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 encephalization quotient of some cetaceans is therefore higher than that of most primates, including the nearest relatives of humans, such as Australopithecus. [8] This list follows partly from Walter Carl Hartwig's 2002 book The Fossil Primate Record [9] and John G. Fleagle's 2013 book Primate Adaptation and Evolution (3rd edition). [10]

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).
Notharctinae is an extinct subfamily of primates that were common in North America during the early and middle Eocene (55-34 million years ago). The six genera that make up the group (Cantius, Pelycodus, Copelemur, Hesperolemur, Notharctus, and Smilodectes) contain species that are among the most primitive of the adapiform group, which is one of the most primitive groups of primates.

This relationship is shown by the ranks (prosimians in bold) in the list below of the current primate classification between the order and infraorder level. The term "prosimian" is considered taxonomically obsolete, [16] although it is used to emphasize similarities between strepsirrhines, tarsiers, and the early primates. [17] Order Primates
The order Primates consists of 505 extant species belonging to 81 genera. This does not include hybrid species or extinct prehistoric species. Modern molecular studies indicate that the 81 genera can be grouped into 16 families; these families are divided between two named suborders and are grouped in those suborders into named clades, and some of these families are subdivided into named ...
