Old World Monkey
Old World monkeys are primates in the family Cercopithecidae (). Twenty-four genera and 138 species are recognized, making it the largest primate family. Old World monkey genera include baboons (genus '' Papio''), red colobus (genus '' Piliocolobus''), and macaques (genus '' Macaca''). Common names for other Old World monkeys include the talapoin, guenon, colobus, douc (douc langur, genus '' Pygathrix''), vervet, gelada, mangabey (a group of genera), langur, mandrill, drill, surili ('' Presbytis''), patas, and proboscis monkey. Phylogenetically, they are more closely related to apes than to New World monkeys, with the Old World monkeys and apes diverging from a common ancestor between 25 million and 30 million years ago. 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. The individual species of Old World monkey are more closely related to each other than to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Olive Baboon
The olive baboon (''Papio anubis''), also called the Anubis baboon, is a member of the family Cercopithecidae Old World monkeys. The species is the most wide-ranging of all baboons, being native to 25 countries throughout Africa, extending from Mali eastward to Ethiopia and Tanzania. Isolated populations are also present in some mountainous regions of the Sahara. It inhabits savannahs, steppes, and forests. The common name is derived from its coat colour, which is a shade of green-grey at a distance. A variety of communications, vocal and non-vocal, facilitate a complex social structure. Characteristics The olive baboon is named for its coat, which, at a distance, is a shade of green-grey. At closer range, its coat is multicoloured, due to Agouti (coloration), rings of yellow-brown and black on the hairs. The hair on the baboon's face is coarser and ranges from dark grey to black. This coloration is shared by both sexes, although males have a mane of longer hair that tapers dow ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Douc
The doucs or douc langurs make up the genus ''Pygathrix''. They are colobine Old World monkeys, native to Southeast Asia, consisting of 3 species: red-shanked douc, black-shanked douc, and gray-shanked douc. Description The doucs are colobine Old World monkeys, which make up the genus ''Pygathrix''. They are native to Southeast Asia. Classification Even though they are known as "douc langurs", they are in fact more closely related to the proboscis monkey and snub-nosed monkeys than to any of the langurs. They are part of the subfamily Colobinae of the family Cercopithecidae Old World monkeys are primates in the family (biology), family Cercopithecidae (). Twenty-four genus, genera and 138 species are recognized, making it the largest primate family. Old World monkey genera include baboons (genus ''Papio''), red colo ....

Cladistics
Cladistics ( ; from Ancient Greek 'branch') is an approach to Taxonomy (biology), biological classification in which organisms are categorized in groups ("clades") based on hypotheses of most recent common ancestry. The evidence for hypothesized relationships is typically shared derived (phylogenetics), derived characteristics (synapomorphies) that are not present in more distant groups and ancestors. However, from an empirical perspective, common ancestors are inferences based on a cladistic hypothesis of relationships of taxa whose Phenotypic trait, character states can be observed. Theoretically, a last common ancestor and all its descendants constitute a (minimal) clade. Importantly, all descendants stay in their overarching ancestral clade. For example, if the terms ''worms'' or ''fishes'' were used within a ''strict'' cladistic framework, these terms would include humans. Many of these terms are normally used Paraphyly, paraphyletically, outside of cladistics, e.g. as a 'E ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
New World Monkey
New World monkeys are the five families of primates that are found in the tropical regions of Mexico, Central and South America: Callitrichidae, Cebidae, Aotidae, Pitheciidae, and Atelidae. The five families are ranked together as the Ceboidea (), the only extant superfamily in the parvorder Platyrrhini (). Platyrrhini is derived from the Greek for "broad nosed", and their noses are flatter than those of other simians, with sideways-facing nostrils. Monkeys in the family Atelidae, such as the spider monkey, are the only primates to have prehensile tails. New World monkeys' closest relatives are the other simians, the Catarrhini ("down-nosed"), comprising Old World monkeys and apes. New World monkeys descend from African simians that colonized South America, a line that split off about 40 million years ago. Evolutionary history About 40 million years ago, the Simiiformes infraorder split into the parvorders Platyrrhini (New World monkeys) and Catarrhini (apes and ...

Proboscis Monkey
The proboscis monkey or long-nosed monkey (''Nasalis larvatus'') is an arboreal Old World monkey with an unusually large nose (or proboscis), a reddish-brown skin color and a long tail. It is endemic to the southeast Asian island of Borneo and is found mostly in mangrove forests and on the coastal areas of the island. This species co-exists with the Bornean orangutan and monkeys such as the silvery lutung. It belongs in the monotypic genus ''Nasalis''. Taxonomy The proboscis monkey belongs to the subfamily Colobinae of the Old World monkeys. The two subspecies are: *''N. l. larvatus'' (Wurmb, 1787), which occupies the whole range of the species excluding northeast Kalimantan *''N. l. orientalis'' (Chasen, 1940), restricted to north-east Kalimantan However, the difference between the subspecies is small, and not all authorities recognise ''N. l. orientalis''. The genus name ''Nasalis'' comes from the Latin word ''nasus'' meaning "nose". This animal was made known to We ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Patas
The common patas monkey (''Erythrocebus patas''), also known as the hussar monkey, is a ground-dwelling monkey distributed over semi-arid areas of West Africa, and into East Africa. Taxonomy There is some confusion surrounding if there are valid subspecies, with some listing four, others three, and others listing two: the western ''Erythrocebus patas patas'' (with a black nose) and the eastern ''E. patas pyrrhonotus'' (with a white nose). However, it was later discovered that the nose colour used to separate these subspecies could change to white during pregnancy in females, as well as in general as animals aged, and ''E. patas pyrrhonotus'' in Kenya often did not have white noses, thus ''Mammal Species of the World'' has classified ''E. patas'' as a monotypic species. The genus status of the species has previously been in flux. Colin Groves first argued the species was closely related to '' Cercopithecus aethiops'' in 1989, based on anatomical morphology.

