Despite the fact we all have them, somehow we're all a bit fascinated by the tiny pigmented areas of skin known as nipples. But sexualization aside, nipples actually serve an essential evolutionary purpose of feeding babies. So for the 99% of us who aren't currently breastfeeding, and for the 50% of us who never will, their purpose is often called into question.
We've shed some light on the matter:
1. Chandler's third nipple isn't so odd after all
It's actually perfectly normal to have more than two nipples. Some notable personalities with extra nipples include Lily Allen who apparently has three, and Harry Styles, who's reported to proudly boast about having four of them.
2. Why do men have them?
With no biological purpose to men's nipples, it makes you wonder why they still have them. It's because all embryos actually begin to grow as females, and it's not until after nipple development that fetuses with the male Y-chromosome differentiate into boys, while embryos with the X chromosome develop into girls.
