共同进化的相互作用取决于每个物种的性状的表型界面，介导个体之间相互作用的结果。这些表型界面通常涉及性能性状，例如运动或对毒素的抗性，其包括一套完整的生理、形态和行为性状。从物种相互作用的相互选择可能会直接作用于性能，但它最终是这些潜在的组件，形状的共同进化适应的模式在性能的演变。因此，将共同进化的宏观进化模式与构建它们的生态过程联系起来，需要一种方法来剖析共同进化的表型界面，并确定一个物种的特定性能组件如何对第二个物种的互补性能组件进行选择。我们提出了一种方法，用于分析选择的强度在一个共同进化的相互作用，个人在随机的相互作用，并确定哪些组件性状的表型接口是至关重要的介导共同进化。该方法说明了从束带蛇和蝾螈之间的捕食者-猎物军备竞赛，通过河豚毒素（TTX）和它的阻力接口操作的数据。
Coevolutionary interactions depend upon a phenotypic interface of traits in each species that mediate the outcome of interactions among individuals. These phenotypic interfaces usually involve performance traits, such as locomotion or resistance to toxins, that comprise an integrated suite of physiological, morphological and behavioral traits. The reciprocal selection from species interactions may act directly on performance, but it is ultimately the evolution of these underlying components that shape the patterns of coevolutionary adaptation in performance. Bridging the macroevolutionary patterns of coevolution to the ecological processes that build them therefore requires a way to dissect the phenotypic interface of coevolution and determine how specific components of performance in one species exert selection on complimentary components of performance in a second species. We present an approach for analyzing the strength of selection in a coevolutionary interaction where individuals interact at random, and for identifying which component traits of the phenotypic interface are critical to mediating coevolution. The approach is illustrated with data from a predator-prey arms race between garter snakes and newts that operates through the interface of tetrodotoxin (TTX) and resistance to it.
