According to Schrago & Russo, New World monkeys split from their Old World kin about 35 million years ago (Mya). They use the major catarrhine division between cercopithecoids and hominoids of about 25 Mya (which they argue is strongly supported by the fossil evidence), as a calibration point, and from this also calculate the gibbons separating ...
Many New World monkeys are small and almost all are arboreal, so knowledge of them is less comprehensive than that of the more easily observed Old World monkeys. Unlike most Old World monkeys, many New World monkeys form monogamous pair bonds, and show substantial paternal care of young. [24] They eat fruits, nuts, insects, flowers, bird eggs ...
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] 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 years ago. [5]
List of cercopithecoids. Cercopithecoidea is a superfamily of primates. Members of this family are called cercopithecoids, or Old World monkeys, and include baboons, colobuses, guenons, lutungs, macaques, and other types of monkeys. Cercopithecoidea contains only a single family, Cercopithecidae, and includes nearly half of the species in the ...
Protopithecus. Protopithecus is an extinct genus of large New World monkey that lived during the Pleistocene. Fossils have been found in the Toca da Boa Vista cave of Brazil, as well as other locales in the country. [1] Fossils of another large, but less robust ateline monkey, Caipora, were also discovered in Toca da Boa Vista. [2]
The hominoids are descendants of a common ancestor. Human evolution is the evolutionary process within the history of primates that led to the emergence of Homo sapiens as a distinct species of the hominid family that includes all the great apes. [ 1] This process involved the gradual development of traits such as human bipedalism, dexterity ...
Long considered sacred by many Himalayan people, the golden langur was first brought to the attention of the Western world by the naturalist Edward Pritchard Gee in the 1950s. Adult males have a cream to golden coat with darker flanks while the females and juveniles are lighter. The golden langur has a black face and a long tail up to 50 cm (19 ...
Night monkeys, also known as owl monkeys or douroucoulis[ 2] ( / duːruːˈkuːliz / ), are nocturnal New World monkeys of the genus Aotus, the only member of the family Aotidae ( / eɪˈɒtɪdiː / ). The genus comprises eleven species which are found across Panama and much of South America in primary and secondary forests, tropical ...