Presbytis
''Presbytis'' is a genus of Old World monkeys also known as langurs, leaf monkeys, or surilis. Members of the genus live in the Thai-Malay Peninsula, on Sumatra, Borneo, Java and smaller nearby islands. Description Surilis are rather small, slimly built primates. Their fur at the top is brown, grey, black, or orange, and at the lower surface whitish or greyish, sometimes also orange, with some species having fur designs at the head or at the hips.Novak, R. M. (1999). ''Walker's Mammals of the World.'' 6th edition. Johns Hopkins University Press, Baltimore. Rowe, N. (1996). ''The Pictorial Guide to the Living Primates.'' Pogonias Press, Rhode Island. Their German name of ''Mützenlanguren'' ("capped langurs") comes from the hair on their head, which forms a tuft. They differ from the other langurs by characteristics in the shape of their head (particularly the poorly developed or absent brow ridges, and the prominent nasal bones), in the teeth, and by the size of their small ...

Drill (animal)
The drill (''Mandrillus leucophaeus'') is a primate of the family Cercopithecidae (Old World monkeys), related to baboons and even more closely to the mandrill. Description The drill is a short-tailed monkey up to long, similar in appearance to the mandrill, but lacks the bright blue and red on the face of that species. It has high sexual dimorphism in weight, with males weighing up to and females up to .ARKive Drill (''Mandrillus leucophaeus'') The body is overall a dark grey-brown. Mature males have a pink lower lip and white chin on a dark grey to black face with raised grooves on the nose. The rump is pink, mauve and blue. Female drills lack the pink chin. Taxonomy Two subspecies of drill are accepted by some authorities, but are not considered distinct by others:Primate Info NetDrill/ref> * Mainland drill, ''Mandrillus leucophaeus leucophaeus'' * Bioko drill, ''Mandrillus leucophaeus poensis'' Their closest relative is the mandrill (''Mandrillus sphinx''), found fr ...

Mandrill
The mandrill (''Mandrillus sphinx'') is a large Old World monkey native to west central Africa. It is one of the most colorful mammals in the world, with red and blue skin on its face and posterior. The species is Sexual dimorphism, sexually dimorphic, as males have a larger body, longer canine teeth and brighter coloring. Its closest living relative is the Drill (animal), drill, with which it shares the genus ''Mandrillus''. Both species were traditionally thought to be baboons, but further evidence has shown that they are more closely related to white-eyelid mangabeys. Mandrills mainly live in tropical rainforests but will also travel across savannas. They are Diurnality, active during the day and spend most of their time on the ground. Their preferred foods are fruit and seeds, but mandrills will consume leaves, piths, mushrooms, and animals from insects to juvenile bay duiker. Mandrills live in large, stable groups known as "hordes" which can number in the hundreds. Femal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Langur
The Colobinae or leaf-eating monkeys are a subfamily of the Old World monkey family that includes 61 species in 11 genera, including the black-and-white colobus, the large-nosed proboscis monkey, and the gray langurs. Some classifications split the colobine monkeys into two tribes, while others split them into three groups. Both classifications put the three African genera '' Colobus'', '' Piliocolobus'', and '' Procolobus'' in one group; these genera are distinct in that they have stub thumbs (Greek κολοβός ''kolobós'' = "docked"). The various Asian genera are placed into another one or two groups. Analysis of mtDNA confirms the Asian species form two distinct groups, one of langurs and the other of the "odd-nosed" species, but are inconsistent as to the relationships of the gray langurs; some studies suggest that the gray langurs are not closely related to either of these groups, while others place them firmly within the langur group. Characteristics Colobines are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mangabey
Mangabeys are West African Old World monkeys, with species in three of the six genera of tribe Papionini. The more typical representatives of '' Cercocebus'', also known as the white-eyelid mangabeys, are characterized by their bare, upper eyelids, which are lighter than their facial skin colouring, and the uniformly coloured hairs of their fur. Members of '' Lophocebus'', the crested mangabeys, tend to have dark skin, eyelids that match their facial skin, and crests of hair on their heads. A new species, the highland mangabey, was discovered in 2003 and was initially placed in ''Lophocebus''. The genus '' Rungwecebus'' was later created for this species. ''Lophocebus'' and ''Cercocebus'' were once thought to be very closely related, so much so that all the species were in one genus, but the species within genus ''Lophocebus'' are now thought to be more closely related to the baboons in genus '' Papio'', while the species within genus ''Cercocebus'' are more closely related to ...
