当相互作用的个体的健身兴趣不同时，进化冲突就会出现。众所周知的例子包括雄性和雌性之间的性冲突以及宿主和寄生虫之间的对抗性共同进化。这种冲突的一个共同特征是，每一方的补偿性进化变化可能导致互动本身几乎没有明显的变化。因此，即使各方之间的进化动态达到平衡，进化冲突预计也会持续下去。在这些情况下，了解在这种进化僵局中，某些类型的相互作用是否会导致更大或更小的进化冲突是很有意义的。在这里，我们提出了一个理论分析表明，当相互作用的一方可以通过适应性表型可塑性，进化冲突减少。然而，具有讽刺意味的是，没有表现出适应性可塑性的一方经历的冲突较少。冲突的一方显示适应性可塑性可以增加或减少，这取决于情况。
Evolutionary conflicts arise when the fitness interests of interacting individuals differ. Well-known examples include sexual conflict between males and females and antagonistic coevolution between hosts and parasites. A common feature of such conflicts is that compensating evolutionary change in each of the parties can lead to little overt change in the interaction itself. As a result, evolutionary conflict is expected to persist even if the evolutionary dynamic between the parties reaches an equilibrium. In these cases, it is of interest to know whether certain kinds of interactions are expected to lead to greater or lesser evolutionary conflict at such evolutionary stalemates. Here we present a theoretical analysis showing that when one of the interacting parties can respond to the other through adaptive phenotypic plasticity, evolutionary conflict is reduced. Paradoxically, however, it is the party that does not express adaptive plasticity that experiences less conflict. Conflict for the party displaying adaptive plasticity can increase or decrease, depending on the situation.
