There are no identical people in the world, and there are a variety of characteristics that will distinguish us from others.
But for some people, their characteristics are very scarce, and they can be called "chosen children"!
Next, let's take a look at these rare human characteristics, how many can you have?
The source of this article comes from the official media (Sina.com's "Rare Physical Features: 10 Rare Features Only a Few People Have", China Digital Science and Technology Museum's "Mirror Man: The Human Body Also Has a "Wrong Version"", The Paper's "Internal Organs Are Opposite" Mirror Man, Just Like a Replicant from the World in the Mirror"), but in order to improve the readability of the article, the details may be polished, please read sensibly, for reference only!
Severed
Broken palm, the more rigorous name is "single horizontal palm crease". Human palm prints are usually composed of multiple palm prints, and like fingerprints, they cannot theoretically run through a straight line. But if it's your severed palm, it's a different story.
When a person spreads out the palm of the hand, and a line appears in the center of the palm that runs through the palm, then he is a part of the broken palm. Globally, about 1.5% of people have their hands broken, and men are twice as likely to have their hands broken as women.
Severed palms are generally hereditary, and the older generation on the mainland always regard them as a bad omen, but folk fortune tellers are quite interested in it. In order to make it easier to see the face, they divided the severed palm into a lifeline, a career line and an emotional line, as if there was really such a thing.
Whether the severed palm is good or bad for people is still inconclusive. It's really just a trait, and it's a bit outrageous to think of it as the key to determining fate. After all, "my life is up to me, not to the sky", people still have to rely on themselves to turn the tables against the wind!
Bend your thumb
Crooked thumbs, also known as "hitchhiking fingers", is something that about 32% of people worldwide can do. Tighten your thumb first, then lean back, and be able to bend at an angle to prove that you are bending your thumb.
This process sounds simple, but it's not really easy. Most people's thumb muscles lack flexibility, and even if the muscles are only slightly tightened, the thumb will still feel pulled.
According to research, the crooked thumb is a product of human evolution and does not have adverse effects on its own. However, this feature, while rare, has little practical use. If you have to say it, maybe to make people feel more special?
dimples
Dimples, also known as "laughing dimples" or "pear whirlpools", can be described as a "plus" to a person's appearance, making people laugh smartly and cutely. Dimples are usually inherited from parents or immediate family members, with some people having dimples on one cheek and others having dimples on both sides.
Dimples are 25% more likely to occur, and the sides of the cheeks automatically sink when people with this characteristic perform facial activities. This occurs because the person has defects in the facial muscles. However, with the development of medical aesthetic technology, people can now obtain dimples through surgery, and it can no longer be regarded as a rare human feature.
Pleated tongue
From a biological point of view, the human tongue is mainly divided into flat tongue and rolled tongue, so what does the pleated tongue look like? The pleated tongue is also known as the "lotus tongue", people with this kind of characteristics can usually curl the tongue into the shape of a lotus, and they account for only 1/200,000 in the world.
Independent ring finger
Try doing this by bringing the palms of both hands together, followed by bending the two middle fingers back into the palms. It doesn't look like a hard thing, but can you really do it? Actually, because of the tightness of the thumb, index finger, and little finger, most people can't keep the ring finger separate.
Fingers and fingers are like conjoined babies, no one can do without each other, and the same is true for the middle and ring fingers. However, according to statistics, there are still 2% of people in the world who can easily control the ring finger to work independently with flexible finger tendons.
Move your ears
When it comes to "moving ears", everyone's first reaction is the "ear-moving magic skill" in the cartoon "Big Ears Tutu", so does this skill really exist in reality? According to statistics, although there are people who can move their ears in the world, the proportion is not many. For example, 22% of people can move one ear, and even fewer people can move both ears at the same time, only 18%.
A similar example is the foot, where some people's toes can also move individually to complete movements such as swinging and shaking. Studies have shown that people with this trait generally have a well-developed cerebellum and are more gifted than others in sports.
Mirror person
The biggest difference between mirror images and normal people is that their thoracic and abdominal organs are not "seated", but completely misaligned. For example, the liver and gallbladder and appendix are on the left side, the spleen and pancreas are on the right side, or the left and right lungs are reversed. However, despite the deviation in the position of the mirrored person's organs, it is generally not life-threatening.
In the spring of 2018, Oregon Health & Science University dissected a 99-year-old woman named Rose, who had a left-right misalignment of her liver and abdominal organs, and the direction of the blood vessels around her heart was different from normal. But Rose's heart was not defective due to organ reversal, and even though she had undergone multiple surgeries in the middle, her body did not suffer from any diseases other than arthritis.
However, although this developmental malformation does not affect the normal life of the person, it is not without harm to mirror the person. According to statistics, patients with retrograde left internal viscera have a 95% chance of congenital heart disease and are prone to heart problems. Try to think about it, if a mirror person goes to the doctor, their organ reversal will also cause a headache for the doctor, causing a certain interference in the diagnosis of the condition.
