In February 1997, British scientists announced that the cloned Dolly was born in July 1996, making the term "clone" almost familiar to most of the public almost overnight. When it was combined with the word "human" to form the term "clone", some people began to get excited, and others started to fear. The bright prospects of being over-exaggerated, the exaggerated situation of terror, and the diverse views of science, ethics, religion, law, and society are entwined, making more people feel puzzled and confused about the development of cloning technology. How far can cloning technology go? The research and application of cloning technology in animals does not have too many restricted areas. Many countries are accelerating research to use cloning techniques to cultivate new breeds of livestock, save endangered animals, and produce raw materials for drugs. However, when cloning techniques involve humans themselves, the debate is much greater. At the symposium titled "Biomedical Research and Cloning Technology in Reproduction" that concluded in Berlin, Germany on May 16, 2004, several experts in cloning problems in various fields basically reached a consensus and cloned the genital clones. Into the forbidden zone of the development of cloning technology, but for the study of medical cloning, but still controversial. It has been nearly 7 years since Dollyin was born. Sheep, cows, pigs, mice, rabbits, cats and even monkeys have the cloned versions of primates that are most similar to human characteristics. However, there is no doubt that cloning technology is still in its "embryonic state." Humankind must achieve the goal of full mastery and safe use of cloning technology. The road is long and winding. Griffin, director of the Rothlyn Institute in Scotland, who cultivated Dolly, pointed out that on average, only 1%-2% of cloned embryos survived in all animal cloning experiments. Although this proportion is expected to increase continuously with the development of technology, “in view of the diversity of species, the application of the results of cloning technology research conducted by non-human organisms to humans themselves does not ensure safetyâ€. In spite of this, only technically, the continuous accumulation of scientific research has always approached the day of success of a clone. People may feel uneasy about the fact that clones may one day die. To be precise, this is a fear that the abuse of cloning technology may harm humanity itself. At the meeting, experts arguing around the issue of dividing the exclusion zone in cloning research. The core may not be in the process of cloning technology. What steps must be taken to stop it, but apply various clones now and in the future. When making technical research results, where should be clearly marked "minefield" brand. As Ms. Boerman, Minister of Education and Research of Germany, addressed the opening ceremony of the meeting, "The current definition of different research methods and targets for cloning technology is not yet clear." Between reproductive cloning research and medical cloning research It is difficult to define the relationship between the two countries. I am afraid it is the most troublesome problem for the experts. For the purpose of healing the disease, human embryos were cloned, and for the purpose of reproduction, the cloned embryos eventually became a descendant's life. The two were separated by a thin piece of paper. The panic caused by clones, such as the extinction of species, the revival of historical figures, etc., due to ignorance, gradually faded. The unresolved ethical and moral shocks have also made it difficult to build a roadblock that prevents clones from coming out. In this context, politicians are eagerly looking forward to the adoption of legislation to regulate the research and development of cloning technology. However, even if global legislation prohibits cloning research, it is difficult to ensure that the “scientific madman†without paranoia continues to try. Cloning technology is not the first or the last technology that puts human beings in an awkward position. The scientific and technological research conducted by humans is ultimately for the benefit of mankind. In the process of the development of science and technology, mankind needs to constantly correct the direction of technological development and amend the scope of application of scientific and technological achievements so that science and technology development does not deviate from the original intention of benefiting mankind.
