Many nations outlawed it, while a few scientists promised to make a clone within the next few years. With the cloning of a sheep known as Dolly in 1996 by somatic cell nuclear transfer (SCNT), the idea of human cloning became a hot debate topic. Watson, publicized the potential and the perils of cloning in his Atlantic Monthly essay, "Moving Toward the Clonal Man", in 1971. He sparked a debate with conservative bioethicist Leon Kass, who wrote at the time that "the programmed reproduction of man will, in fact, dehumanize him." Another Nobel Laureate, James D. Nobel Prize-winning geneticist Joshua Lederberg advocated cloning and genetic engineering in an article in The American Naturalist in 1966 and again, the following year, in The Washington Post. They would be made from people who were held to have excelled in a socially acceptable accomplishment. Perhaps the first step will be the production of a clone from a single fertilized egg, as in Brave New World.Īssuming that cloning is possible, I expect that most clones would be made from people aged at least fifty, except for athletes and dancers, who would be cloned younger. It is extremely hopeful that some human cell lines can be grown on a medium of precisely known chemical composition. In his speech on "Biological Possibilities for the Human Species of the Next Ten Thousand Years" at the Ciba Foundation Symposium on Man and his Future in 1963, he said: Haldane was the first to introduce the idea of human cloning, for which he used the terms "clone" and "cloning", which had been used in agriculture since the early 20th century. Reproductive cloning would involve making an entire cloned human, instead of just specific cells or tissues.Īlthough the possibility of cloning humans had been the subject of speculation for much of the 20th century, scientists and policymakers began to take the prospect seriously in 1969. Two common methods of therapeutic cloning that are being researched are somatic-cell nuclear transfer and (more recently) pluripotent stem cell induction. ![]() It is an active area of research, but is not in medical practice anywhere in the world, as of 2023. Therapeutic cloning would involve cloning cells from a human for use in medicine and transplants.
