在现代分子进化研究中,根据现有生物基因或物种多样性来重建生物的进化史是一个非常重要的问题。一个可靠的系统发生的推断,将揭示出有关生物进化过程的顺序,有助于我们了解生物进化的历史和进化机制。本文简要介绍了系统发生树推断的几个重要问题:建树方法、数据转换、树的可靠性及目前使用较多的几种分析软件。

Reconstruction of the evolutionary history of species based on the genetic and species diversity is one of the most important subjects in the current study of molecular evolution. If reliable phylogenies are produced , they will shed light on the sequence of evolutionary events , and help us to understand the mechanisms of evolution as well as the history of organisms. The goal in this paper is to give a brief introduction to several important issue in phylogeny inferring : the tree-building methods , data transformation , reliability of inferred tree , and several common used computer programs.
