Sporadic announcements over the past two years from a number of groups in Asia, Europe, and North America that women under their care have given birth, or are about to give birth, to a "human clone" have not only produced doubts about the credibility of such claims but have also reactivated the public debate in this area and raised questions about the facts and ethics of what might be involved in human cloning. Public attention has also been stimulated by reports from scientists in several countries that they have either succeeded in creating stem cell lines from "cloned embryos" or are planning to do so.
