A cladogram of the primates, showing a monophyletic taxon: the simians (in yellow); a paraphyletic taxon: the prosimians (in cyan, including the red patch); and a polyphyletic group: the night-active primates, i.e., the lorises and the tarsiers (in red). A cladogram of the vertebrates showing phylogenetic groups.
Other similar basal primates were widespread in Eurasia and Africa during the tropical conditions of the Paleocene and Eocene. Purgatorius is the genus of the four extinct species believed to be the earliest example of a primate or a proto-primate, a primatomorph precursor to the Plesiadapiformes, dating to as old as 66 million years ago.
Cladogram of modern primate groups; all tarsiers are haplorhines, but not all haplorhines are tarsiers; all apes are catarrhines, but not all catarrhines are apes; etc. The relationship between clades can be described in several ways: A clade located within a clade is said to be nested within that clade.
The primates are solitary creatures, and adults usually live alone. They eat forest foods, leaves and fruits. As they often have to roam large spaces to find food, it’s better for them if they ...
A primate is a member of the biological order Primates, the group that contains lemurs, the aye-aye, lorisids, galagos, tarsiers, monkeys, and apes, with the last category including great apes. With the exception of humans, who inhabit every continent on Earth, most primates live in tropical or subtropical regions of the Americas , Africa and ...
Primate Taxonomy listed about 350 species of primates in 2001; [11] the author, Colin Groves, increased that number to 376 for his contribution to the third edition of Mammal Species of the World (MSW3). [1] However, publications since the taxonomy in MSW3 was compiled in 2003 have pushed the number to 522 species, or 708 including subspecies. [60]
Olive baboon. Primatology is the scientific study of non-human primates. [1] It is a diverse discipline at the boundary between mammalogy and anthropology, and researchers can be found in academic departments of anatomy, anthropology, biology, medicine, psychology, veterinary sciences and zoology, as well as in animal sanctuaries, biomedical research facilities, museums and zoos.

This is a list of fossil primates—extinct primates for which a fossil record exists. Primates are generally thought to have evolved from a small, unspecialized mammal, which probably fed on insects and fruits. However, the precise source of the primates remains controversial and even their arboreal origin has recently been questioned. [1]
