从有关进化约束的著作数量来看，它们是进化生物学中的一个重要话题。然而，它们在形成从形态停滞到适应性辐射的进化变化模式方面的参与仍然存在争议。这至少在一定程度上是因为缺乏对约束的潜在例子的强有力的分析，无论是更绝对的还是相对的。在这里，我们认为，为了探索从表型变异产生的方式中可能出现的对进化变化的约束和偏见的类型，需要应用于可以在生物组织的不同水平上解决的系统的综合方法。这一点是通过对蝴蝶翅膀眼点模式进化的研究来说明的，该研究将进化遗传学和Evo-Devo结合应用于一个新兴的模式物种，并开始采用比较方法来描述两个物种丰富的属的现有分类群之间的变异模式。
Judging by the volume of writings about evolutionary constraints, they are an important topic in evolutionary biology. However, their involvement in shaping patterns of evolutionary change from morphological stasis to adaptive radiation remains contentious. This is at least in part because of the paucity of robust analyses of potential examples of constraints, whether of a more absolute or a relative nature. Here, we argue that what is needed to explore the type of constraints and bias on evolutionary change that may emerge from the way in which phenotypic variation is generated is an integrative approach applied to systems that can be tackled at different levels of biological organization. This is illustrated using research on the evolution of patterns in butterfly wing eyespots that has applied a combination of evolutionary genetics and evo-devo to an emerging model species with the beginnings of a comparative approach to describe patterns of variability among the extant taxa of two species-rich genera.
