There are increasing calls to incorporate developmental plasticity into the framework of eco-evolutionary dynamics. The current way is via genotype-specified reaction norms in which inheritance and phenotype expression are gene-based. I propose a developmental system perspective in which phenotypes are formed during individual development in a process comprising a complex set of interactions that involve genes, biochemistry, somatic state, and the (a)biotic environment, and where the developmental system is the unit of phenotype evolution. I explain how the two perspectives differ in assumptions and predictions, which can be contrasted using cue-and-response systems of anticipatory or mitigating developmental plasticity. This can lead to new ways of eco-evolutionary thinking, and deliver important explanations of how populations respond to environmental change through evolved developmental plasticity.
人们越来越呼吁将发育可塑性纳入生态进化动力学的框架中。目前的方法是通过基因型指定的反应规范,其中遗传和表型表达是基于基因的。我提出了一个发育系统的观点,在这个观点中,表型是在个体发育过程中形成的,这个过程包括一系列复杂的相互作用,涉及基因、生物化学、体细胞状态和(非生物)环境,而发育系统是表型进化的单位。我解释了这两种观点在假设和预测上的差异,可以使用预期或缓解发育可塑性的提示-反应系统进行对比。这可以带来新的生态进化思维方式,并提供关于种群如何通过进化发育可塑性对环境变化做出反应的重要解释。
