摘要
现有的对生命起源和本质的各种论述以及生命的各种定义都没有找到生命起源的充分必要条件。自然条件下能实现自复制的比较稳定的大分子物质结构才是生命产生的充分必要条件,自复制能够解决生命的复杂结构产生的概率问题。有了正反馈,进化的世界观才能成立,才能战胜热力学第二定理引导的退化的世界观。
Neither in the current theories about the origins and essence of life nor in the various definitions of life could one find out the prerequisite of the origins of life. It is the steady structure of the large molecule which can be self-reproduced under the natural condition that is the prerequisite for life. Self-reproduction deals with the issue of probability made by the complex structure of life. With positive feedback, the evolutionary outlook is available which makes it possible to fight against the retrograde outlook directed by the second theorem of thermodynamics.
