Yeraldi breaks down rapid evolution of thermal plasticity in city lizards for Kristin's blog "Life in the City"
““The importance of plasticity in the colonization of new environments is a widely-accepted argument, however, the role of plasticity in facilitating adaptive evolution remains controversial. Plasticity may facilitate novel habitat colonization via phenotypic expression that results in high fitness without the action of natural selection (i.e., “perfect plasticity”), or alternatively plasticity may be insufficient and natural selection may act to further modify the phenotype towards an adaptive optimum (i.e., “evolved plasticity”).””
