eli5: How do other animals produce more than 1 baby at a time?

Question

This is a pretty broad question so let me explain:

I obviously know how human babies are made, sperm goes into the egg and develops into a baby. Sometimes more than one baby can come out of the egg splits after fertilization or if two seperate eggs are fertilized at the same time. How do other animals produce more than one baby (like cats, rodents, etc)? Is it the same process?

Answer 1

probably due to evolutionary shenanigans, If an animal gives birth to more offspring at once, there is a greater chance that one of them will survive and pass it on over the generations
