Final answer:
Prosimians evolved before monkeys.
Step-by-step explanation:
The first prosimians evolved before the monkeys. This statement is true.
Prosimians are a group of primates that include lemurs, lorises, and tarsiers. They are considered to be the most primitive primates and are believed to have evolved around 60 million years ago.
Monkeys, on the other hand, evolved later than prosimians, around 40 million years ago. Monkeys are more advanced primates and include both New World monkeys and Old World monkeys.
