15 Unusual Body Features That Occur Very Rarely

body

The human body is amazing. It has been the inspiration of countless of artists for millennia. It has been studied by scientists for just as long, and they still haven’t uncovered all of its secrets – just a few months ago, a new organ was discovered. The human body is such a complex system with incredible capabilities. Just think of the way the organs shift during pregnancy, or how whenever something breaks down, it can be healed.

But some people’s bodies have unique attributes which make them more special than others. No, it’s not superpowers, unfortunately. It’s just little things, details that probably you won’t even notice, but, nonetheless, these characteristics set some people apart and make them remarkable.

Check out this list, compiled by Auntyacid, of 15 uncommon features your body may have.

1. Wisdom teeth

body

Some people know the pain of having to extract their wisdom teeth. But 20% of the human population are born, very luckily, without third molars! This percentage varies in different ethnic groups. For example, all Tasmanian aborigines have wisdom teeth, and almost 100% of the population of Mexico is born without them! Fascinating!

2. Blue eyes

body

It is estimated that, of all the people in the world, only about 8% have blue eyes. They are most common in the northern European countries like Estonia or Finland. The reason for this eye colour lies in the mutation of the gene HERC2. The first time this mutation appeared was probably when humans migrated from Africa to Europe 6,000-10,000 years ago. That is why only people with European descent can have blue eyes, which means that all the blue eyed people in the world share a common ancestor!

3. Morton’s toe

body

If your first toe is shorter than the second, then you belong to the 10% of people who have Morton’s toe. In the past this body feature has been associated with beauty, and supposedly Cleopatra’s toes were like this as well. Throughout the centuries, many artists and sculptors have given their creations Morton’s toes; even the Statue of Liberty has feet like this.

4. Hair whorl

body

Counterclockwise hair whorls are present only in 8.4% of the human population. The percentage is significantly higher in left-handed people. 45% of lefties have this unusual hair pattern.

5. Sneezing

body

Some people are allergic to the sun. Yup, being exposed to sunlight causes sneezing in 25% of people. Known as the “photic sneeze reflex,” people with this condition sneeze when they look at a bright light like the sun. In the United States of America, 18-35% of the population are affected by it. Scientists still haven’t discovered the exact mechanism of the action.

6. Single palmar crease

body

If you have the single transverse palmar crease, also called the “simian crease,” then your palms, instead of two creases, have got only one. This is twice as common in men as it is in women, and seems to be a hereditary trait. The populations with the highest percentage of single palmar creases are the Asians and the Native Americans, and they are more likely to have it on only one hand.

7. Outie navel

body

The outie navel, or inverted bellybutton is present in 10% of adult humans. Contrary to popular belief, it’s not the way the cord is cut that determines the shape of the navel, but the way the scar heals afterwards.

8. Heart on the right

body

It is estimated that less than one percent of all the people have their heart on the right side of the chest instead of the left. This hereditary condition is called dextrocardia and usually has no negative impact on the health. Also, if you have dextrocardia, probably many of your other organs are located on the opposite side of your body as well.

9. Clasping hands

When you clasp your hands, what position do your thumbs end up in? 50% of people place the right thumb above the left, and 49% have the left one on top. The remaining one percent places the thumbs side by side. Weird!

10. Fingerprints

body

Arch-shaped fingerprints are present in only 5% of the population. The rest of us have simple loop-shaped or whorl-shaped fingerprins.

11. Light hair

body

Hair usually darkens with age, which means it’s a pretty rare occurence to find an adult with natural blond hair. Different countries have varying percentages of natural blonds: they can range from 2-16%.

12. Red hair

body

Blonde hair is rare, but red is much rarer. This hair colour is the consequence of a genetic mutation present in only 1-2% of the world’s population and scientists believe that it is dying out.

13. Curly hair

body

Curly hair is fairly common, right? Wrong. Only 11% of all the people has naturally curly hair.

14. Х on hands

body

Having the lines on the palms of both of your hands form the letter X is a very rare occurence. In fact, only 3% of people are said to have this trait, and it is even considered to signify strength of character.

15. Gleeking
body

Ever heard of gleeking? It’s when you spit saliva from the gland below your tongue. It’s present in 35% of the population and it happens spontaneously, so you could gleek while talking, eating, or yawning. That’s not weird though. The weird thing is that less than 1% of people can actually gleek on command! Eek!
