Phylogenetic tree of the primates Notharctus. The evolutionary history of the primates can be traced back 57-90 million years. [1] One of the oldest known primate-like mammal species, Plesiadapis, came from North America; [2] another, Archicebus, came from China. [3]
Together with Paralouatta marianae from Cuba, it is the oldest known New World monkey of North America. [2] Fossils of Panamacebus, a left upper first molar and lower premolar, [3] were uncovered from the Las Cascadas Formation, of which tuffs were analyzed providing an age of 20.93 ± 0.17 Ma, [4] of the Panama Canal Zone.
The red-tailed monkey associates with several species, including the western red colobus, blue monkey, Wolf's mona monkey, mantled guereza, black crested mangabey and Allen's swamp monkey. [111] Several of these species are preyed upon by the common chimpanzee.
This suggests the primitive platyrrhine ancestors of Branisella came to South America from Africa. Other features, however, suggest that it may have been related to the omomyids, an extinct group of tarsier-like primates found in North America, among other places. [5] Branisella has an estimated body mass of 1,000 g (35 oz). [1]
Old World monkeys are primates in the family Cercopithecidae (/ ˌ s ɜːr k oʊ p ɪ ˈ θ ɛ s ɪ d iː /). 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).
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 ...
Omomyidae is a group of early primates that radiated during the Eocene epoch between about (mya). Fossil omomyids are found in North America, Europe & Asia, making it one of two groups of Eocene primates with a geographic distribution spanning holarctic continents, the other being the adapids (family Adapidae).
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 ...
