Have you ever noticed that some people have a tiny hole next to their ear? It almost looks like a piercing or a little scar, but it’s actually a genetic mark that appears while the fetus is developing.
You might never have seen one of these little holes before, but between 1 and 10% of the population has them. The holes are also hereditary, so if you do have one, then there’s a chance your kids will have them too.
The feature itself is known as the perauricular sinus. It always appears in the same place, but why? Well, read on to learn the full explanation.
Usually found on the right ear, these little holes are more common in certain countries and ethnicities.
The holes sometimes appear more like raised bumps, in which case they are called perauricular cysts, and may be removed via surgery. These cysts aren’t normally dangerous, but they can be a good place for bacteria to grow.
The feature is genetic and forms while the baby is developing inside the mother’s uterus. Despite being a genetic “defect”, many people think the perauricular sinus is a pretty cute feature.
These little holes are particularly prevalent in people with Asian or African backgrounds. In those parts of the world, up to 10% of the population is estimated to have the perauricular sinus.
They are various legends and myths tied to the feature, with some cultures believing that it helps to attract good fortune and money.
A more scientific explanation is that the hole is a sign of evolution; a throwback to the times when we had gills.
Some people even have a perauricular sinus on both ears! This is especially rare.
For now, scientists still aren’t sure why these holes appear, but there are certainly some interesting theories out there!
