But in fact, many people are very nervous about this genetic engineering thing. Originally, this thing is a bit unreliable, especially now people are not particularly in-depth in research on disciplines such as genetic engineering. Even Chen Yuan himself does not have a relatively complete ability to compare these things.

It can be said that he doesn't understand, but in general, some of the issues involved in it seem rather unsatisfactory.

Lu Jian also raised his questions during the meeting.

"The genetic differences between humans and chimpanzees are only one percent. We don't regard them as humans, but we still have to be locked in cages. The "superman" produced after some transformation may be called super living organisms. What will they think of us native species?"

Physiologically, it's not human anymore, but psychologically, it's also very difficult.

In fact, Chen Yuan has considered these issues that Lu Jian said. Changing genes can only do it for one cell, and then let the cell develop into a complete life form.

Therefore, we cannot first instill a set of human values ​​so that he can feel that he is the same as us and should love each other.

"In this way, if humans really do this one day, they will probably not get superheroes, but super monsters that their relatives do not recognize. They will probably destroy humans without hesitation and then build a stronger civilization."

Wang Shenlan thought about this carefully and felt that the future might still be quite terrible.

Chen Yuan didn't know how to deny it, but he couldn't affirm this matter either. He just shook his head, "Humans have been born on the earth for millions of years. In this long process of development, human beings' abilities are getting stronger and stronger, and technology is becoming more and more advanced. Human beings have also become intelligent life on the earth, dominating all resources on the earth, occupying a high position.

However, no matter how human beings develop, we must follow the laws of natural development. No matter how we develop, we cannot break the constraints of the laws of natural development, so human beings cannot achieve eternal life. In history, many people wanted to live forever. In ancient China, Qin Shihuang specially sent people to refine elixirs, but this elixir was refined after Qin Shihuang's death, so eternal life is unrealistic."

Everything on the earth will fall one day. Human life span is only a few decades and is still very short, but there are still people who are curious. With the development of human technology, why can't humans achieve immortality?

"Biologists tell you the answer, but it's mainly because our genes don't allow it."

But Chen Yuanming knew it was not feasible but insisted on working on genetic engineering.

So how long does a human life span last?

Will he create an era of immortality in the future? The number of discussions on issues like these and other online will begin to grow unprecedentedly. After all, this is the thing that everyone is most interested in.

"How long a human life span depends not on ourselves, but on our genes. So humans live in this world like a "tool person", because we cannot determine our life span, we can only rely on genes. Our physical condition, appearance, etc. are determined by our genes."

"Human lifespan is related to telomeres DNA. Telomeres DNA exists at both ends of our chromosomes. The longer the telomeres DNA, the longer the lifespan. The shorter the telomeres DNA, the shorter the lifespan. There are many cells in the human body, and all cells will divide. When DNA molecules divide and replicate, telomeres will shorten a little. The more times a cell divides, the more its telomeres wear out, and the shorter its lifespan will be. Once the telomeres are exhausted, the cells will immediately activate the apoptosis mechanism, and then the cells will go to apoptosis, and the human lifespan will come to an end."

“So we cannot obtain eternal life.”

In many discussions, a fact is right before us, and humans live on the earth like "tool people", just like completing a certain mission.

Here, some people have once wondered, since genes determine the lifespan of humans, can humans extend their lifespan by modifying genes and thus achieve the goal of immortality?

This also confirms what Chen Yuan plans to do now.

"From the current technology of human beings, it is impossible for humans to realize this technology. Even if humans' technology in the future is advanced enough to modify human genes, this technology cannot be applied to our lives, because once applied to our lives, it will inevitably violate the laws of natural development, and human development will be chaotic, so this method cannot be achieved."

Netizens went straight to the hotly discussed discussions in the live broadcast room, venting the issues they thought, worry and concern from the bottom of their hearts.

When someone asked Chen Yuan how to carry out the genetic engineering project, Chen Yuan did not give a clear answer. Instead, he immediately formed a large number of scholars and began to carry out related research. Long Weiguo, who had never been involved in the world, also took the initiative to find Chen Yuan at this time.

To be honest, it was a normal thing for him to come to Chen Yuan this time. After all, genetic engineering involves the speed of immortality, and Long Weiguo is old, so who doesn’t want to live forever, right?

"Xiao Chen, can the genetic engineering you mentioned really be implemented?" Long Weiguo asked impatiently.

Chen Yuan shook his head and did not give a positive answer.

This is really hard to say.

“There are many problems involved in wanting a person’s lifespan to exceed the limit.

So is there no way?"

Long Weiguo seemed a little anxious, Chen Yuan shook his head, "It's not that there is no way."

"Now medicine has found that the normal life span of humans should be between 130 and 150 years old, but this does not represent the upper limit of human life. The main reason for life is the limit of cell division - cells can only divide by 50 to 60 times and die. Moreover, most organisms on the earth meet this rule, but there are still a few organisms that can ignore this rule and survive on the earth, including the lobsters we are very familiar with."

The difference between lobsters and other organisms is that every time they change their shells, it is like changing a new body. Theoretically, lobsters will not die due to aging. At present, the oldest lobster has lived for more than 130 years and is still growing. The reason why lobsters do not age is because they rely on shell replacement to reset the cells in the body. The reason for human aging is that cell division has reached the upper limit. Of course, lobsters will become larger every time they change shells, making them more likely to be discovered by natural enemies. Even if lobsters have such a terrifying ability, it is difficult to escape the delicate balance of nature.

