Five billion years ago, on the third spiral arm at the edge of the Milky Way, the Orion spiral arm, a shining light appeared. It was the early sun. After the birth of the sun, hundreds of planets and various small celestial bodies continued to appear, forming the early solar system.
After another 400 million years, an extraordinary planet was born, and it is the earth on which we live. The early earth was also a world of purgatory, with burning lava everywhere. After continuous evolution, the earth cooled down and formed a stable and beautiful ecosystem.
3.8 billion years ago, the earliest primitive life on earth was born in the ocean. After a long period of evolution, life finally gave birth to intelligent life mankind millions of years ago. The birth of mankind made the earth a planet of intelligent life, and mankind is also the first intelligent civilization as we know it.
Life can evolve from a very primitive and simple structure into an advanced intelligent life body like human beings. This is definitely a miracle of life and a miracle of the universe. Human beings stand at the top of the pyramid of life, dominate the earth, and entered the age of technology hundreds of years ago, stepped out of the earth and began to explore the universe.
Is such a complex and advanced human being perfect? In the eyes of some people, human beings are high-level intelligent life forms, and their body structure must also be very reasonable and perfect, and other animals are completely incomparable to us. However, scientists have discovered through continuous research that the human body structure is actually not perfect, and there are still many unreasonable places. So, what are the unreasonable places in the structure of the human body? Let’s conduct a simple analysis from head to toe.
The uppermost part of the human body structure is the human core structure, the head. This is the most important and highest structure of the human body. The reason why human beings are intelligent lives is because the head has the brain. It is the center of the entire human system and is the commander. unit.
For such an important head, humans have naturally evolved many powerful defenses in the process of natural evolution. For example, our head has a very hard shell, and there are multiple layers of protection under the shell to protect our brains. . But one hundred secrets must have a sparseness. Such an important head also has the weakest part of the body, which is the temples located on both sides of the forehead.
The temple is located at the intersection of the parietal bone, sphenoid bone, temporal bone, and frontal bone. The thickness is 2 mm, which is very thin compared to the average 6 mm or more of the forehead skull. 2 mm is a layer of window paper for protecting the brain structure, which breaks with a poke.
Someone might say, maybe there is nothing important around and behind the temples, so it’s so thin. But in fact, there are abundant arteries and veins in the temple area, including the middle meningeal artery, middle meningeal vein, and the intersection of the trigeminal nerve and the ciliary ganglion. And in this thin layer of skull, it is the central brain temporal Ye, it controls the human body’s vision, hearing, language and memory, and is a very important position in the brain.
It can be seen that the position of the temple is very important. If it is hit, it can easily lead to a person’s collapse, ranging from serious injuries to serious injuries. But in such an important position, the protective ability is very weak. I have to say that this is a very unreasonable place on the evolutionary path of the human body.
In the female pelvic cavity, the reproduction of offspring is the most important responsibility and obligation of life, and it is also the key to the continued prosperity of life. Human beings want to continue to prosper, and this is naturally inseparable. If a friend has raised cattle, sheep and other animals, you will find that these mammals are very easy to give birth to children, and dystocia rarely occurs.
And there is no difference between animals before and after childbirth, and there is no need for confinement like humans. The reason for this huge gap is that the female pelvis is relatively small. We all know that the ancient apes, the ancient ancestors of mankind, learned to walk upright after embarking on the path of evolution.
Walking upright is an important sign that humans are embarking on the path of intelligent evolution, and walking upright does have many benefits for survival and evolution. However, walking upright will also bring some burden to the internal structure of the human body. The smaller pelvic cavity is one of the places that has a greater impact. Compared with mammals, the pelvic cavity of humans is pitifully small, resulting in a small birth canal, so the baby will not be born smoothly, and dystocia often occurs.
Even if the child is born successfully, women need to rest for a long time before they can recover, which is what we know as confinement. Fortunately, after humans have entered the age of technology, with the help of science and technology, advanced medical technology can assist production, and even cesarean section can ensure the safety of mother and child.
