生物表型进化与分子进化的联系和差异

On Relationship and Difference between the Phenotype and Molecular Evolution of Living Things

在物种的系统演化中 ,自然选择学说和分子进化学说分别着眼于表型层次和分子层次的进化机制 ,自然选择学说从群体水平上阐明了生物进化的规律 ,而中性学说则揭示了生物在分子水平的进化不同于表型水平的进化 .笔者旨在阐述生物表型适应进化与分子中性进化在不同层次上所揭示的生物进化的机制和规律 .

Among the systematic species,the hypothensis of both natural selection and the molecular evolution individually details the machanism of the phenotype structure and the molecular structure. The theory for natural selection expounds the laws of the evolution of living things at colony levels, but the hypothensis of neutral evolution gives the opinion that the evolution of living things at the molecular levels goes differently from that at the phenotype ones. This paper is just going into the details about the opinion.
