Why do we have Chins? + more videos |

What is the Science behind our Chins?
No Ways! There is nothing behind my Chin!
Oh ChumPum!
Firstly, it is believed that chins relieve our jaws from the stress that they encounter while chewing food.
Secondly, it is believed that our tongues may be putting a lot of stress on our jaws while speaking, now our chin may be acting as a reinforcing bone which resists that pressure.
Thirdly, it is believed that chins exist to help us attract mates.
Lastly, according to one theory, our ancestors had bigger faces, we evolved into smaller ones, and our chins are still gradually shrinking.
