first=K. Christopher |date=2016-10-21 |title=Out of Asia: Anthropoid Origins and the Colonization of Africa |url=https://www.annualreviews.org/doi/10.1146/annurev-anthro-102215-100019 |journal=Annual Review of Anthropology |language=en |volume=45 |issue=1 |pages=199–213 |doi=10.1146/annurev-anthro-102215-100019 |issn=0084-6570}}</ref>

The New World monkeys in parvorder Platyrrhini split from the rest of the simian line about 40 million years ago (mya), leaving the parvorder Catarrhini occupying the Old World. This latter group split about 25 mya between the [[Cercopithecidae]] and the apes, making Cercopithecidae more closely related to the apes than to the Platyrrhini.

''Dolichocebus annectens'' and ''Parvimico materdei'' would normally, given their South American location and their age and other factors, be considered Platyrrhini. The original Eosmiidae appear polyphyletic with ''Nosmips,'' ''Bahinia, and'' ''Phileosimias'' at different locations from other eosimians.

==Biological key-features==
In a section of their 2010 assessment of the evolution of anthropoids (simians) entitled "What is an Anthropoid", Williams, Kay, and Kirk set out [http://www.pnas.org/content/107/11/4797.full a list of biological features common to all or most anthropoids], including genetic similarities, similarities in eye location and the muscles close to the eyes, internal similarities between ears, dental similarities, and similarities on foot bone structure.<ref name="Williams"/> The earliest anthropoids were small primates with varied diets, forward-facing eyes, acute color vision for daytime lifestyles, and brains devoted more to vision and less to smell.<ref name="Williams"/> Living simians in both the New World and the Old World have larger brains than other primates, but they evolved these larger brains independently.<ref name="Williams"/>

Simians characteristically have relatively large brains, fused mandibles, binocular and color vision, and the females have a single fused uterus.<ref>Henry R. Hermann Ph.D., in Dominance and Aggression in Humans and Other Animals, 2017</ref> They also have fewer teeth and are more sexually dimorphic in terms of body size and anatomy.

The traits that separate New World simians from Old World simians are the nostrils and their dentation. New World simians have broad noses with forward facing nostrils and three premolars in each quadrant of the mouth, while Old World simians have narrower noses with downward facing nostrils and a narrow septum and only have two premolars.{{Citation needed|date=December 2024}}
