What are the imperfections in the structure of the human body?

For example, the pelvis, spine, stomach and other parts of the human body. These areas are not particularly perfect and are prone to glitching.

Among the imperfections in the human body structure are: the trachea and esophagus share an opening, lumbar spine problems after walking upright, the pelvis is too small, the head is too large and prone to dystocia, and the eyes have blind spots and almost no night vision.

What are the imperfections in the structure of the human body? 500 million years ago,—— hunter - hunter appeared a bunch of shining light. It was the morning sun.

After being born under the sun, hundreds of planets and various small corners have appeared to form the early solar system. After 400 million years, an extraordinary planet was born, which is the earth we live on. Early Earth was also a world of purgatory, with a burning lava everywhere.

After successive evolutions, the earth cools down, forming stable and beautiful ecosystems. 38 billion years ago, the earliest primitive life on Earth was born in the ocean. After a long evolution, intelligent humans were finally born millions of years ago.

The birth of human beings has made the earth a planet of intelligent life, and human beings are the first intelligent civilization we know.

Life can be imaged from a very primitive and simple structure to the same advanced intelligent life, which is absolutely a miracle of life and a miracle of the universe. Humanity stands on the pyramid of life and rules the earth. He entered the technological age hundreds of years ago and began to explore the universe.

Is it so sophisticated and advanced, perfect? In some people, humans are high-grade intelligent beings, and the body structure is inevitably and perfect. The other animals are ours.

But through continuous research, scientists have found that human structure is not perfect, and there are many irrationalities. So, what is the irrational position in the human structure? We just analyze from head to toe.

The top of the human body is the core structure of the human body and is the most important part of the human body. The reason why human beings are an intelligent person is because the existence of the brain is the brain, and the brain is the center of the entire human system, the headquarters. For such an important one, in the course of natural evolution, humans naturally evolved a lot of powerful defenses.

For example, our head has a very rigid cannula with many layers underneath the shell that protect our brain. However, it must be kept secret. This important head also has a weak position of the body, which is the temple on either side of the forehead.

The temporal position is along the intersection of ethylenediamine, butterfly, temporal bone, with a thickness of 2 mm. It is very thin, with an average thickness of more than 6mm, and 2mm is a layer of paper that is enough to protect the structure of the brain. Some people may say that maybe there are no important things in the temple and in the back, so it's too thin.

In fact, there is a type of intravenous vein, including intravenous veins, intravenous veins, varicose veins, and eyelashes and ciliary body deities. In this thin skull, which is the center of the brain, it carries human vision, hearing, language, and memory, and is a very important location of the brain.

The eyes do not have night vision, and there are many blind spots, the bones of the lumbar spine are many problems, and the size of the pelvis is not very suitable.

The trachea and esophagus share an opening.

This may be one of the most criticized defects, which can lead to a very serious problem, that is, accidentally choking on the trachea while eating, and then causing suffocation and death! Maybe it's because humans have evolved to prevent themselves from suffocating themselves when they have a cold and nasal congestion, so they have opened a channel from the larynx to the mouth, or maybe it's also an extra intake and exhaust channel during strenuous exercise, like a turbocharger!

Who is who, life can evolve from the most primitive and simple structure to the advanced vital signs of human beings, in fact, it is a miracle in life and a miracle in the world, human beings are also standing at the top of the pyramid of life, we occupy the earth, and also let some science and technology appear, and at the same time into the era of science and technology, but also began to explore the mystery of the universe. Human beings are very complex and advanced living beings, but is the structure of the human body perfect? Are there any flaws?

Let's talk about it. <>

Human beings are advanced intelligent life forms, and the physical results must be very perfect, other animals are of course incomparable with our body structure, but after continuous research by scientists, it is found that the body structure of the human body is not perfect, because there are many places that are also unreasonable, so what are they? Because the top of the human body structure is actually the core structure of human beings, the head is a very high-end structure, for human beings is the existence of intelligent life, so the existence of the head has a brain is very important, and now the head also has a great defensive role in human evolution, the head has a lot of hard shells, which can play a role in protection, but the human head is also the weakest position, that is, the temples on both sides of the forehead, the thickness of the temples is actually very thin, and it is also a layer of paper like a poke to break. <>

Therefore, the position of the temple is very important, once it hits, it is easy to cause a person to collapse, it may be seriously injured, and it may kill people, so the protection ability of such an important place is very poor, so human beings are actually very unreasonable on the road of evolution. <>

The eye is also defective, because the eye is an important structure in the head, and it is also an important structure in our human body, but the function of the human eye is not very strong, in general, many people will wear myopia glasses, because there are very few people who have reached the standard vision, which shows that the human eyesight is not good, and the function is relatively fragile, but some animals have very strong eyes, but if there is no light at night, under the guidance of the light, it is completely blind, I can't see anything clearly.

The human body is not reasonable.

Walking upright is an important differentiator of humans from other primates, but walking upright is not without its drawbacks. If you compare the bones of chimpanzees, you will see that the pelvis of chimpanzees is much wider than that of humans, and a wider pelvis leaves enough space for the birth canal to make it easier for women to have offspring.

The pelvis of humans is very narrow compared to that of chimpanzees, and this is because they need to walk upright, otherwise too wide the hip bones will cause humans to walk like chimpanzees.

A too narrow pelvis is a disaster for women, because a too narrow pelvis can squeeze the woman's birth canal, making it narrow and rugged, and our baby needs to adjust the head direction twice before it can be born.

If the narrowness of the birth canal has caused human women to suffer from childbirth, then the enlarged brain of human beings has led to maternal and infant mortality.

