信息与物质的相互作用

以人类语言与人脑共同进化为例，阐述了信息与物质之间可能存在的一种相互作用．阐述了为人类语言与人脑的共同进化提供证据的已有研究结果，包括人类脑皮层语言区、人类语言和人脑进化过程、人类语言进化的遗传学基础．以此为基础，建立了一个动力学模型，刻画了人类语言发展和人脑发育的相互促进过程:语言发展水平可通过语言相关的基因突变所导致的脑功能进步来提高，而突变基因能否被正向选择取决于语言发展水平，只有满足一定条件的突变基因才能被正向选择．因此，人类语言和人脑经历了一个共同进化过程，该过程为分析信息与物质的相互作用提供了一个途径． 

The interaction of information and matter: a case study about the coevolution of human language and brain

Is there any interaction between information and matter? Coevolution of human language and brain as a case of interaction between information and matter is studied．First, evidence for possible coevolution of human language and brain as revealed by previous works is discussed．These include language-related areas in human cerebral cortex, evolution of human language and brain, genetic basis of evolution of language. A dynamic model is developed to examine mutual enhancement of human language and brain．Developmental level of language can be promoted by advances in brain function due to language-related gene mutations．Whether such mutations are positively selected can be influenced by developmental levels of language．Only mutations satisfying preliminary conditions are positively selected．Coevolution of human language and brain is a special case of interaction between information and matter．
