Until recently, there were few ethical, social, or legal discussions about human cloning via nuclear transplantation, since the scientific consensus was that such a procedure was not biologically possible. With the appearance of Dolly, the situation has changed yet has changed in a way to oppose human cloning. Although it now seems more likely that human cloning will become feasible, we may doubt that the practice will come into widespread use because of the pros of cloning shown above let alone the ethical argument against cloning. While the technology for nuclear transplantation advances, other technologies -- notably the technology of genetic engineering -- will be progressing as well and will be more acceptable because of ethics. Human genetic engineering will be applicable to a wide variety of traits; it will be more powerful than cloning, and hence more attractive to more people around the world. Yet just like cloning it will also raise more troubling questions and will incur similar arguments against it.
