The reason contain life science itself and ethics norm about it. Life science makes ethics changes. Basic dynamic is the contradiction between the progress of life science and the demand to bring benefit to human. palingenesis between new and past is the course of the change. Balance between dynamic state development and quiet state restrict is the result.

生命科学发展引起了伦理道德的变化，这一变化的根本动因是由生命科学发展与造福人类需要的矛盾决定的，而伦理道德的旧中鼎新，新中继旧则是变化的必然过程，其结果导致了动态发展与静态制约的平衡，变化的最终方向是促进生命科学更好的造福人类、提高生命质量。
