Here's The Reason Why Some People Have A Small Hole Above Their Ear
You might have noticed some people, who have a barely noticeable small hole, just at the top of their ear cartilage that meets their face. Believe it or not, they are not the signs of piercings or some other body modifications. Actually, such people have this type of hole from their birth, or it can be a natural mutation as well.
According to a study, only 0.1 percent of the population in the US are born with this difference. While in the UK, it is found to be 0.9 percent. Whereas in Asia and other parts of Africa, this count is between 4 to 10 percent.
This birth defect is actually called as preauricular sinus, that was first documented in 1864 by Van Heusinger. According to one evolutionary biologist, Neil Shubin, these tiny holes could be an "Evolutionary remnant of fish gills."

Generally, having a preauricular sinus is not a big deal. Although, being harmless in itself, it can be susceptible to infection or to form a cyst. Therefore, its treatment is necessary which involves either draining the sinus or removing it completely. Often these holes can occur on just one ear or both, but the researchers have proved that it's common on the right side.
