We all have special traits that set us apart from one another, but not all of them are physical or big enough to be noticed at first glance.

However, if you have a good eye for detail, then you’ve probably noticed that there are some people who have a very tiny hole above their ears. Perhaps you have it too and never even realized it.

From afar, it’s easy to mistake it for a piercing, a birthmark or a scar from an injury, but it actually is something much more interesting that only a small percentage of people have.

Known as preauricular sinus or pits, the congenital malformation isn’t as common in the United States as less than one percent of the population have it. The figure is slightly higher in other parts of the world, like Asia and Africa, where four to 10 percent of people are affected.

Some cultures even have superstitions about them. In Ethiopia, it is believed that this grants a person wealth

First documented in 1864 by a scientist named Van Heusinger, preauricular sinus is basically a birth defect that occurs during the early stages of fetal development.

It’s also a hereditary trait, which means the chances of your offspring getting it are higher if you or someone you’re related to has it.
