This is in contrast with Old World Anthropoids, including gorillas, chimpanzees, bonobos, siamangs, gibbons, orangutans, and most humans, which share a dental formula of 2.1.2.3 2.1.2.3. Many New World monkeys are small and almost all are arboreal , so knowledge of them is less comprehensive than that of the more easily observed Old World monkeys.
[citation needed] Like the platyrrhines, the catarrhines are generally diurnal, [20] and have grasping hands and (with the exception of bipedal humans) grasping feet. The apes – in both traditional and phylogenic nomenclature – are exclusively catarrhine species.
Brown spider monkey (Ateles hybridus) Platyrrhini is a parvorder of primates. Members of this parvorder are called platyrrhines, or New World monkeys, and include marmosets, tamarins, and capuchin, squirrel, night, titi, saki, howler, spider, and woolly monkeys. Platyrrhini is one of three clades that form the suborder Haplorrhini, itself one of two suborders in the order Primates. They are ...
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.
Human evolution is the evolutionary process within the history of primates that led to the ... and to the anthropoids, which are the Platyrrhines or New World ...
In earlier classification, New World monkeys, Old World monkeys, apes, and humans – collectively known as simians or anthropoids – were grouped under Anthropoidea (/ ˌ æ n θ r ə ˈ p ɔɪ d i. ə /; from Ancient Greek ἄνθρωπος (ánthrōpos) 'human' and -οειδής (-oeidḗs) 'resembling, connected to, etc.'), while the strepsirrhines and tarsiers were grouped under the ...
Range and density of non-human primates. Primates is a diverse order of placental mammals which includes monkeys, lemurs, galagos, lorisids, tarsiers, and apes (including humans). Members of this order are called primates. The order currently comprises 505 extant species, which are grouped into 81 genera. The majority of primates live in South ...
The most important (and often only important for discussions of opsin evolution) parameter of the spectral sensitivity is the peak wavelength, i.e. the wavelength of light to which they are most sensitive. For example, a typical human L-opsin has a peak wavelength of 560 nm. The cone complement defines an individual's set of cones in their ...
