I love monkeys or primates , there are about 260 known species of them.
if you ask me my ex boyfriend was a monkey
They are cute though. and considered intelligent , particularly Old World monkeys.
Remember in the 90's when everyone had pet chimpanzees and they got mauled by them
As a pet , not a good idea. They are also called Simians with tails emerged 60 million years ago.
so they never really had tails before?
Some are and some aren't . There are 2 types , new world and old world 
oh okay sorry, and the only difference is the tails?
