Why do people have five fingers on their hands and feet? Why 5?

Why does each of us have no more and no less ten fingers and ten toes? British researchers have done a study of mice with lesions in their limbs, revealing why humans have five fingers on each hand instead of six or seven. They found that five is already the limit.

British researchers in rats found that if an animal has more than five fingers, their palms or soles are forced to arc to accommodate the extra fingers or toes, and the tops of the extra fingers are also distorted, thus affecting the animal's dexterity and their gait, so that they cannot walk or run well, and this change further affects the animal's ability to hunt and escape, affecting their ability to survive. Chris Hayes of a neuroscience research centre in Essex, England, who led the study, points out that this also explains why animals have evolved along the path of five fingers per limb.

Researchers have found that animals with more than five toes can't get their feet flat on the ground. Instead, they had to find ways to adapt their feet to the bent leg bones. They're even walking on their ankles!

In their experiment, a mouse with ten toes on each foot was severely affected and found that the mouse's dexterity was so severe that it was almost impossible for it to survive.

It's better to count every five and ten.

It is convenient to count when you are a child

The thumb is the head of the finger, so it represents a deep meaning, generally representing parents and ancestors.

The index finger is in palmistry.

Medium, usually means the desire for dominance, the desire for power and a person's enterprising, a person's career will not have achievements can be seen, so the person with a longer index finger, the character is also more tenacious, as long as it is the thing that they believe ten cows can not pull back, will set a goal for themselves first, ignore others to ridicule their unreality, step by step slowly approach their goal, this kind of person can basically achieve great things, quite domineering and ambitious, easy to have power, and also ambitious, More than what you get in front of you, always thinking about trying to climb up, many people may say that this kind of person is to achieve the end of the means, but now this society needs this kind of person, only this kind of person can succeed quickly.

The middle finger is the longest of the four fingers, and is located in the center of the five fingers, symbolizing a person's fate, this finger can best represent the recognition of character traits, if the round and straight length is the top, the round and straight middle finger, on behalf of a good fate, career, wealth, marriage have good results, this kind of person may not be very rich, but it can also be said that there is no need to worry about food and clothing, a stable job and a dull family, there are not so many vigorous things.

Zhou Yinhe text.

Human fingers and toes are generally five, but there are a few people who are six, commonly known as six fingers, six pestles, and so on. In addition to being related to yin house feng shui, genus physiognomy, ranking, etc., this phenomenon also has a certain performance in the eight-character numerology.

The "finger" of the finger, the ancient dictionary explains that it is "branch", which is the shape and sound of the word, and is the top of the branch of the tree, which is wood from the five elements; In the gossip, the finger is in the Gen Palace, which is the Yinmu of the Gen Mountain. If you understand the eight trigrams of the fingers, you will have a good understanding of the phenomenon of the six fingers. The six fingers are in addition to the normal five fingers, and the extra finger is the repetition of the fingers.

The sixth finger we often see is smaller and shorter than other fingers, and there is a sign of disability, which shows that Yinmu is not only groaning, but also cut off by Jinke such as Si, You, and Shen. From the "dagger" on the right side of the finger "finger", we can see that the "dagger" has the image of "巳", which refers to the weapon Gengjin that has been forged with fire in the middle of the finger. Therefore, the person with six fingers in the eight characters, whether it is fingers or toes, is the person who is in the middle of the pillar and has been burned at the stake. If there is no Yinmu in the column, but there is one Shenjin, two fires, or one fire and two Shenjin, it is easy to have six fingers, the principle is that the Jin Taiwang in the pillar groans, and secretly hurts the Yinmu part of the body (although there is no Yinmu in the column, but the Lord must have fingers, and the fingers will be secretly injured by the Si and Shenjin in the column), in other words, it is the Jin Taiwang of the injured wood in the column, and the fingers will grow out from the side of the palm or the side of the fingers when they are conquered.

We also often see the sixth finger either growing from the side of the palm or from the side of the finger.

Some people are rich and prosperous in the eight characters, but they don't see that the fingers are six fingers, which is related to their feng shui, Dayun Yin and weak wood, once they help Wangmu, the wood is Wangjin's gram, but the fingers will be disabled.

Thumb, index finger, middle finger, ring finger, little finger.

1. Thumb: Also known as thumb, big finger, giant finger, thumb, the thickest one, so it is called thumb.

2. Index finger: also known as index finger, human finger, salt finger, head finger, when there are no chopsticks, they use this finger to dig something to eat or taste the taste of the food first, so it is called the index finger.

3. Middle finger: also known as long finger and finger, because it is located in the palm of the hand, it is called the middle finger.

4. Ring finger (third finger &ring finger): medically known as medicine finger and ring finger, it is a finger used to wear a ring, and after marriage, it will turn a person from a nameless to a famous person, so it is called a ring finger.

5. Little finger: also known as quarter finger, little finger, tail finger, little finger, located at the tip of the tiniest finger at the tail end, so it is called the tail finger.

It is because human beings have evolved into the most suitable form for human life when they have adapted to the living environment for a long time, the five fingers are very suitable for our life, the thumb can be in contact with any other 4 fingers, and any two of the 5 fingers can also be touched to varying degrees, such a structure is more conducive to our work and study form.

