Cloning a human could be beneficial if the cloning produces useful stem cells for the treatment of disease in humans, but cloning could be ethically inappropriate and open up new challenges both ethically and legally, according to How Stuff Works.
The first successful cloning yielded a sheep named Dolly and was performed by a Scottish scientist in July of 1996. There has been no human clone documented to date, and the debate over its positive and negative aspects rages on. If human cloning were to be successful, science in medicine would find more options for helping those in need with the use of stem cells This could change the way that many find treatment. There would need to be much work done to create a human clone, considering it took scientists 277 failed attempts to develop a success in Dolly. The process of cloning a human involves taking one cell from a human that has DNA within it and fusing it with an enucleated egg (an egg without a nucleus) using electricity. In doing this, an exact duplicate would be created, unlike having offspring. Many wonder what ethical boundaries would be overstepped in order to accomplish this goal, why it should be considered and what the world might be like with clones adding to the population.
