It is unclear why a "strict ban on human cloning" is needed. The article quotes researcher Lewin: "“We now understand why clones fail, which can lead to improvements in the process of cloning of animals. Our discoveries also reinforce the need for a strict ban on human cloning for any purposes.” A quick read of the article itself suggests the it does no consider human cloning and does not provide support for the conclusion that a "strict ban on human cloning" is needed. But the reasoning behind the "need" is never explained. I suspect that the need for a strict ban comes from the bioethics folks and is not a real need.
