Primates

About Primates

  • A primate is any member of the biological order Primates, the group that contains all the species commonly related to the lemurs, monkeys, and apes, with the latter category including humans. Primates are found all over the world.
  • Non-human primates occur mostly in Central and South America, Africa, and southern Asia.
  • A few species exist as far north in the Americas as southern Mexico, and as far north in Asia as northern Japan.
  • The Primates order is divided informally into three main groupings: prosimians, monkeys of the New World, and monkeys and apes of the Old World.
  • All primates have five fingers (pentadactyly), a generalized dental pattern, and a primitive (unspecialized) body plan.
  • Another distinguishing feature of primates is fingernails.
  • Opposing thumbs are also a characteristic primate feature, but are not limited to this order; opossums, for example, also have opposing thumbs.

  • Chimpanzees walk on all fours and have longer arms than legs. They are called “knuckle walkers” because they use their knuckles for support.
  • Humans and chimpanzees share 95 to 98 percent of the same DNA. Biologically, chimpanzees are more closely related to humans than they are to gorillas.

Bonnet macaques likely play a role in tree propagation by dispersing seeds throughout the forest floor.
