* Monkeys have tails, apes do not.
Here's a breakdown:
Monkeys:
* New World Monkeys: Found in Central and South America. Have prehensile tails (tails that can grasp).
* Old World Monkeys: Found in Africa and Asia. Have non-prehensile tails (tails that cannot grasp).
Apes:
* Great Apes: Include gorillas, chimpanzees, bonobos, orangutans, and humans.
* Lesser Apes: Include gibbons and siamangs.
So, while monkeys and apes share a common ancestor, they have evolved along different paths, resulting in distinct physical characteristics.
