Chapter 946 World in Turmoil
Not long after the Spring Festival, a major event caused a sensation around the world.
On February 27, the British magazine Nature announced that the Roslin Institute in Edinburgh successfully asexually reproduced the sheep 'Dolly' 7 months ago.
The cloned sheep 'Dolly' can be said to be a milestone in the history of bioengineering!
As soon as the news came out, it caused a great sensation, and public opinion quickly divided into two camps, one supporting the development of cloning technology, and the other opposing cloning technology!
Cloning technology is the process of using biotechnology to produce offspring with exactly the same genetic tissue as the original individual through asexual reproduction. Scientists call the process of artificial genetic manipulation of animal reproduction cloning, and this biotechnology is called cloning technology, which means asexual reproduction.
Cloning technology is not new. In fact, up to now, cloning technology has gone through three stages of development.
The first stage is microbial cloning, that is, using a bacterium to quickly replicate thousands of bacteria that are exactly the same as it, and become a bacterial group.
The second stage is biotechnology cloning, such as using genetic genes-DNA cloning.
The third stage is animal cloning, that is, cloning an animal from a cell.
The cloned sheep Dolly was cloned from the somatic cells of a ewe using animal cloning technology.
The birth of the sheep Dolly caused an uproar in the world. The special thing about it is that there was no sperm involved in the birth of her life. The researchers first sucked out the genetic material from a sheep egg cell, turning it into an empty shell, and then took a mammary cell from a 6-year-old ewe and injected the genetic material into the empty egg cell shell. In this way, an egg cell containing new genetic material but not fertilized was obtained. This modified egg cell divided and proliferated to form an embryo, which was then implanted into the uterus of another ewe. With the successful delivery of the ewe, "Dolly" came into the world.
Before, other cloned animals did not have such a big impact on the world. The reason is naturally that the genetic genes of other cloned animals come from embryos, and they are all nuclear transplants using embryonic cells, which cannot be strictly said to be "asexual reproduction." Another reason is that embryonic cells themselves reproduce sexually, and half of the genome in their cell nuclei comes from the father and half from the mother.
Cloning is a major technological breakthrough in the field of biological sciences, reflecting the progress of cell nuclear differentiation technology, cell culture and control technology.
However, the major breakthrough in animal cloning technology has also brought widespread controversy.
The benefits of cloning technology are obvious. For example, cloning technology can relieve the pain of women who cannot become mothers. The implementation of cloning experiments has promoted the development of genetics and opened up prospects for "manufacturing" animal organs that can be transplanted into the human body. Cloning technology can be used to detect genetic defects in fetuses. Cloning technology can be used to treat damage to the nervous system. In in vitro fertilization surgery, one egg cell can be cloned into multiple cells for fertilization, thereby greatly improving the success rate of pregnancy.
However, there are also many disadvantages. For example, cloning will reduce genetic variation. Individuals produced by cloning have the same genetic genes and the same disease sensitivity. One disease can destroy the entire cloned population. It can be imagined that if a country's cattle are all cloned products, a virus that is not serious may destroy the country's animal husbandry.
In addition, the use of cloning technology will make people tend to reproduce the most valuable individuals in the existing population in large quantities, rather than promoting the survival of the fittest in the entire population according to natural laws. In this sense, cloning technology interferes with the natural evolution process.
In addition, cloning technology is an expensive technology that requires a lot of money and the participation of biological professionals, and the failure rate is very high. Dolly is the only result of 277 experiments.
Of course, the biggest drawback is that cloning technology can be used to create "supermen", or people with strong physiques but low intelligence, and if cloning technology can be effectively used in humans, men will lose their genetic significance.
The impact of cloning technology on family relationships will also be huge. A child cloned from his father's DNA can be regarded as his father's twin brother, but his birth is delayed by several decades. It is hard to imagine how a person would feel when he (she) finds out that he (she) is just a complete copy of another person?
The whole world was stirred up by the cloned sheep "Dolly", and the angry British even smashed the Roslin Institute in Edinburgh.
Countless people demanded that the country ban cloning technology.
In this disturbance, the situation in Africa, which no one paid attention to, got further out of control.
The war in Algeria spread to Mali, Niger, Chad, Sudan, Congo, and Nigeria.
It can be said that most of Africa is in the flames of war.
Religious reasons, tribal reasons, economic reasons, and reasons for the game between major powers.
France was furious and sent troops to Africa to stabilize the situation.
France must not lose its interests in Africa. With its interests in Africa, France is a world-class country. If it loses Africa, France will never succeed!
Liu Tao looked at the intelligence and frowned slightly. To be honest, the situation was out of control this time, which was beyond Liu Tao's expectations.
In his plan, all this should be subtle and slow, without war.
Because construction is not easy, destruction is very easy.
But plans often cannot keep up with changes, there are too many factors.
Americans are now very strategic and will not start a war, but that does not mean that the CIA cannot make trouble. The CIA is behind the out-of-control situation in Africa this time.
Americans may not be able to accomplish one thing now, but they often have the ability to prevent others from doing one thing.
The goal of the CIA this time is the interests of the French in Africa.
As long as the war breaks out, the existing order will be impacted and disrupted, and then it is very suitable to fish in troubled waters in such a chaotic situation.
No wonder the French are furious.
Because once these African countries are in war, the biggest losses are the French.
What is even more horrifying is that the CIA is pushing refugees from these war-torn countries in Africa to go to Europe.
For Africans, Europe is a developed country with high social welfare. It is undoubtedly a paradise. They usually try their best to go to Europe, not to mention during wars.
Some European media continue to advocate that European countries should accept some African refugees out of humanitarianism, and claim that this is Europe's atonement for the African slave trade.
Some European charitable foundations carried boatloads of African refugees to the United States, and after being rejected by the Americans, they were placed at the US-Mexico border.
The two sides were fighting, and they were having a lot of fun.
Even some Latin American refugees suddenly kept heading to the border, intending to go to the United States, the beacon of humanity and the paradise on earth.
