Competing phylogenetic hypotheses have become the rule in modern systematics. While the problem of incongruence between character sets has become extremely acute due to the generation of molecular data, it is by no means specific to molecular and morphological comparisons. The role of the modern systematist is to interpret incongruence between character sets and to come to some conclusion regarding a phylogenetic hypothesis of the organisms in question. Two aspects of congruence analysis are examined using the Drosophilidae as an example. The first includes the quantification of congruence and the types of phylogenetic inference that can be made from such analyses. The second aspect concerns an examination of character evolution in order to identify characters and taxa that might be contributing to incongruence in phylogenetic analysis.
相互竞争的系统发育假说已成为现代系统分类学的常态。由于分子数据的产生，性状集之间的不一致问题变得极为尖锐，但这绝非分子与形态学比较所特有。现代系统分类学家的职责是解读性状集之间的不一致，并就相关生物的系统发育假说得出某种结论。本文以果蝇科为例，探讨了一致性分析的两个方面。第一个方面包括一致性的量化以及可从此类分析中得出的系统发育推断类型。第二个方面涉及对性状进化的考察，以识别可能导致系统发育分析中出现不一致的性状和分类单元。
