Temporal range: Early Eocene–Present
|Tarsiers are prosimian primates, but more closely related to monkeys, apes, and humans (simians) than to other prosimians.|
|Suborder:||Prosimii not used in |
Prosimians are a group of proto-primates. It includes all living and extinct strepsirrhines (lemurs, lorises, and adapiforms), as well as the haplorhine tarsiers and their extinct relatives, the omomyiforms.
Prosimians are a paraphyletic group and not a clade (a group of an ancestor and all its descendants). Tarsiers share a more recent common ancestor with all simians than with the strepsirrhines. Consequently, the term "prosimian" is no longer an official term in taxonomy. It is still used to compare their behaviour with that of other primates.
Prosimians are the only primates native to Madagascar, but are also found throughout Africa and in Asia.

- The division of the order Primates into two evolutionary grades, Prosimii ("lower primates") and Anthropoidea ("higher primates") is sometimes used, but has been shown through morphological and genetic evidence to be incorrect. Alternatively, a three-way split in the order Primates—Prosimii, Tarsiiformes, and Anthropoidea—has also been suggested.
