Why some people have this tiny mark above their ear

If you have this tiny mark above your ears – listen up.

Preauricular Sinus
A small percentage of people are born with tiny holes above their ears. In technical terms, this is called a preauricular sinus.
The rarity of this sinus depends on where you live, but in some parts of Africa and Asia, around 4-10% of people are thought to have them.
And now scientists have revealed that any nodules, dents or dimples around the external ear – where the face and cartilage meet – could be an remnant of our evolutionary past.

Evolutionary Biologist, Neil Shubin, thinks the holes could be the remnants of fish gills.
And while they are nothing to worry about – these little quirks could be an interesting insight into our past, before we were human.
