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

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

It is a common misconception that humans evolved from modern monkeys. In reality, we are anthropoids. We share a common ancestor with chimpanzees from about 6 million years ago. Every time you use a tool or recognize a friend’s facial expression, you are using biological "hardware" that has been refining itself within the anthropoid lineage for tens of millions of years.
