Only Humans Have Chins
We share many similarities with other animals, especially our cousin, the chimp. But, we have one feature that no other animal in the world has- chins. The chin is a specific term for the little piece of bone that extends from the jaw. It isn’t just a lower part of your face.
Even though it may seem odd, humans are the only animals with a chin. Researchers have postulated that we developed chins to help us when we chew.
