用基因组大小进化机制对生命进行分类

Classification of life by the mechanism of genome size evolution

Dirson Jian Li, Shengli Zhang

摘要:

生命的分类应该基于生命进化的基本机制。我们发现,物种之间的全球关系应该是循环系统发育,这与基于系统发育树的常识有很大的不同。通过对当代物种蛋白质长度分布的分析,可以清楚地观察到系谱圈。因此,我们建议域可以定义为区别系统发育圈,这是全球性的和稳定的生活系统的特征。阐明了基因组大小进化的机制,从而解释了C值之谜的主要组成问题。根据蛋白质长度分布的相关性和准周期性,我们还可以将生命分为三个域。

英文摘要:

The classification of life should be based upon the fundamental mechanism in the evolution of life. We found that the global relationships among species should be circular phylogeny, which is quite different from the common sense based upon phylogenetic trees. The genealogical circles can be observed clearly according to the analysis of protein length distributions of contemporary species. Thus, we suggest that domains can be defined by distinguished phylogenetic circles, which are global and stable characteristics of living systems. The mechanism in genome size evolution has been clarified; hence main component questions on C-value enigma can be explained. According to the correlations and quasi-periodicity of protein length distributions, we can also classify life into three domains.
