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] Other similar basal primates were widespread in Eurasia and Africa during the tropical conditions of the Paleocene and Eocene.
The chimpanzee–human last common ancestor (CHLCA) is the last common ancestor shared by the extant Homo (human) and Pan (chimpanzee and bonobo) genera of Hominini. Estimates of the divergence date vary widely from thirteen to five million years ago. In human genetic studies, the CHLCA is useful as an anchor point for calculating single ...
New World monkeys are small to mid-sized primates, ranging from the pygmy marmoset (the world's smallest monkey), at 14 to 16 cm (5.5 to 6.5 in) and a weight of 120 to 190 g (4.2 to 6.7 oz), to the southern muriqui, at 55 to 70 cm (22 to 28 in) and a weight of 12 to 15 kg (26 to 33 lb).
Barbary macaques in Gibraltar. Coordinates: 36.132248°N 5.348875°W. This young Barbary macaque is part of a group of 25 to 70 individuals from several different monkey families in Gibraltar. Originally from the Atlas Mountains and the Rif Mountains of Morocco, the Barbary macaque population in Gibraltar is the only wild monkey population on ...
The aquatic ape hypothesis (AAH), also referred to as aquatic ape theory (AAT) or the waterside hypothesis of human evolution, postulates that the ancestors of modern humans took a divergent evolutionary pathway from the other great apes by becoming adapted to a more aquatic habitat. [1] While the hypothesis has some popularity with the lay ...
Western chimpanzee. The western chimpanzee or West African chimpanzee[1] (Pan troglodytes verus) is a Critically Endangered subspecies of the common chimpanzee. It inhabits western Africa, specifically Côte d'Ivoire, Guinea, Liberia, Mali, Senegal, Ghana, Guinea-Bissau, but has been extirpated in three countries: Benin, Burkina Faso, and Togo. [1]
The capuchin monkeys (/ ˈkæpjʊ (t) ʃɪn /) are New World monkeys of the subfamily Cebinae. They are readily identified as the "organ grinder" monkey, and have been used in many movies and television shows. The range of capuchin monkeys includes some tropical forests in Central America and South America as far south as northern Argentina.
The Barbary macaque (Macaca sylvanus), also known as Barbary ape, is a macaque species native to the Atlas Mountains of Algeria, Tunisia and Morocco, along with a small introduced population in Gibraltar. [2] It is the type species of the genus Macaca. The species is of particular interest because males play an atypical role in rearing young.
