Hundreds of years ago, mankind entered the road of technological development, and the power of science and technology allowed mankind to see unlimited possibilities. This may not only explore the mysteries of things, explore the mysteries of the universe, but also let us see the hope of uncovering the mysteries of life.
We must understand that the vast universe has many complex and mysterious things, and life can be called the most mysterious thing. Perhaps only by completely uncovering the mysteries of life can we become a truly powerful civilization in the universe.
Mankind entered the age of science and technology and began to conduct exploration and research in different fields of industry, among which biotechnology is the field of exploring the mysteries of life. With the help of science and technology, human beings have more and more understanding of life, and using the mysteries of life that have already been understood, scientists have also begun various application attempts.
I believe many people remember that at the end of the last century, the discussion and research on “cloning” was very hot. At that time, we could often see related topics about cloning on the Internet, in newspapers and various media reports. Research and explore. But now we will find a strange phenomenon, that is, “cloning” is rarely mentioned in the scientific community now. What is going on?
In fact, to unravel this mystery, we have to find the answer from a cloned sheep named “Dolly”. First, let’s understand what is cloning? The so-called cloning is actually the process of using biotechnology to produce offspring with exactly the same genetic tissue as the original individual from asexual reproduction. Scientists call the process of artificial genetic manipulation of animal reproduction as cloning.
For asexual reproduction, I believe many friends know that there are many kinds of asexual reproduction in nature, and they are basically in the plant kingdom, but there are very few asexual reproduction methods in the animal kingdom. The advantage of asexual reproduction is that it develops quickly and can spread 100% of itself to the next generation. Early life on the earth reproduced asexually, but this method of reproduction could not achieve mutational renewal of genes, and it was difficult for living organisms to evolve and grow into more advanced life.
Therefore, in the end, nature gave up this method of reproduction and allowed most organisms to choose sexual reproduction, so that the rapid evolution and evolution of life can be realized.
Cloning is actually a way of asexual reproduction under artificial intervention. Individuals or populations cloned under artificial intervention have exactly the same set of genetic genes as the donor cells. It can be said that this cloned population has the same appearance as the mother, but has different behaviors and thoughts.
On July 5, 1996, the world’s first “Dolly” cloned sheep created through modern biotechnology was born. Its birth has aroused the attention of the whole world, whether it is scientists, the social circles or the religious circles have paid high attention to this special “Dolly” sheep.
This cloned sheep was a star in the world at the end of the last century. In a few years, news about it will often appear in major media. The reason why people pay so much attention to it is because it is not an ordinary cloned sheep. Although scientists have done biological cloning in the past, those cloned organisms only use semi-clonal biotechnology.
And this “Dolly” sheep can be regarded as a true cloning biotechnology. Its appearance indicates that human cloning biotechnology has entered a new era. Significant milestone. For biologists, the great leap in cloning technology is of great significance to mankind. But for some sociologists and people in other fields, the leap of cloning technology may not be a good thing.
Any technology has its two sides, and cloning is no exception. When applied well, it can bring good news to mankind, but if it is not applied well, it will become a disaster. For many people, cloned sheep can be successful, does that mean that human cloning can also be successful?
Cloning animals is acceptable to people, but it is believed that human cloning will bring serious social and ethical problems. No one wants to see that there are many brothers or sisters who look exactly like you and have exactly the same genes. This cloned group is completely a copy of you. However, they are also independent individuals and have different thoughts from you. Do you think they should be called your brother, sister, or father or mother? Or are they yourself? How do you deal with this complicated relationship?
It is precisely because once the cloning biotechnology is fully mature, it may bring serious ethical problems to human society and mess up the entire human civilization, so people all over the world are very concerned about this “Dolly” cloned sheep, and we can use it. I learned to what extent humans have mastered cloning. But the final result is believed to be known to many friends.
