That disclaimer didn't satisfy critics. Indeed, the Korean breakthrough adds fuel to two different ethical debates at once. The first--whether cloning for reproduction should be allowed--is pretty well settled. Only a handful of loose-cannon scientists and members of the Raelian sect, who believe humans were created...
