The analysis of Madin et al. (Reports, 12 May 2006, p. 897) of Phanerozoic diversity failed to support expected correlations between carnivores and noncarnivores, leading the authors to reject escalation as an important macroevolutionary process. The test, however, is based on a flawed model of causality, and the ecological groups are improperly delineated with regard to the hypothesis.
马丹等人（《报告》，2006年5月12日，第897页）对显生宙生物多样性的分析未能支持食肉动物与非食肉动物之间的预期关联，导致作者拒绝将进化升级视为一个重要的宏观进化过程。然而，该检验基于一个有缺陷的因果模型，并且就该假设而言，生态群体的划分并不恰当。
