Alamin Kung Anong Ibig Sabihin Ng Isang Butas Sa Iyong Tenga!


Evolution has come a long way for many animals, including us humans.

Our ability to walk upright, our hands used to grip objects, and even our well-developed brain all came from natural selection and evolution. That is if you believe Charles Darwin.

But even after years and years of evolution, some traits still remain to be part of the human anatomy.

One such trait is a tiny hole near the ear that is present in less than 1% of the world's population.

It's not there as a mere accident. In fact, medical professionals even have a proper name for it. This tiny hole is better known as the preauricular sinus.

The preauricular sinus is a hereditary birth defect that was first documented in 1864 by scientist Van Heusinger. 50% of the people with this sinus either have it in one ear or both.

According to Neil Shubin, an evolutionary biologist, this preauricular sinus may be an evolutionary  remnant of fish gills.

But if you are part of the few who actually have this extra trait, there is nothing to worry about.

These may or may not be linked to other things, but it's definitely not harmful. The worst that could happen is that they may get infected, just like any hole in the body. But it's nothing that a few doses of antibiotics can't fix.

So there! The preauricular sinus is just a quirky part of the body. It looks like a pre-made piercing but don't you dare put a piercing on it!
