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?
In: Biology
Same process, but evolution made it so that some animals produce larger numbers of babies. Animals which in the wild have a high infant mortality rate need to produce enough babies so that there is a good chance that 1 or 2 will survive to adulthood. Similar animals that couldn’t do that went extinct.
