Many people suffer from physical disabilities due to accidents. Especially in the war years, the cruelty of the battlefield made many people lack arms and legs. Even in modern times, there are many disabled people with limbs.
I believe many people will think: It would be great if the four feet of human beings could be broken and regenerated like some animals. I believe many friends know that the regeneration of limbs is not a myth in the animal world, but a real thing. There are some animals with super strong limb regeneration capabilities, such as deer, geckos, salamanders, lizards, crabs, etc. .
These inferior creatures in our view, they all have the ability to regenerate limbs that we envy. The gecko’s tail can grow back; the limbs of the salamander can also be lost and resurrected. Many friends thought: If humans have such abilities, it would be a happy thing. Humans no longer have to worry about limbs being mutilated.
So, a question arises here: Why can’t humans regenerate their limbs like some animals? We must know what a boon for amputees if such regenerative ability exists. In the animal world, such superpowers exist in many animals. We drop the legs of the salamander and it will grow back soon.
In fact, humans also have part of this regenerative ability, such as: our skin epidermis is damaged; in less serious cases, the healing of skin cells will not produce scars, which is regarded as a kind of cell regeneration; another example is the human liver. If a small part is cut off and the liver grows out again, it can be regarded as organ regeneration.
It can be seen that the regenerative ability of life is more or less present in every animal, and humans also have some regenerative ability. It’s just that we can only regenerate part of it, and we don’t have advanced regenerative abilities like limbs. This makes many people feel calm. Lower creatures have such a powerful regenerative ability. Why don’t humans ?
Some people may say that this is nature’s unfairness to mankind, and it has not given mankind such a powerful regenerative ability. But in fact, nature is very fair on the path of biological evolution. Where the evolution of each species is, nature is proceeding according to the law of survival of the fittest.
We all know that from the perspective of evolution, all creatures in this world have a common ancestor, and the ancestors of human beings evolved from lower creatures. Before humans became higher creatures, they might have the same limb regeneration ability as lower creatures, but in the later evolutionary process, humans lost the function of limb regeneration.
Some friends may have said, why do humans lose such powerful functions? In fact, there is no alternative. We must know that since human beings have embarked on the path of intelligent evolution, we have given up a lot for the development and rapid evolution of the brain.
The brain is a complex structure, and it has a very large energy demand. The more developed the brain, the greater the energy demand. The weight of the human brain only accounts for about 2% of the body’s weight, but the energy consumed accounts for 20% of the body’s energy, which is a big energy consumer.
The powerful function of limb regeneration inevitably needs more energy to support. The reason why some lower organisms can maintain this powerful function is precisely because their brains are simple and do not require much energy to support. More energy to support limb regeneration.
But the more advanced the creature, the more developed the brain, and the more energy it needs. If at this time, the organism continues to retain the function of limb regeneration, then the energy of the organism will not be reasonably distributed, and the final result will be the collapse of the organism.
In the process of biological evolution, nature must also consider the ratio of energy requirements of various biological tissues in order to achieve a balanced state. If humans want to retain the ability to regenerate their limbs, it will inevitably occupy a part of the energy needed for brain evolution, so that the road of human intelligence evolution will be greatly slowed down, and it may not even become a true intelligent life.
Therefore, in order for human intelligence to evolve faster and more safely, nature can only let humans give up the ability to regenerate their limbs. In addition to this powerful function, humans’ physical fitness is also very weak compared to many mammals. This is actually a helpless choice that humans have to make in order to evolve intelligence.
This shows that human beings have indeed given up a lot of things in order to evolve and evolve intelligence. Of course, it is undoubtedly a correct choice for mankind to abandon these and embark on the path of wisdom evolution, because only wisdom can have an infinite future.
Nowadays, human beings have embarked on the road of science and technology, and the power of science and technology is powerful, as long as we can continue along the road of science and technology. Then the mystery of life will be revealed step by step by us. At that time, perhaps humans still hope to regain the ability to regenerate their limbs through powerful genetic technology.
In fact, scientists have been studying the possibility of human limb regeneration. The ability of some lower animals to regenerate limbs must be affected by some of their cells and genes. As long as we can find these cells and genes that affect the regeneration of limbs, it is possible to achieve regeneration of human limbs.
The latest research by German scientists found that there is a peculiar enzyme (amblox) in the salamander that can regenerate its limbs and organs. Scientists believe that the artificial synthesis of this enzyme is expected to allow people who have lost limbs and certain organs to regenerate new limbs and organs.
Scientists explore the secrets of organisms with the ability to regenerate limbs to unravel the mystery behind limb regeneration step by step. As long as we work hard, I believe that in the near future, the disabled will disappear from this world. As long as we still have a breath, no matter which part is missing, it may grow back.
