Although we may someday in the technical aspects be able to accomplish this task. The question still remains whether or not we should. Ethics and morality can not be separated from science because it is the only thing that prevents humans from destroying ourselves. I think that ethics is linked to science in such a way that they could never be divided. Ethics acts as a set of ever changing rules that govern what is allowed in science.
Ethics helps to keep our knowlege in check and used solely for our betterment as a world.
Dr. Richard Seed is a perfect example of science going off half-cocked. Although the cloning of humans may eventually be a reality the morality of the action must be taken into account and the needs of the people must be paramount to the action. The basis for the scientific study is the quest for knowledge. Science itself is neutral, however new technologies are not always used in ethical ways. It is only those that pay for it that decide what ethical ramifications will come from new discoveries.
