Humans can be cloned, but only theoretically. Scientists have cloned a sheep successfully, but it did not work well (the sheep died young) and there were many failed attempts. Many scientists and physicians are skeptically about cloning humans, due to the inefficiency of animal cloning (only about 1 or 2 viable offspring for every 100 experiments) and the lack of understanding about reproductive cloning. While humans are more complicated than sheep, they are not much more complicated, therefore, the same problems would be expected in human cloning. The big question mark will be around for a long time because cloning a person is very, very morally complicated.
