关于生命起源的研究，一直存在着一个严重的困境，或者说是一个鸡和蛋的悖论，进化是如何从随机反应的化学汤开始的。事实上，没有进化过程，就不可能出现像自我复制聚合物这样的进化单元，而没有进化单元，进化过程就不会开始。生命的起源和进化过程可以被认为是最初的非生命实体的持续复杂化，导致高度复杂的生命有机体。一个自我复制聚合物的概念不能单独攻击上述困境，因为它不能连接不同层次的层次结构，因此没有复合出现。本文认为，自我复制的单位可能不是生命起源的原因，而可能是不同动力学过程的结果。这是一个新的范式“内-外（或自我-非自我）循环”，被引入来解释这种动力学过程。
(Abstract) Concerning the studies of life’s origin, there has been a serious dilemma or a chicken-and-egg paradox how does evolution starts out of randomly reacting chemical soup. Actually, evolving units such as self-replicating polymers could not arise without evolving processes, whereas evolving processes would not begin without evolving units. The processes of life’s origin and its evolution can be considered as the continuous complexation of initially nonliving entities leading to highly complex living organisms. A concept of self-replicating polymers alone can not attack the above-mentioned dilemma, because it can not link different levels of the hierarchy and hence no complexation appears. The present paper assumes that self-replicating units may not be the cause of life’s origin, but instead it may be the result emerging from quite different dynamical processes. It is a new paradigm of ‘endo-exo (or self-nonself) circulation’ that was introduced to account for such dynamical processes.
