As technological advancements develop, scientists begin to speculate about human cloning being realistically achieved, as this occurs, opposing groups and organizations raise their voices against it and raise the question of whether scientists should be allowed to clone humans. , the promise of cloning at any level can revolutionize the world and change it for the better, but we are not ready for human trials. If successful, cloning can lead to many positive technological advances that could help humanity. Dolly, the first cloned mammal, inspired many scientists to speculate about a new era in cloning technology and to raise hope for a future probability in which human cloning would be possible. At the center of the controversy emerges the closest thing to a clone that leads a healthy and regular life, identical twins. The promise of cloning at any level can revolutionize the world and change it for the better, but are we really ready for human trials? Human cloning is the process of producing a copy of a human being. This is the exact genetic copy and every piece of their DNA is identical. If successful, cloning can lead to many positive technological advances that could help humanity. Possible benefits would be: replacing deceased loved ones, reproducing humans with special abilities and high intelligence like Einstein and regenerative medicine. Regenerative medicine is the process of using cloned organs to replace damaged human organs. As splendid as it may seem, no clone, human or animal, has met the challenge without any complications. Like a fairy tale, cloning seems too good to be true and the failure rate is enormous. “Your success cannot be 1 or 2 percent. A 2 percent success rate is not... middle of article... is not only unfair, but also counterproductive to the development of each twin's individuation. In conclusion, the thesis of this article is supported by three assertions. First, if successful, cloning can lead to many positive technological advances that could help humanity. Second, Dolly, the first cloned mammal, inspired many scientists to speculate about a new era in cloning technology and to raise hope for a future probability in which human cloning would be possible. Finally, at the center of the controversy, emerges the closest thing to a clone that leads a healthy and regular life, identical twins. The promise of cloning at any level can revolutionize the world and change it for the better, but we are not ready for human trials. The failure rate is overwhelming; we should master animal cloning with a near 100% success rate before we begin human cloning trials.
