While distinctly Anthropoids, some Platyrrhines maintain a few of traits that are typically represented only in Prosimians. For

Convergent evolution is the concept of two or more species evolving similar traits despite being completely unrelated to one another, including the absence of a common ancestor.

The Platyrrhines, more commonly known as "New World Monkeys", share many characteristics with the Prosimians. Some of these include:

Teeth layout
Diet
Eyesight
Sleeping habits

and more.

The Platyrrhines and the Prosimians are both nocturnal animals. Despite all other members of their family being active during the day, the Playrrhines have evolved nocturnal habits similar to that of the Prosimians. Aside from that, they feed on insects more so than fruit, which is reflected by the layout of their teeth, and have eyesight well adapted to dark conditions. All of these are traits they share with the Prosimians.

Despite being in different ecosystems and regions, and sharing no recent common ancestors, both of these species have evolved strikingly similar traits. This can be used to corroborate the theory of convergent evolution, which explains how two species can evolve very similar traits despite being unrelated.
