Speciation research bridges the realms of macro- and microevolution. Evolutionary developmental biology (evo-devo) has classically dealt with macroevolutionary questions through a comparative approach to distantly related organisms, but the field later broadened in focus to address recent speciation and microevolution. Here we review available evidence of the power of evo-devo approaches to understand speciation in plants at multiple scales. At a macroevolutionary scale, evidence is accumulating for evolutionary developmental mechanisms giving rise to key innovations promoting speciation. At the macro microevolution transition, we review instances of evo-devo change underlying both the origin of reproductive barriers and phenotypic changes distinguishing closely related species. At the microevolutionary scale, the study of developmental variation within species provides insight into the processes that generate the raw material for evolution and speciation. We conclude by advocating a strong interaction between developmental biology and evolutionary biology at multiple scales to gain a deeper understanding of plant speciation.
物种形成研究架起了宏观进化和微观进化领域之间的桥梁。进化发育生物学（evo-devo）传统上通过对远缘相关生物体的比较方法来处理宏观进化问题，但该领域后来将重点扩大到解决近期的物种形成和微观进化。在这里，我们回顾了进化发育生物学方法在多个尺度上理解植物物种形成的现有证据。在宏观进化尺度上，越来越多的证据表明进化发育机制会产生促进物种形成的关键创新。在宏观-微观进化过渡阶段，我们回顾了生殖隔离起源和区分近缘物种的表型变化背后的进化发育生物学变化实例。在微观进化尺度上，对物种内发育变异的研究为产生进化和物种形成原材料的过程提供了见解。我们通过倡导发育生物学和进化生物学在多个尺度上的强烈互动来得出结论，以便更深入地理解植物物种形成。
