一个基于广义信息熵的生物演化模型
evolution model of life on generalized information
生命的起源、生命的本质、生物进化的动力、生物惊人的复杂性等都是几千年来困惑人类心智的问题。科学史上的大部分时间人们都是从机械物质的角度对生命进行研究，没法揭示生物的有机性；近年来，热力学、系统科学、非线性科学、自组织理论、复杂性科学等学科群强调了有机整体性，被广泛引入到生命的研究中，但它们的思维逻辑仍是基于机械物质，仅在被隔离的物质基础上通过假设组元的相互作用来研究生命。这实际上相当于先肢解了有机生命系统，后又试图复原，这样显然会在有机生命的本质理解上不时地陷入困境。本文指出观察者与被观察对象独立开来，用隔离的物质作为生命的本原或对象是有问题的。生命是在无限联系的无边界网络中、力所能及地考虑所有联系（进而形成信息）并让其最大化而涌现出的"对象"。这样观察者与被观察对象是不可分离的，都融于"对象"之中，对象自行出现、进化并反过来认识对象本身，完成一个自足自恰的循环。本文以这样界定的对象作为生命的本原，从一开始就把生命看成是一个有机的整体，是不能被分割的，是和环境融合在一起的。进而运用最大信息熵原理或最大流原理，从信息的角度重新诠释生命，提出生命演化的基本法则，给出了关于生命演化的动力学方程，探讨了生命的本质，形成了研究生命演化的新理论框架。以此为基础，对生命的起源、生命的本质、生物进化的动力、生物的复杂性等疑难问题进行了分析。最后通过实际案例讨论了本理论框架的简单应用。
he origination of life, the essence of life, the driving force of biological evolution and the amazing complexity of living beings have been confusing the human beings for several thousands of yeas. People who investigate life from the perspective of mechanism and substance can not reveal the organic creature. In recent years, thermodynamics, system science, nonlinear science, self-organization theory and other disciplines which emphasize an organic whole are widely used to make research on life. While their logical thinking are still from the perspective of mechanism and substance. They make hypothesis on interaction of components the basis of mechanism and substance. Actually, they want to recover the organic life system after dismembering it. Obviously, they must have trouble in understanding the essence of organic life. They divide the observer and the object which is observed. They also make the divided substance as the source of life. We say they did wrong. Life is the object which springs up by considering all the interaction (causing information) been maximized in the limitless networks of infinite links. So the observer and the object which is observed can not be divided. They are both immersed in the object. The object appears by itself then they get to know itself after evolution. We see they finish the self-sufficiency and self-modify circulation. This paper we confine the object like this as the source of life. We see life as an organic unity which can not be divided and is immersed in the environment from the beginning. We interpret life from the perspective of information by maximum flux principle. Then we raise the essential law and dynamical equation of life evolution. We investigate the essence of life and create a new theory frame of life evolution. We also do analysis on the origination of life, the essence of life, the driving force of biological evolution and the amazing complexity of living beings. Finally, we discuss the simple application of this new theory frame by a practical case.
