A recent study published in by Thompson and Ramírez-Barahona (2023) argued that, according to analyses of diversification on two massive molecular phylogenies comprising thousands of species, there is no evidence that angiosperms (i.e. flowering plants) were affected by the Cretaceous-Paleogene mass extinction. Here, I critique these conclusions from both methodological and philosophical perspectives. I demonstrate that the methods used in their study possess statistical limitations that strongly reduce the power to detect a true mass extinction event using data similar to those analysed by Thompson and Ramírez-Barahona (2023). Additionally, I use their study as a springboard to examine the relationship between phylogenetic and fossil evidence in diversification studies.
汤普森和拉米雷斯-巴拉霍纳（2023 年）最近在《》杂志上发表的一项研究认为，根据对包含数千个物种的两个大规模分子系统发育分析，没有证据表明被子植物（即开花植物）受到白垩纪-古近纪大灭绝的影响。在这里，我从方法论和哲学的角度来批判这些结论。我证明了他们的研究中使用的方法存在统计学上的局限性，这大大降低了使用类似于汤普森和拉米雷斯-巴拉霍纳（2023 年）分析的数据来检测真正的大灭绝事件的能力。此外，我还利用他们的研究作为一个跳板，来研究进化研究中系统发育和化石证据之间的关系。
