Stahl’s Ear is known by a number of other names. It’s been called Satiro’s ear, Vulcan or Spock ear, and elf ear. It’s a development of an extra cartilage fold in the ear, which gives it a natural pointed shape.
Thankfully, the extra fold and different shape haven’t presented any other changes – not even with hearing. However, many parents still chose to have the ear reshaped in order to, perhaps, reduce possible future teasing. This can be done with a simple mold if it presents young enough, or an outpatient procedure if the child is older. If they don’t get it corrected, the kid will save tons on costume supplies.
Walking on All Fours
It's possible that only one family in the entire world suffers from this peculiar disorder. Uner Tan syndrome is named after the evolutionary biologist who first studied it, finding it in a single-family in rural Turkey.
The condition is, even by neurological conditions, quite strange. Individuals who suffer from it walk like quadrupeds – on all fours. They also use primitive speech and have a congenital brain impairment, which includes something called “disturbed conscious experience.” Tan believes that the condition is due to some sort of backward stage of human evolution, but other experts aren't convinced that genetics has everything to do with it.
Hey, No Clipping Needed
Anonychia congenita is a rare disorder that takes place during formation, in which a person's toes or fingers don't develop nails at the end. It's such a small change, but just imagine having toes or fingers that don't have nails. You'll feel so strange.
It doesn't seem too bad all things considered, and as far as we can tell it doesn't come with any other effects. It could be due to a number of things, including infection, trauma, skin diseases, and even plain old genetics. Not only can people have no nail, but they can also have just part of a nail.
An Eyeball Scar
A corneal scar happens when the cornea of your eye, typically transparent and clear, has an opacity or irregularity that blocks light. Not all scars affect vision, but many of them can mean a significant loss of vision.
These scars can develop because of injury or trauma, infections, or eye diseases, and have numerous effects like pain, swelling, and the constant feeling that something is in your eye. Which sounds like torture. Corneal scars may not change over time, or they may worsen due to an underlying disease. Milder scars may only require glasses to correct the vision, but more serious scars have a number of treatments available to mitigate or remove the damage.
They Get a Slight Advantage While Swimming
This is one of the more common traits on this list – it's likely someone you know has this feature, as it develops in one in two thousand live births. Webbed toes present most commonly as a connection between the second and third toes, with skin that extends higher. It can sometimes reach all the way to the end.
The specific cause of this condition is still a mystery. There is clearly some genetic component, as close family members can share the trait, but there are a number of possible reasons. If you have this condition, don't feel bad – Ashton Kutcher also has it.
