Even though our bodies have almost the same organs the unique characteristics of all of us there is.

Next to some people’s ears, for example There is a small hole. Let’s take a look at what this small space, known in medicine as the “pre-orifice sinus,” is.

What is this strange preuricular sinus?

This opening is found in both ears in some people, but more often in one ear; it is connected to a sinus system that runs under the skin. Only 1% of people in the world have it Preauricular sinus forms in the uterus.

Especially a small scar that looks like a piercing scar In people of African and Asian descent widespread. 0.1% is in the US and 0.9% in the UK.

American evolutionary biologist Neil Shubin says this hole is evolutionary evidence of many years of fish fins inside our bodies.

This small hole, although harmless in itself, is prone to infection, but is often with the simple use of antibiotics can heal.

The hole arises from the first and second pharynx (the starting points of head and neck development). This, Found in all vertebrates, originate during embryonic development a structure.

As mammals continue to form head and neck structures Thanks to this structure, fish form their gills.

Therefore, there are theories circulating that fish gills are evolutionary evidence, but… It has not yet been scientifically tested. However, if we consider that our coccyx, feathers, and appendix are inherited from our evolutionary ancestors, it doesn’t seem impossible.
