我们认为，发育激素通过遗传调节促进了新的表型创新的进化和生活史事件的计时。在个体的生命周期中，变态荷尔蒙很容易对环境条件做出反应，并改变成体的表型。在几代人之间，激素的许多影响可能会在变态过程中偏向并有时限制特征的进化；然而，激素系统可以通过改变内分泌调节的时机和获得组织对内分泌调节的特定反应来克服限制。由于激素的这些作用，变质激素可以塑造变质生物体的进化。我们提出了一个名为发育高脚杯的模型，它提供了变质有机体可能如何进化的直观表示。此外，由于发育激素通常对环境变化做出反应，我们讨论了胚胎后发育的内分泌调节可能如何影响生物体如何进化以响应气候变化。因此，我们认为发育激素可能在气候变化和生物适应之间提供了一种机制联系。
We argue that developmental hormones facilitate the evolution of novel phenotypic innovations and timing of life history events by genetic accommodation. Within an individual’s life cycle, metamorphic hormones respond readily to environmental conditions and alter adult phenotypes. Across generations, the many effects of hormones can bias and at times constrain the evolution of traits during metamorphosis; yet, hormonal systems can overcome constraints through shifts in timing of, and acquisition of tissue specific responses to, endocrine regulation. Because of these actions of hormones, metamorphic hormones can shape the evolution of metamorphic organisms. We present a model called a developmental goblet, which provides a visual representation of how metamorphic organisms might evolve. In addition, because developmental hormones often respond to environmental changes, we discuss how endocrine regulation of postembryonic development may impact how organisms evolve in response to climate change. Thus, we propose that developmental hormones may provide a mechanistic link between climate change and organismal adaptation.
