During the decade, the ethics problems about scientific research are started to beconcerned. No matter the human experiment carried on in cold war period, or there searches about embryo of genetic engineering, human chromosome plan, intelligence science of heredity, even the greenhouse effects problems etc., are all to be the new focuses in modern ethics. The main cause of this change, it ‘s because once the scientific researches lack of the ethics idea, not only will threaten the result of the researches, and will also influence the security or the development of the whole society. Since the ethics conflicts not only play a important role but also appear very often, scientist cannot ignore any more. During the experiments scientists cannot just consider the value or worth of the experiment but should also think carefully about the ethics issues. Being aware of the importance of the scientific ethics, in this article, I would like to base on the Buddhist ethics to discuss the ethics conflicts which would appear in the “ clone experiment ”.
