| 摘 要： | 在进行生物系统发育研究的过程中,不同性质或来源的数据产生的结果之间往往存在差异,这种数据的不相合性已经成为我们重建系统发育历史的重要影响因素.本文介绍了数据不相合性存在的范围和成因,目前用于检测数据不相合性的主要方法:ILD检测,SH检测,PABA检测和PCI系数检测等,并对这些方法进行了比较,讨论了对不相合性数据的处理方法.

| Abstract: | Molecular characters provide a wealth of new information that sheds light on many parts of the 'Tree of Life'. However, phylogenetic analyses based on different data often lead to apparently conflicting results. Techniques for measuring and testing the significance of this phylogenetic incongruence is especially necessary when considering combining datasets composed of multiple data that may or may not have different histories. Here, we review the different incongruence tests and how we handle the incongruence data in phylogenetic analysis with them being used as a starting point. |
