10多年来，系统分类学家一直在争论性状一致性或分类一致性在系统发育分析中的优越性。在本文中，我们证明了竞争的方法可以收敛到相同的解决方案时，一个共识的方法，占分支长度被选中。因此，我们建议结合使用这两种方法，作为一种方法来证实合并和单独分析的结果。这种所谓的“全球一致性”的方法进行了测试，从文献中采样的各种各样的例子，并与标准的共识方法所获得的结果进行比较。我们的分析表明，当总证据和共识树在拓扑上不同时，折叠具有低引导支持度的弱支持节点通常会提高“全局一致性”。
For more than 10 years, systematists have been debating the superiority of character or taxonomic congruence in phylogenetic analysis. In this paper, we demonstrate that the competing approaches can converge to the same solution when a consensus method that accounts for branch lengths is selected. Thus, we propose to use both methods in combination, as a way to corroborate the results of combined and separate analyses. This so-called "global congruence" approach is tested with a wide variety of examples sampled from the literature, and the results are compared with those obtained by standard consensus methods. Our analyses show that when the total evidence and consensus trees differ topologically, collapsing weakly supported nodes with low bootstrap support usually improves "global congruence".
