Is a ring tailed lemur monkey or related to one?

Ring-tailed lemurs are not monkeys. They are prosimians, which are more closely related to apes than monkeys.

Here's a breakdown:

* Primates are the order of mammals that includes monkeys, apes, and lemurs.

* Prosimians are a suborder within primates that includes lemurs, lorises, and galagos.

* Monkeys are a parvorder within primates.

* Apes are a family within primates.

So, while ring-tailed lemurs are primates, they are more closely related to apes than to monkeys.
