许多关于共同进化的研究都集中在物种间相互作用所导致的适应上。为了发生互惠进化，每个物种中必须存在直接影响它们相互作用的特征的遗传变异。在这里，我报告了寄生黄蜂种群在成功寄生蚜虫宿主的能力方面存在显着加性遗传差异的证据。这些数据，再加上记录同一地点的一群蚜虫的克隆变异的配套工作，提供了证据，证明在同一种群内，寄主和它的寄生蜂都有可能进行特定和互惠的遗传相互作用。
Much of the study of coevolution has focused on the adaptations that have resulted from interactions between species. For reciprocal evolution to occur, there must be genetic variation in each species for traits that directly affect their interaction. Here I report evidence of significant additive genetic variance within a population of parasitic wasps in the ability to successfully parasitize an aphid host. These data, combined with companion work documenting clonal variation in a population of aphids from the same site, provide evidence that within the same population both a host and its parasitoid have the potential for specific and reciprocal genetic interactions.
