Ecological interactions, such as predation and bioturbation, are thought to be fundamental determinants of macroevolutionary trends. A data set containing global occurrences of Phanerozoic fossils of benthic marine invertebrates shows escalatory trends in the relative frequency of ecological groups, such as carnivores and noncarnivorous infaunal or mobile organisms. Associations between these trends are either statistically insignificant or interpretable as preservational effects. Thus, there is no evidence that escalation drives macroecological trends at global and million-year time scales. We also find that taxonomic richness and occurrence data are cross-correlated, which justifies the traditional use of one as a proxy of the other.
生态相互作用，如捕食和生物扰动，被认为是宏观进化趋势的基本决定因素。一个包含显生宙底栖海洋无脊椎动物化石全球分布情况的数据集显示，食肉动物和非食肉的底内动物或活动生物等生态类群的相对频率呈上升趋势。这些趋势之间的关联要么在统计上不显著，要么可解释为保存效应。因此，没有证据表明在全球和百万年时间尺度上，进化升级驱动了宏观生态趋势。我们还发现分类丰富度和出现数据是相互关联的，这证明了传统上用一个作为另一个的替代指标是合理的。
