Primates is the name of the order of mammals to which we happen to belong. The name means 'first' or 'most important' and was given to the order by Carl Linnaeus. While naming it that way may have been a matter of human ego, we can't help but feel a certain fascination with the group to which we belong.
Primates typically have grasping hands and feet in addition to relatively large brains. They have flatter faces than most other mammals, lacking the muzzle of dogs, bears, deer and other mammals. They have good vision but a more limited sense of smell than most other mammals. Most are highly social.
