[4] [3] [5] [2] [6] [excessive citations] Its sister in the infraorder Simiiformes is the parvorder Platyrrhini (New World monkeys). [2] There has been some resistance to directly designate apes (and thus humans) as monkeys despite the scientific evidence, so "Old World monkey" may be taken to mean the Cercopithecoidea or the Catarrhini.
Mandrills and baboons are monkeys; the rest of the species on this list are apes. Typically, Old World monkeys (paleotropical) are larger than New World monkeys (neotropical); the reasons for this are not entirely understood but several hypotheses have been generated. [3]
This clade, containing the Old World monkeys and the apes, diverged from a common ancestor with the New World monkeys around 45 to 55 million years ago. [ 4 ] [ need quotation to verify ] The individual species of Old World monkey are more closely related to each other than to apes or any other grouping, with a common ancestor around 14 million ...
"Ape", from Old English apa, is a word of uncertain origin. [b] The term has a history of rather imprecise usage—and of comedic or punning usage in the vernacular.Its earliest meaning was generally of any non-human anthropoid primate, as is still the case for its cognates in other Germanic languages.
The researchers compared the genomes of six species of apes, including humans, and 15 species of monkeys with tails to pinpoint key differences between the groups. Our ancient animal ancestors had ...
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 ( hypocone ) evolved in early primate history, while the cusp of the corresponding primitive lower molar (paraconid) was lost.
Western gorillas live in both lowland swamp forests and montane forests, at elevations ranging from sea level to 1,600 m (5,200 ft). [39] Western lowland gorillas live in swamp and lowland forests ranging up to 1,600 m (5,200 ft), and Cross River gorillas live in low-lying and submontane forests ranging from 150–1,600 m (490–5,250 ft).
The ID between humans and gorillas was determined to be 1.09, that between humans and chimpanzees was determined as 1.14. 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.
