共同进化，即两个或更多个类群之间的相互适应，通常被认为是导致地球上大部分生物多样性产生的主要机制。这一概念上吸引人的假说在进化范围内令人难以置信地广泛，涵盖了从微生物世代到地质时代的各种模式和过程。然而，令人惊讶的是，我们几乎没有证据表明共同进化和多样性之间的大规模关联在较小的时间尺度上反映了因果关系，在这种情况下，共同进化选择直接负责新物种的形成。在这一合成中，我们批判性地评估了经常被引用的假设的证据，即共同进化是促进生物多样性的重要过程。我们的结论是，缺乏共同进化多样化的广泛证据可能最好地解释了这样一个事实，即共同进化在多样化中的重要性取决于相互作用的类型和所考虑的多样化的规模。
Coevolution, reciprocal adaptation between two or more taxa, is commonly invoked as a primary mechanism responsible for generating much of Earth's biodiversity. This conceptually appealing hypothesis is incredibly broad in evolutionary scope, encompassing diverse patterns and processes operating over timescales ranging from microbial generations to geological eras. However, we have surprisingly little evidence that large-scale associations between coevolution and diversity reflect a causal relationship at smaller timescales, in which coevolutionary selection is directly responsible for the formation of new species. In this synthesis, we critically evaluate evidence for the often-invoked hypothesis that coevolution is an important process promoting biological diversification. We conclude that the lack of widespread evidence for coevolutionary diversification may be best explained by the fact that coevolution's importance in diversification varies depending on the type of interaction and the scale of the diversification under consideration.
