种群的可塑性是否会随着当地条件的变化而进化？Zhen等人利用喀麦隆的双翅蝶种群解决了这个问题。研究结果表明，这些非洲蝴蝶的局部适应涉及到可塑性程度的变化，因此，在季节波动较大的栖息地中，发现种群对温度的反应更强。有趣的是，尽管种群之间的基因流动水平很高，但反应规范的分化仍然存在，这表明少数基因座导致了可塑性的进化差异。
Can changes in plasticity evolve in populations in response to local conditions? Zhen et al. addressed this question using populations ofBicyclusbutterflies from Cameroon. The results of the study suggest that local adaptation in these African butterflies involved changes in the degree of plasticity, such that stronger responses to temperature were found in populations from habitats with stronger seasonal fluctuations. Interestingly, differentiation in reaction norms occurred despite high levels of gene flow among populations, indicating a small number of loci contributing to evolved differences in plasticity.
