克尔斯肯等人。 (Hydrobiologia 811:283-293, 2018) 最近报道了玻璃海绵（Porifera：Hexactinellida）核糖体 DNA 的系统发育分析，包括来自东北太平洋的新标本。他们的研究很重要，因为它显着增加了这一重要深海群体的分类单元采样。不幸的是，这些作者的数据集组装和系统发育分析方法的选择存在一些问题。此外，他们没有考虑与他们的结果解释高度相关的先前文献。在这里，我对他们的论文提供了批判性的建设性评论，并提出了利用既定方法论技术的替代分析。我表明 Kersken 等人的一些发现和主张是不可持续的，并对更新的玻璃海绵系统发育进行了扩展讨论。
Kersken et al. (Hydrobiologia 811:283-293, 2018) recently reported a phylogenetic analysis of ribosomal DNA of glass sponges (Porifera: Hexactinellida) including new specimens from the NE Pacific. Their study is important as it significantly increased the taxon sampling of this important deep-sea group. Unfortunately, there are several issues with these authors' dataset assembly and choice of phylogenetic analysis methods. Furthermore, they did not consider previous literature that is highly relevant to interpretation of their results. Here I provide critically constructive comments on their paper and present an alternative analysis that utilizes established methodological techniques. I show that several of Kersken et al.'s findings and claims are unsustainable, and provide an extended discussion of the updated glass sponge phylogeny.
