Birth, old age, sickness and death are the laws that most living things have to go through. Whether it is a small animal or a high-level intelligent creature like human beings, from the day of birth, the ultimate destiny is death. In other animal worlds, the fate of life and death is destined, and there will be no resistance to it.
But as the smartest and only intelligent life human beings on earth, they are not so positive about life and death. In the hearts of many people, they are actually very longing for immortality. Even a long-lived elderly who has lived 120 years old, he also hopes to live longer, even immortality.
So why are living creatures bound by the law of life and death? Scientists believe through research that this is a choice made by life on the path of evolution. The early life of the earth was born 4 billion years ago. After the birth of life, there are two choices for the direction of evolution. One is bound by life and death and limited by life, and the other is the road to immortality.
Then why did life choose the evolutionary path of life and death in the end? Isn’t the road to eternal life a better choice? To solve this mystery, we need to think from two aspects, one is survival, and the other is the evolution from low-level to high-level.
Let’s first look at the evolution of life from low-level to high-level. I believe many friends know that the main thread that runs through life is evolution. Only through evolution can life forms continue to evolve from low-level to high-level. This is a macroscopic cognition. From a microscopic point of view, the essence of evolution is the continuous mutation and reorganization of genes.
The gene pool is a huge world. There are countless kinds of genes in this world, and the essence of life is the combination and arrangement of these genes. The evolution of life forms from low-level to high-level requires that these genes undergo repeated mutations and recombination to choose a better combination. When a better combination appears, then the life form has completed an evolutionary evolution and upgraded to a higher level. s life.
But if the organism chooses the path of immortality, then the mutation and combination of this gene will be difficult to proceed. At this time, the organism will not be able to evolve to a higher level of life. We all know that bacteria, its DNA and Human cells are different. Bacterial DNA is circular and can continue to replicate without loss, so in a sense, many single-celled organisms are “immortal” unless they encounter some accident.
The earliest life on the earth was these single-celled bacteria, but because some single-celled life chose the path of immortality, the last billions of years passed, they are still very simple life, unable to become more advanced complex life. If all life on the earth chooses the path of immortality, then the earth will not have mammals, humans and other advanced and complex creatures, but still maintain the most primitive form of life.
Therefore, most of the early life on Earth abandoned the path of immortality and chose another path that was more conducive to evolution. It is this correct choice that caused a major explosion of life on earth, and finally the continuous emergence of advanced life, which was able to give birth to mankind millions of years ago.
Seeing this, many people will say that since the road to immortality is not conducive to the evolution and evolution of life forms, and is not conducive to human beings becoming more advanced beings in the future, then will immortality be only a dream in the human world forever? Of course not. In fact, as humans continue to crack the mystery of life, it will not be difficult to master the mystery of life and death in the future.
After humans have completely solved the mystery of genes, it is not difficult for humans to achieve immortality through genetic means. But at that time, can we do this? The answer is no, because once we choose the path of immortality, it means that the future evolution of human beings to higher life will also be cut off, which may not be a good choice for humans.
Therefore, even if humans master the technology of immortality in the future, this technology will not be able to be popularized by the whole people, but only for a very small number of people, such as those great scientists. In fact, for most people, the happiest thing is to be able to live happier and more exciting lives without the troubles of disease. For ordinary people, immortality will become a burden and a painful thing.
Let us consider from the direction of survival that immortality is not a good choice. The evolution of life has another purpose, which is to survive better in nature’s ever-changing environment. We all know that the earth is a complex and changeable ecological planet, and the ecological environment often undergoes some drastic changes, and if life wants to survive, it needs to be able to better adapt to these drastic changes.
If life chooses immortality and cannot complete the evolution to higher life, then it will not be able to adapt to the ever-changing ecological environment. Although they have the physique of immortality, they are more likely to die in a changeable environment, instead of being able to play the role of immortality.
Secondly, survival is inseparable from resources. The continuation of life requires the support of various resources. If all life forms choose the path of immortality, can the earth’s resources be satisfied? Of course not. Maybe the earth’s resources will be exhausted soon. Without the resources, life will not be able to continue. In the end, the earth will become a desolate planet and completely lose life.
Let us take the current human society as an example. If immortality is realized, what will be the fate of mankind? The answer is destruction. The earth’s resources are a bit reluctant to satisfy the current 7 billion population. But if humans would not die under normal circumstances, the number of humans would increase exponentially. It may not take a hundred years, and every corner of the earth would be full of people.
Under such circumstances, the earth’s ecological environment will be completely deteriorated, and various resources such as food will also face exhaustion. Without a good ecological environment and abundant resources, mankind will usher in the end. Therefore, immortality will not bring any welfare to mankind, but it will bring destruction. Only by following the laws of nature and carrying out the law of life and death, can mankind continue its glory and welcome a better tomorrow.
Of course, with the continuous advancement of human science and technology, in the future we will move towards the sea of stars and colonize various galaxies. At that time, with the help of genetic technology, human life expectancy will also increase dramatically, and the population will explode exponentially. This surge is beneficial to mankind, because we are no longer confined to the earth, no longer confined to a small solar system.
It can be seen that the longer the human lifespan is, the better, and the longer it is, the more beneficial it is for humans, but it needs to be determined according to the pace of human development. We have more living planets and a broader living space before we can increase our lifespan by a large margin. If we have been nesting on the earth, the life span of human beings will not be able to increase substantially, otherwise it will bring a crisis of destruction to mankind.
