Cladistically, apes, catarrhines, and extinct species such as Aegyptopithecus and Parapithecidaea, are monkeys, [citation needed] so one can only specify ape features not present in other monkeys. Unlike most monkeys, apes do not possess a tail. Monkeys are more likely to be in trees and use their tails for balance. While the great apes are ...
However the distance to six different Old World monkeys was on average 2.46, indicating that the African apes are more closely related to humans than to monkeys. The authors consider the divergence time between Old World monkeys and hominoids to be 30 million years ago (MYA), based on fossil data, and the immunological distance was considered ...
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 ...
The Old World species are divided into apes and monkeys depending on the number of cusps on their molars: monkeys have four, apes have five [72] - although humans may have four or five. [78] The main hominid molar cusp evolved in early primate history, while the cusp of the corresponding primitive lower molar (paraconid) was lost. Prosimians ...
In human genetic studies, the CHLCA is useful as an anchor point for calculating single-nucleotide polymorphism (SNP) rates in human populations where chimpanzees are used as an outgroup, that is, as the extant species most genetically similar to Homo sapiens. Despite extensive research, no direct fossil evidence of the CHLCA has been discovered.
The Hominidae (/ h ɒ ˈ m ɪ n ɪ d iː /), whose members are known as the great apes [note 1] or hominids (/ ˈ h ɒ m ɪ n ɪ d z /), are a taxonomic family of primates that includes eight extant species in four genera: Pongo (the Bornean, Sumatran and Tapanuli orangutan); Gorilla (the eastern and western gorilla); Pan (the chimpanzee and the bonobo); and Homo, of which only modern humans ...
: Scientists have recently discovered a new primate species in Myanmar’s central forest. However, the Popa langur, named after nearby Mount Popa, is tragically already on the verge of extinction.
Archaeolemuridae, another family of extinct lemurs, which are also most likely related to the family Indriidae, have many similarities to baboons and other monkeys due to their body plans, which are both adopted to arboreal and terrestrial lifestyle, giving them the nickname "monkey-lemurs" or "baboon-lemurs".
