Human Cloning?

Although the possibility of cloning human beings has been the subject of speculation for much of the twentieth century, scientitists and policy makers began to take the prospect seriously in the 1960s. Nobel Prize winning geneticist Josuha Ledesber g advocated for cloning and genetic engineering in a seminal article in the American Naturalist in 1966 and again, the following year, in the Washington Post. He sparked a debate with conservative bioethicist Leon Kss, who wrote at the time that "the programmed reproduction of man will, in fact, dehumanize him." Another Nobel Laureate, Jmes Watson, publicized the potential and the perils of cloning in his Atlantic Monthly essay, "Moving Toward the Clonal Man", in 1971.
Scientists can now clone animals like sheep,cows,pigs,cats or horses and it is tecnally possible to clone people.
