Anthropoidea

We have a significantly higher brain-to-body mass ratio, particularly in the visual cortex, which helps us process complex social cues.

Unlike their "lower primate" relatives (the strepsirrhines), anthropoids have several unique evolutionary traits: anthropoidea

While the broader primate world includes lemurs and lorises, anthropoids are distinguished by their larger brains, complex social lives, and flat-faced features. Here is a look at what makes this branch of the evolutionary tree so special. We have a significantly higher brain-to-body mass ratio,

The Anthropoidea are generally split into two major groups based on where they evolved: particularly in the visual cortex

Found in Central and South America, these monkeys often have flat, broad noses and prehensile tails that act like a fifth limb.