The method of "changing shells and immortality" in lobsters also hopes that scientists can achieve it in humans. Since the cells in the body have an upper limit of division, can the replacement of aging sites break through the aging mechanism? Obviously, this type of field is still in the stage of preliminary exploration, and it has only found a way to avoid cell aging. However, there is also a creature in nature that achieves immortality through "rejuvenation" method - a lighthouse jellyfish.

Of course, there is another animal, that is, the everlasting lighthouse jellyfish

In the 1990s, scientists accidentally discovered that the lighthouse jellyfish would transform into a larval state in a harsh environment. When the environment returns to normal, this larval body would regenerate into a jellyfish. The strange growth method of lighthouse jellyfish was directly called "animal that will not die" in 2010. The lighthouse jellyfish was an anchor-shaped hydrate body in childhood, and it did not gradually grow an umbrella body after adulthood. When the lighthouse jellyfish began to return to its juvenile period, the cells in its body would become stem cell state.

Then it can also be redeveloped into tissues and organs, which is also the first organism discovered in nature that can transform somatic cells into stem cells!

There are even leech-shaped rotifers that cannot be killed.

"Maybe most people know that the water bear insect is a microorganism with super strong vitality, but there is a kind of leech-shaped rotifer living in water that is more powerful than the water bear insect. It can survive in any extreme environment like the water bear insect. Even in a super-radiated environment, it cannot kill it. And after leaving the radiation environment, the leech-shaped rotifer insect can repair the DNA destroyed by radiation. Although the water bear insect has strong vitality, it does not have the ability to repair DNA. This microorganism was first discovered by Levinhoek, the father of the microscope. At the same time, it questioned how this unisexual reproductive microorganism evolved itself." Chen Yuan said.

Although human aging is caused by the shortening of telomeres of chromosomes, natural death is normal for the entire ecological chain from a scientific perspective, because life can replace new and old in the first place to evolve more perfectly. Aging is the best choice for survival of the fittest in nature. Once a living individual stops evolution, it will inevitably lead to decline. Only when a living body changes in new and old in the first place can the population be more adapted to the environment.

Moreover, these creatures that seem to not aging or die have not become the top of the biological chain. Obviously, the mechanism of immortality does not give them enough advantages. It is precisely because their vitality is not tenacious enough that these abilities are needed to achieve the continuation of the population. The current medical field has always hoped to implant genes of other organisms in the human body.

However, are these new humans who have changed dna or humans?

Genetic engineering can prolong human life span, but no one can stand the thing about immortality because of life.

It is bound by nature. Therefore, under this principle of nature, grow and expand as much as possible, but you cannot violate this law, that is, nature does not allow any creature to live and die forever.

With the development of human science and technology to this day, I feel that their technological level is very high, but you can think about it yourself. The five generations of civilizations that appeared before humans are not civilized or biological. It may be that humans have appeared in the world for a year, only five or six million years. They have existed for so long. Haven’t they been purified? Didn’t they think about extending their lives? Humans have their own wisdom for five or six million years, and they must have their own direction, but in the end they all became extinct.

Because nature does not allow any species to survive forever.

In the face of nature, the reality is that it is vulnerable. Don’t think that your technology has become very powerful now. If nature really gets angry, the things that humans have now will be destroyed before treating guests. Because there have been so many turmoil on the earth before, almost all the creatures on it have become extinct, and more than 90% of them have been extinct. However, after millions of years or even longer, the earth can still recover.

Humans only rely strictly on the earth to survive, but the earth does not rely on humans. Without humans, the earth can continue to exist, but humans cannot.

Genetic engineering is a way for humans to interpret their genes through technology, and in this way, people can extend their lifespan. For example, the average lifespan of humans is 70 to 80 years old now. Is it possible to extend it to 150 years in the future? This is possible. However, if humans can never die and continue to exist, the laws of nature will not allow it. Not only humans have thought so, so many creatures must have had all kinds of strange ideas before, but facts have proved that no species can resist the power of nature.

But Chen Yuan did not completely believe this.

There is no law in the development of nature, and perhaps the entire universe has no law in it.

After all, everything is accompanied by some unrealistic feelings, and you have no idea what will happen in the future.

However, although humans seem fragile, they have a lot of things to do.

"I believe that with our efforts, genetic engineering will definitely make progress."

Chen Yuan said so affirmatively, which also allowed Long Weiguo to see unprecedented hope in his eyes.

He believed that Chen Yuan could do it, after all, this child has been bringing hope to mankind since a long time ago.

Endless hope.

"I believe in you, and I also believe that humans can wait for this day." Whether it is out of trust in Chen Yuan or the future development of mankind, Long Weiguo is very supportive of Chen Yuan.

When the genetic engineering project was spread, the whole of China began to boil.

In particular, many people are paying attention to the genetic engineering project, and even a lot of capital has started related discussions.

After all, in their opinion, achieving this brilliant feat is something that mankind and this ethnic group need to work together.

Of course, Chen Yuan is not a fool. He knows that for those capitals, what they are most concerned about is not whether the genetic process can be successful, but the commercial value brought by it.

You should know that the industrial achievements brought by any high-tech are very impressive, especially related science and technology, which makes people feel obsessed.

But compared to these things, the most obsessive and even irresistible thing is perhaps eternal life.

Especially for those rich.

Let me ask, if you tell them that as long as you give enough money, you can achieve eternal life, do you think they will refuse?

Of course not
