The mandrill has a stocky body with a large head and muzzle, as well as a short and stumpy tail. [19] The limbs are evenly sized and the fingers and toes are more elongated than those in baboons, [20] with a more opposable big toe on the feet. [21] The mandrill is the most sexually dimorphic primate, [22] and it is the largest monkey. [23]
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 ...
The tail varies among each species, which can be long, moderate, short or totally absent. [6] Although several species lack tails, and their common names refer to them as apes, these are true monkeys, with no greater relationship to the true apes than any other Old World monkeys. Instead, this comes from an earlier definition of 'ape' that ...
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 ...
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 ]
However, humans and our closest primate relatives — the great apes — said farewell to tails about 25 million years ago, when the group split from Old World monkeys.
Most Old World monkeys have tails (the family name means "tailed ape"), unlike the tailless apes. The tails of Old World monkeys are not prehensile, unlike those of the New World monkeys (platyrrhines). The distinction of catarrhines from platyrrhines depends on the structure of the rhinarium, and the distinction of Old World monkeys from apes ...
The order Primates consists of 505 extant species belonging to 81 genera. This does not include hybrid species or extinct prehistoric species. Modern molecular studies indicate that the 81 genera can be grouped into 16 families; these families are divided between two named suborders and are grouped in those suborders into named clades, and some of these families are subdivided into named ...
