#18 – Preauricular Sinus
Isn’t that body part awesome? Like, there are people who have tiny holes just above their ears! Well, such people don’t find their preauricular sinus that much amazing as we do. These tiny sinuses are prone to infections which can sometimes get nasty and cause a lot of ear pain.
Scientists believe that these preauricular sinuses prove the existence of evolution because they are allegedly remnants of our ancestors’ gills. That’s right; our ancestors had gills, just like fish!