We know that after walking upright, humans began to try to feed on meat, which contains a lot of energy. Coupled with the fact that digestion of meat does not require a longer intestine, the human intestine can evolve to be shorter, the intestine is a high-energy organ and a shorter intestine means more energy saving. Also, walking upright is a very energy-efficient way of walking, which helps humans save some of their energy.

In such an environment, human beings have excess energy for the development of brain capacity, so the human brain capacity gradually expands.

First: the head is too big, and the mother is in danger of dystocia when reproducing a new generation. Second:

The spine is subjected to too much pressure and is prone to lesions. Thirdly, the position of the photoreceptor cells and ganglion cells of the eye is reversed, resulting in the light passing through many layers of cells to reach the photoreceptor cells, and the visual quality is reduced.

The uppermost part of the human body structure is the core structure of the human body, the head, which is the most important and high-end structure of the human body, and the reason why human beings are intelligent life is because the head has a brain, which is the center of the entire human body system and the headquarters. For such an important head, human beings have naturally evolved many powerful defenses in the process of natural evolution, such as our head has a very hard shell, and there are multiple layers of protection under the shell to protect our brain. But there must be a mistake in the hundreds.

Such an important head also has one of the weakest points of the body, which is the temples located on both sides of the forehead.

We know that the human organism is almost perfect, and even a small cell has a life path that is far more complex than all the electrical devices in the world. However, we only know a little about the entire operation process of cells, and we still need to discover more life mechanisms. From microscopic apoptosis to autophagy, from the birth of macroscopic life to death, every process is like a carefully choreographed.

Could it be that nature really has such a great ability to design? So some people wonder if we humans were "designed" by some kind of intelligence.

From the origin of species on the earth to the emergence of human beings, the earth has changed countless batches of species and has countless possibilities, but why only human beings stand out (although many people fantasize that there may have been prehistoric civilizations before the emergence of human beings)? What will the future hold for humanity? It's all a litany of mysteries.

The earliest ancestors of mankind

Compared with animals, many people think that we humans are born suddenly, thinking that the appearance of human beings is only 1 million years, in fact, there were billions of years of biological evolution before humans, and it was only by chance that 65 million years ago that the extinction of dinosaurs led to the development and growth of mammals! The earliest ancestor of mankind, the ape, began to stand up 35 million years after the extinction of the dinosaurs!

Human beings are not designed to be

If human beings are subjected, then from these tens of millions of years of development, super civilizations will have countless opportunities to correct human genes, so why do we still have so many defects? For example, our eyes have a large number of blind spots, and even blind spots! In addition, our respiratory tract shares the same esophagus, and how many people have died from this defect!

Most importantly, there are a variety of defects in our genes, and the resulting diseases can be avoided by modifying them.

Everything in the universe operates under the control of physical laws, and there is no need for designers and controllers, and the only thing human beings can do is to use these laws to survive better. Human beings have already begun to prepare to be a designer, and they are not qualified yet, and they will definitely be able to erase their imperfections in the future.

Scientists have discovered that the structure of our human cells is complex and rational, just like a computer program. We humans come from ** and will eventually go**, and our current traditional concept is a frog at the bottom of a well.

It is impossible to be sure, and the only thing that can be determined now is that the abilities possessed by human beings, including their appearance, have evolved over tens of thousands of years.

Actually, no, the human body is actually the result of natural evolution.

It is highly probable, because it would be difficult to form such a wonderful structure if it were formed naturally.

It's just the result of natural evolution, which is bound to pick out better structures.

This is the result of adaptation to the evolution of the environment, which has been selected through evolution from generation to generation.

Probably not, because this is most likely the result of natural selection.

It's really not, otherwise who designed it, who is so powerful.

It's not impossible for this thing to be, after all, who knows what this thing is.

There are many universities when issuing admission notices, not only will there be a notice, but also a note for admission, and will bring a bank card by the way, and many people do not understand what the use of such a bank card is, in fact, this bank card is the general bank card of the school, usually students pay the tuition fee by depositing the money into the bank card, and then the school will transfer the tuition fee from the student bank cardHowever, it does not mean that everyone must use this bank card to pay for tuition, but it is very useful in many cases, including if you get a scholarship because of your excellent grades in school, the school will also transfer the scholarship to this card, and then let the students withdraw it by themselves.

Or if the family conditions of some students are not very good, you can apply for a loan from the local place of origin, at this time you need to provide a bank card, because the loan applied for from the country is to be sent to the bank card designated by the school, that is, the bank card issued by the school, it must be protected at ordinary times, do not litter at will, if it is not used in ordinary times, you can also use this card as a storage card, and put the money you have saved into it, which is also a good method. It's like getting a memory card for nothing.

At the same time, some school bank cards and meal cards are also bound, if there is no balance in the meal card, you can also recharge directly on the school machine, which is very simple. If there is a bursary, as well as the issuance of scholarships, or the purchase of medical insurance during the university, the balance will be directly hit to this card when the medical insurance is reimbursed, so in normal times, students must keep this card, otherwise many of them can not be found when they are in urgent use, and it will become very troublesome if they are lost, and this bank card is handled by the school in a unified manner, and there is also the information of each student in the school's client, when remitting to Ruxin scholarship or grantThere will be very clear information, and students do not need to bring their own bank cards.

If students do not apply for loans, there are no grants and scholarships, do not feel that this bank card is a waste card, it can also be used as a memory card in ordinary times, so that you can get a memory card for free without processing, and this memory card is exempt from annual fees. It is also very convenient to store all the pocket money you can save in this card.
