Clones were created 23 years ago, so why not clone people?

With the development of science and technology, various new technologies emerge one after another. Some of them are quite controversial, for example, cloning technology. In 1996, humans succeeded in cloning a sheep named Dolly.

From a technical point of view, cloning a human is not difficult. Why don't scientists clone humans?

1. Short life and many diseases

Through the 1996 clone of Dolly, we can find that although it was successfully born, it will not suffer from an incurable disease in a few years. As the first cloned organism, scientists studied the final data after his death, discovering many problems in cloning technology. It is necessary to know that an ordinary sheep can live for 12 years, but it can only live half of it.

Geneticists have been even more outspoken, saying that genetic defects in cloned organisms are inevitable, that cloning technology is indeed seriously problematic, and that its premature aging is even more unexpected.

2. Ethics and morality

Clones and hosts are genetically identical, but if they are humans, they will face all kinds of inconveniences in real life. Even some scientists still don't recognize clones as real people. The clone may have two or three parents, but who is his own biological parent, it's an indescribable relationship.

3. The original intention of cloning technology

Cloning technology should be widely used in the field of human medicine, and it can play an incomparable role in overcoming genetic diseases and organ transplantation, which can save the precious lives of thousands of people. At present, many countries have made it clear that they support the research of "sexual cloning" technology, hoping that this technology will eventually benefit mankind.

It is "very inhumane" to apply this extremely immature technology to humans. If a clone has a physical defect, the clone will not be able to escape responsibility.

<> want to clone people, this will face many problems, one is because of the immaturity of technology, you must know that the first cloned sheep Dolly was successfully succeeded after 227 failures, there are still many problems in cloning, a creature its existence is not simple, and it is a problem to completely clone it, which is a major problem in technology.

Second, the failure rate is high and the time is long. There are all kinds of failures in the cloning technology, and every link that goes wrong will lead to the failure of the later results, and on the basis of cloning, a variety of conditions need to be met, which can almost be said to be indispensable, and if you want to clone everyone, everyone can be said to be changing all the time, Today is like this, he is going to clone this, and when everything is ready to be only owed to the east wind, this person has changed again, what to do, and as a person, He has two major influencing factors, congenital and acquired, if he only imitates the innate factors of this person, it seems that he cannot be called a clone, if you want to clone his innate and acquired factors, there are many variables, which undoubtedly increases the difficulty. <>

The third and most important ethical issue, since the first appearance of sheep cloning technology, people have begun to think about whether human cloning can be a problem, and after this question, they will find many more profound problems, which is undoubtedly a major challenge to human morality and ethics.

And, the cloned sheep Dolly eventually lived to be 6 years old, and died of lung cancer and arthritis, you know, the normal lifespan of the average sheep should be about 12 years old, and the cloned sheep only lived to half the life of the normal sheep. <>

So far, not only in China, but also in many countries, it has explicitly banned the technology that does not allow the research of human cloning, and it is possible to clone human organs.

This one is because everyone should be protected for privacy, so cloning is not allowed.

This is because human cloning is not a humane act. Everyone is unique.

Buddhism's description of our life in this world has four natural birth methods, oviparous, viviparous, metaplasia, wet, the earliest human beings are mostly metamorphosis, as well as oviparous and wet human phenomena, if the cloning is successful, then the Buddhist explanation can only be called, artificial intervention of oviparous phenomenon, because the principle of cloning is cultivated with cell activation, just like eggs, eggs are a relatively large cell, eggs are equivalent to natural oviparous reproduction, and human cloning is an unnatural way to complete oviparous phenomena, It is recorded in Buddhist scriptures that a pair of Upollo brothers hatched from eggs, which is amazing, and you may not be able to understand oviparous people without scientific research.

This is because if the creation of human cloning is carried out, it will affect ecological equity.

I think it's unethical to say something like this.

Clonal organisms may also have a relatively short lifespan due to their own genetic instability

In 1997, a sensational event occurred in the world of biology: the birth of Dolly the cloned sheep.

On the outskirts of Edinburgh, 10 kilometres from the city, there is the village of Rosslyn, a scenic "hideaway". The Rosslyn Institute is home to the UK's largest livestock and poultry research institute and a world-renowned biological research centre, where Dolly the cloned sheep was born.

