These tiny holes that can be found on the ear are called preauricular sinuses.
While they're virtually harmless, it's still interesting to know why some of us have them and others don't.
According to
METRO, 1 in 100 people have these peculiar little holes at the part of the face that connects the face to the ear.
The preauricular sinus is much more common worldwide, where in Ethiopia the sinus' are supposed to bring luck and wealth to the owners of these particular types of sinus.
While the tiny holes look like piercings, they're not supposed to be decorated with a stud or earring as they seldomly can become infected.
It's not yet known exactly why these tiny ear holes appear but they're hereditary and develop when we are in the womb, while some claim that they are an evolutionary remnant of fish gills.
So there you go.