Dolly only lived for about 6 years. It is important to know that the life expectancy of the average sheep is between 11 and 12 years old. Dolly only lived half of their lifespan. Although Dolly was also a baby lamb when she was born, she was a replica of a 6-year-old white-faced sheep, so she was already 6 years old when she was born. We can call it a 6-year-old baby.
This is obviously a kind of premature aging. In addition, Dolly’s life has been plagued by many diseases. She has changed into many senile diseases at a young age, such as arthritis. She died of lung infections at the time of her prime. Can be “happy” to die. Through Dolly’s life, we have seen that cloning biotechnology is far more complicated than we imagined, and humans may only be able to master it.
In other words, the cloning technology currently possessed by humans is not yet mature. In order to verify this answer, after Dolly, scientists have cloned some individuals who are the same as Dolly, but the final result is the same. There are also the problems of premature aging and various diseases in Dolly. The results of many experiments finally let us understand that the existing human cloning biotechnology is indeed very immature.
From then on, those who were worried that human cloning would bring social problems no longer spoke up, and the scientific community rarely mentioned the issue of cloning. So does the cloning research end and give up? Of course not. In fact, cloning has an epoch-making effect on the future of mankind. It can be said that it can change the future of mankind, and it is still of great benefit to mankind.
Human cloning will face many social and ethical problems, but cloning organs will not have so many problems. I believe many friends know that many people lose their lives due to diseases every year, and many diseases that can take human lives are related to organs. However, in the real world, very few people can achieve organ transplantation. Most people do not have the financial strength, and the other is lack of matching organ transplants.
Even if the transplantation is successful after spending a lot of money, it cannot achieve a 100% match. In the later stage, it will face various rejections and use drugs to maintain it, and it will become a lifelong medicine jar. At the same time, life expectancy will be reduced, but if human cloning biotechnology is mature and can clone 100% matching organs, then the rejection after successful transplantation will basically be non-existent, and it will be exactly the same as the original organs in your body.
With this technology, people no longer worry about losing their lives because of organ problems. Even healthy people without disease will continue to age and their organs will continue to age over time. At this time, we can also choose to replace organs. With new and powerful organs, human functions will be greatly improved. Human life expectancy will also increase significantly. I believe that no one can refuse such a good thing.
So whether human cloning will not reappear in the future, the answer is no, although in the earth age, when social and ethical issues are involved, human cloning will basically not occur. But if human beings enter the interstellar era in the future, when interstellar exploration and colonization are started, human cloning may play a huge role.
We all know that the universe is vast and vast, and the distance is based on light-years, and it may be an extremely distant thing for human spacecraft to achieve the speed of light or even the speed of light. What if we need to explore a distant starry sky or colonize a distant planet after humans have initially achieved subluminal flight?
It is necessary to know that the time required for interstellar voyage is long, and it may take at least thousands of years to set off from the earth to the target galaxy. Such a long period of time, it takes 10 generations to complete the life span of a human being only about a hundred years. In this way, human beings starting from the earth cannot wait to reach the target planet. What should we do at this time? Cloning is about to play a major role.
The future era is the era of artificial intelligence. Artificial intelligence will become an important helper for mankind. We can send an unmanned interstellar spacecraft with advanced artificial intelligence on it. At the same time, there are many cultivation chambers, these cultivation chambers are used to clone people, after the interstellar spacecraft has sailed for more than a thousand years to reach the target galaxy.
Artificial intelligence can perform the operation of cloning humans through instructions. The new human beings are born to allow artificial intelligence to train and educate. When they grow up, the spacecraft will just reach the target galaxy. In this way, human beings will be available for exploring galaxies or colonizing planets. In this way, human beings can complete the path of galaxy colonization, spreading the footsteps of human beings in the vast universe.
It can be seen that cloning biotechnology is very important to mankind. As long as we make good use of it, the benefits it brings to mankind far exceed our imagination. Of course, if you don’t apply it reasonably, but mess around, it may really bring terrible disasters to human civilization.