The heart has a heavy burden. The heart is also a very important structure of the human body. It is like an engine. The flow of blood and energy in the human body needs it to complete. But walking upright also puts a huge burden on the heart. The brain is the most energy-consuming structure, which consumes 20% of the body’s energy every day.
The transfer of these energy needs the heart to complete, and the blood in the legs to return to the heart, it also needs the power of the heart to complete. Once the heart’s power is insufficient, the human body will have various problems, so we will see that in various human diseases, the probability of heart disease is much higher. Heart disease is rarely found in animals, especially chimpanzees, which have a common ancestor with humans, who rarely get heart disease.
The small intestine is very inconvenient for humans. Although humans are omnivorous, except for a few vegetarians, most humans are carnivores. And there are almost no absolute vegetarians. After abandoning faith, vegetarians will soon become fanatic carnivores.
Therefore, eating meat is the main theme of human daily life. Compared with vegetarian food, meat naturally needs more powerful digestion ability. The digestive ability of the human body is actually incomparable with many animals. Generally speaking, the digestive ability of the human body is actually not strong, so we only need to eat cooked food. Even so, the human body’s intestines and stomach often have problems. The reason for this is that the human body has a long small intestine.
In our opinion, the structure of the small intestine is completely a structure that vegetarians should have, but it appears in humans, which are enthusiastic about carnivorous organisms, and is completely unmatched. Therefore, for our health, vegetarian and fibrous foods should occupy a certain proportion, and meat should not be eaten purely, otherwise the stomach and intestines will protest and cause various gastrointestinal diseases.
Eyes are defective. Eyes are an important structure of the head, as well as an important structure for humans to see the world. So are human eyes powerful? The answer is no. Walking into the school, we will see that at least half of the students wear myopia. Even among elementary school students, very few can reach the standard vision. This shows that human vision is actually not good, and The function is relatively weak.
In the animal world, there are many animals whose eyes are very powerful. Not only can they clearly see the prey on the ground from an altitude of thousands of meters, but also some animals see the night as day, while the human eyes are at night. If there is no light guide, you are completely blind and can’t see anything.
Humans do not have ding bones. Scientists have found through research that almost all mammals have ding bones, but we humans do not. This bone is very important to male mammals. If humans have this bone, then many male problems can be solved, such as persistence, weakness and other embarrassing problems.
Why don’t humans have Ding Ding bones? Scientists do not have an accurate answer to this. The ancient ancestors of mankind had small and small bones, but in the later evolutionary process, it disappeared. What are the factors that have caused the disappearance of the human body’s T and T bones still need our continuous research and exploration.
The human body cannot synthesize vitamin C. Vitamin C is an essential nutrient for our body. It is very important for our health. The lack of vitamin C can cause major problems in the human body. In the past, scurvy was caused by a severe lack of vitamin C. But even a nutrient that is so important to the human body cannot be synthesized by the human body.
In the animal world, almost all animals can fully produce vitamin C, so we will find that animal teeth are very strong and healthy, and there are basically no dental diseases, but human teeth are relatively weak and often have problems, which leads to Dentistry is very popular, of course, the cost of seeing a doctor is also very large. Therefore, we must protect the teeth, otherwise the later costs will be too much for you to bear.
Humans cannot synthesize vitamin C, which has caused us great inconvenience. Fortunately, fresh fruits and vegetables contain a large amount of vitamin C. We can take vitamin C through these to protect the body’s demand for vitamin C. Therefore, we often hear some health experts say that it makes sense for humans to eat more fruits and vegetables and less meat. If you often don’t eat vegetables and just eat meat, then your body will have various problems, which is what we often call the disease of wealth.
Through the above understanding, we can see that in the process of evolution of the human body, some very unreasonable structures have been born. The human body is not perfect, and there are many defects. Of course, we don’t have to worry too much. With the continuous advancement of human technology, the future powerful genetic technology can correct these defects, so that human beings have a perfect body structure step by step.
