This timeline give details about the common ancestor between humans and various animals.

55 MYA - euprimates
The earliest true primates is called euprimates. One is Carpolestes simpsoni. It has grasping digits but no forward facing eyes. Another (earliest?) euprimate Teilhardina asiatica is mouse-sized, diurnal and has small eyes and were tree-living fruit eaters.

Carpolestes combines features of the earlier plesiadapiforms with primate-like and is viewed as a transitional animal .It had very primate like teeth that were highly specialized for eating flowers, seeds, and fruit. The opposable big toe gave it a grasping ability that indicates it spent most of its time climbing trees. also had a nail on its big toe, but its eyes were not forward facing, and it did not have the bone structure that would allow for specialized leaping, like some of the earliest primates. as the diversity of fruits, flowers, leaf buds, and nectar increased in the Paleocene, 65 to 55 million years ago, Carpolestes took to the trees to exploit a new food source and to avoid competition with early rodents.

40 MYA - Prosimians
Primates (order) diverge into suborders Prosimians (a primitive monkey) and Anthropoids, the latter is diurnal and herbivorous. Examples of today's prosimians are tarsiers, lemurs, lorises.

Anthropoids, The simians (infraorder Simiiformes) are the "higher primates" very common to most people: the monkeys and the apes, including humans. Simians tend to be larger than the "lower primates" or prosimians.

The simians are split into three groups. The first division is literally as wide as the Atlantic Ocean. The New World monkeys in clade Platyrrhini split from the simian line about 40 million years ago, leaving clade Catarrhini occupying the Old World. This group split about 25 mya between the Old World monkeys and the apes. Earlier classifications split the primates into two large groups: the "Prosimii" (strepsirrhines and tarsiers) and the "Anthropoidea" (simians).