Perhaps you have wondered why we humans have 5 fingers per hand and 5 toes per foot, instead of 6 or 7? In order to figure out the question that each of our hands (feet) is no more or less 5 fingers (toes), British scientists claim to have found the answer through a special study of mice with extra toes. They point out that in fact, 5 is already the limit.

Their explanation is that if an animal has more than five toes, the bones of other parts of its limbs will be deformed, causing it to be unable to walk or run normally, seriously affecting its ability to hunt and escape predators.

At the Mouse Chromosome Research Centre of the Harvey Medical Research Council in Oxfordshire, England, scientists working on abnormal mice found that if animals have more than 5 fingers, their palms or soles will be forced to grow into arcs to accommodate these extra fingers or toes, and the top of the extra fingers will also be twisted and deformed, which affects the flexibility of animals and their gait, so that they cannot walk or run well, and this change further affects the animal's ability to hunt and escape. The point is that it affects their survivability. Chris Hayes, who led the study, pointed out that this also explains why animals have evolved along the path of five fingers per limb.

Scientists have found that the extra toes of the rats will compress their limb bones, forcing them to grow in an arch shape rather than a straight line, so those animals with more than 5 toes can not make their feet flat on the ground at all, because the curved leg bones can only be at an angle to the ground, barely coping with walking. They're even walking on their ankles! Scientists have also found that the more toes an animal has, the less flexible it is.

In their experiment, a mouse with one toe on each foot was severely limited in its flexibility, and it was almost impossible to survive. Scientists have also studied a type of mouse with a genetic defect that has more toes. The addition of the extra tibia causes the bones of his limbs to roll up and grow.

However, animals are comfortable with missing one or two toes. Chris Hayes argues that hoofed animals such as horses have evolved to walk with only one hoofed toe, suggesting that even if the number of toes decreases, the animal's forward evolution will not be affected. He also believes that if this anomaly is objectively normal, then animals with extra toes should be prevalent in nature.

For example, the giant panda, a rare animal today, has five toes on each paw and an extra meat toe on its wrist, which is used to stabilize the branches and leaves of bamboo when it eats, but there are not many pandas surviving today. It is also common for humans to have extra fingers, but it does not affect their survival.

Because 5 fingers are the best combination to support crawling ability and swimming ability, too few of them will weaken the paddling ability, and more than 5 will have too complex structures and weak crawling ability. The birth of the five-fingered forelimb can be traced back to ancient times, but its influence continues to this day. Today's development in mathematics, literature, aesthetics, engineering, and many other aspects is inseparable from this five-fingered forelimb.

Human beings can be defined in terms of biology, spirituality, and culture, or a combination of these definitions. The definition of human beings in ancient China is: an animal that has historical classics and can use historical classics as a mirror for self-reflection.

Biologically, humans are classified as hominoids, chromosome 2 and orangutan nail chromosome centromere fusion (equilibrium translocation) association mode proximity of more than 16n, and multiple interarm inversions, the rest of the chromosomes have strong homology, is a higher animal.

In cultural anthropology, human beings are defined as beings who are capable of using language, have complex social organizations and technological developments, and are especially capable of building groups and institutions to support and assist each other.

The five fingers are called the thumb, index finger, middle finger, ring finger, and little finger. The thumb, also known as the thumb, big finger, giant finger, and thumb, is the thickest of the five fingers, so it is called the thumb. The index finger is also known as the index finger, human finger, salt finger, and head finger, and when there are no chopsticks, they use this finger to dig something to eat or taste the taste of the food first, so it is called the index finger.

Middle finger: also known as long finger and finger, because it is located in the palm of the hand, it is called the middle finger.

Ring finger: medically known as medicine finger, ring finger, is a finger used to wear a ring, after marriage will turn a person from a nameless to a name, so it is called a ring finger.

Little finger: also known as the quarter finger, little finger, tail finger, little finger, located at the tip of the tiniest finger, so it is called the tail finger.

The story of the fingers

One day, five fingers got together to discuss who had the most skills.

Thumb stood up first and said proudly: "This question is very simple, of course my skills are the greatest, otherwise why am I in the first place?" The index finger was gone, and he hurriedly said:

I'm the most amazing, no matter what people do, they use me to point fingers, where are you guys? ”

The middle finger didn't wait for the second thumb to finish, and quickly stood up and said, "Look and see, straighten out five fingers, and compare who is the tallest." ”…Not to be outdone, the ring finger and little finger all showed their housekeeping skills and argued with them.

Their quarrel was heard by the flower ball in the corner, and the flower ball gave them a suggestion: whoever can handle it will be the most meritorious. The five fingers looked at each other, and they all thought that the suggestion was feasible, so they tried one by one, but none of them could pick it up.

Hua Pi Ball made another suggestion: What if you could pick it up with five fingers together? Five fingers went into battle together, and sure enough, they picked it up with a light hand.

Five fingers, you look at me, I look at you, and they all laugh embarrassedly. They finally understood that "unity is strength".
