What is the difference between a monkey and an ape?
The easiest way to tell them apart at first glance is to look for a tail, since monkeys have tails and apes don’t. But there are a number of differences. They have different shoulder structures, so apes are able to swing from branch to branch (as are humans) and walk on their hind legs, whereas monkeys are quadripeds. Apes have larger brains. Apes are overall more similar to humans than monkeys are. Apes are not native to the Americas, whereas certain species of monkeys are native to South America. Apes also live longer than monkeys, and there are fewer species of apes. I remember most of this from college, but here is a website with the comparisons spelled out: http://www.diffen.
