This breakthrough possibly enabled people to bring their adored pets back to life. However, it bothered him from time to time that their health was in poor condition because they were unable to resist illnesses. This drawback cast him down. Merely 2 weeks later, the clones and their carrier died, which struck frustration into his heart. He retired before he attained his ambition and became a member of an opera chorus to relieve his depression.Shortly afterwards, the media published a conservative argument objecting to cloning owing to moral problems, and suggested the constitution include compulsory regulations to forbid obtaining commercial profits from cloning.When interviewed, the scientist stared at the decorations on the ceiling, thinking for a while, and then said, “I’m not in favour of any arbitrary assumption, but undertaking cloning does differ from the straightforward procedure of making loafs out of flour. Until we accumulate enough exact knowledge, any practice is in vain and is bound to fail. Altogether, being more careful is reasonable or we may walk into a side road.”谨慎对待克隆在最初一系列的实验和修正之后，科学家的辛苦工作终于取得了成功，一对双生的克隆火鸡孵化出来，羽毛和爪子都很正常。
