Why do mammals have different nipple counts?
For example dogs and cats have more than 2 nipples while humans have only 2.
At what point in the evolution did this occured, how and why?
Also, is it possible for humans to have more than 2 nipples, in a sense that is not a rare occasion?
In: Biology
It’s based on size of a litter or babies that are typical with a species. Humans have fewer nipples than animals cuz they give birth to fewer babies
