As various newspaper articles, books, and movies suggest, the cloning of human beings— producing new individuals from activated somatic cells, perhaps followed by uterine implant—is now possible. Can you suggest any biological advantages or disadvantages to having the earth populated with clones of a few of the best examples of our species?
What will be an ideal response?
This is a serious ethical
question and would require a lengthy answer. In simple terms, advantages would be that
the human race would be healthier, stronger and possibly more intelligent. Disadvantages
would be a lack of genetic diversity within the human race and the removal of people's free
will to reproduce. Of course, other answers are also possible.