July 5, 1996 was an exciting day for all members of the Ian Wilmut Scientific Research Group at the Roslin Institute; It's also a day to celebrate for the whole world. Because a little sheep that was 148 days pregnant, weighed 6 6 kilograms, and was numbered 6ll3, came into the world, it was "copied" by scientists using cloning technology.

After months of careful care, this extraordinary little sheep thrived and received a catchy name - Dolly. It was named after his beloved country singer, Dolly Parton.

A damn doctor who will "go astray" of humanity.

Ian Wilmut and the group he leads.

Dolly the little sheep is the most well-known sheep in the world. Her birth was like an earth-shattering shock, triggering a "Dolly" storm that swept the world.

On February 27, 1997, the British journal Nature reported a research result that shocked the world: seven months ago, the Roslin Institute used cloning technology to breed a ewe, "Dolly". This is the world's first sheep to be "cloned" from mature somatic cells (mammary cells).

"Dolly" is produced using somatic cell nuclear transfer technology, and the general steps are: implanting the mammary nucleus of a female sheep into an unfertilized egg from which the nucleus has been removed from another female sheep to form a blastocyst; It is then transplanted into the womb of the third ewe, which is pregnant and gives birth to a young sheep that is genetically identical to that of the donor ewe. The genetic traits of the resulting sheep are almost identical to those of the donor sheep, which can be said to be a replica of the asexual reproduction of the donor sheep, that is, the "cloned sheep".

Cloning is to use a single cell as the mother cell to reproduce cell groups and individual populations, which is essentially a kind of asexual reproduction. Cloning technology is also called nuclear transfer technology. The scientific significance of the birth of cloned sheep is that for the first time, animal somatic cells were used as nuclear donors to complete nuclear transfer.

The breakthrough progress of cloning technology will play a major role in promoting agriculture, animal husbandry and aquatic products, environmental protection, pharmaceutical industry, biomedical engineering research, etc.: cloning technology may replicate organs and tissues that do not reject the human body, and improve the success rate of organ transplantation; Replicating animal genes and manufacturing immune preparations have opened up a new world for the diagnosis, prevention, and development of immune diseases, infectious diseases, cancer, etc.; selectively breeding rare animals to save endangered species; Cultivating and preserving excellent varieties of plants and animals.

However, cloning also has the potential to bring unforeseen disasters to humanity. For example, the ethical controversy caused by "human cloning" is still boiling to this day. In conclusion, the birth of cloned sheep shows that humanity's ability to understand and manipulate life is increasing at an unprecedented rate.

The 21st century has also been called the "century of biology" by many scientists and people of insight.

The stalk of cloned sheep not living to be 6 years old describes irony, referring to people who follow the trend, imitate, and plagiarize others, and they will not end well.

Because Dolly is a female sheep created through modern engineering, and the first artificial animal to be successfully cloned at the beginning of the world, but survived for six years before dying, and is now mostly used to mock plagiarists.

There are several explanations for why Dolly the cloned sheep only survived for six and a half years:

One is that cloned animals will have premature aging, and their body age from birth is similar to that of cloned individuals. That is to say, from the time they are born, they are already in a state of continuous life, so their lifespan is shortened compared to normal birth animals.

Second, the cloning process will involve many physical and chemical experiments, and the harm of these experiments to cloned animals cannot be underestimated. Most cloned animals die before they form embryos, and most of them are malformed after birth due to this reason. It was not easy for Dolly to be born and grow to the age of 6.

Third, lung infections are common diseases in sheep, especially those bred indoors. And Dolly herself is a very special sheep, and the disease she suffers from happens to be an extremely special incurable disease. That normal creature can't avoid disease, let alone clone.

The cloned sheep lived for 6 years. Dolly the cloned sheep is a sheep created through modern engineering, and the first mammal to be successfully cloned at the beginning of the world, sheep usually live for about 12 years, and Dolly only lived 6 years because the cloned object was already 6 years old.

Cloning refers to the asexual reproduction of an organism through somatic cells, as well as the formation of asexual reproduction of an identical genotype.

The word "cloning" is a transliteration of the English "clone" or "cloning", and the exact words for cloning in Chinese are "asexual reproduction", "clones", and "pure lineage".

The birth of Dolly the cloned sheep is a great leap forward in the cloning achievements of the scientific community, and it was rated as the first of the world's top ten scientific and technological advances in 1997 by the American magazine Science.
