Madin et al. (Reports, 12 May 2006, p. 897) reported that escalation has not been an important cause of biological change throughout the history of life. However, they evaluated the escalation hypothesis with inappropriate data. First, global-scale data integrate heterogeneous signals that obscure the economic context of life. Second, diversity data cannot yield information about selection and adaptation.
麦丁等人（《报告》，2006年5月12日，第897页）报告称，在生命史上，进化升级并非生物变化的重要原因。然而，他们用不恰当的数据评估了进化升级假说。首先，全球范围的数据整合了不同的信号，这些信号掩盖了生命的经济背景。其次，多样性数据无法提供有关选择和适应的信息。
