Abstract

Harish and Kurland recently compared two evolutionary models that root the tree of life. Both models make use of unordered phylogenetic characters. Here we show that they confused one of their models with models that use Wagner ordered characters. In addition, we also show that these Wagner characters should be polarized a posteriori with the generality criterion and not with external outgroup hypotheses. These facts question the rationale of their comparative phylogenomic exercise.

摘要

哈里什和库尔兰最近比较了两种构建生命之树的进化模型。这两种模型都使用了无序的系统发育特征。在这里，我们表明他们将其中一个模型与使用 Wagner 有序特征的模型混淆了。此外，我们还表明，这些 Wagner 特征应该使用普遍性标准进行后验极化，而不是使用外部外群假设。这些事实质疑了他们比较基因组学研究的基本原理。
