Do You Have This Small Hole Above Your Ear? Here’s The Reason (Watch Video)

A very small fraction of people are born with a tiny hole above their ear, and here’s why. This hereditary birth defect goes by the name preauricular sinus. It was first documented in 1864 by doctor Van Heusinger. Not much information has emerged about the defect until evolutionary biologist and fish paleontologist Neil Shubin shared his idea. Shubin thinks that the hole could be an evolutionary remnant of fish gills, viralthread.com reports.

In his PBS show, Your Inner Fish, Shubin talks about other things that our water-dwelling ancestors gave us. “Now you might not think your body has a lot in common with a fish,” he said. “But I see a family resemblance.”

Fish are not only the first creatures with bony skeletons including backbones and skulls, they’re also the first animals on earth. The timeline of species goes fish, amphibians, reptiles, mammals, which then developed into us – primates. Believe it or not, every animal on earth today is a descendant of an ancient fish. Even the nerves in the human head are the same as the basic wiring inside a fish.

You may think it’s far fetched to think people carry a trait so similar to fish, but it’s not. After all, there are some people who have webbed toes. Thankfully, Shubin has more mind altering information on his show. So you may not be able to breathe underwater, but a very distant relative of yours could.

Between 0.1 per cent and 0.9 per cent of the US and European population deal with this defect. But 2.5 per cent of Taiwanese and 10 per cent of people in some parts of Africa are found with this as well. The holes can appear either on one or both sides, but it’s mostly found on the right ear.
