Vertebrates interact directly with food items through their dentition, and these interactions with trophic resources could often feedback to influence tooth structure. Although dentitions are often considered to be a fixed phenotype, there is the potential for environmentally induced phenotypic plasticity in teeth to extensively influence their diversity. Here, we review the literature concerning phenotypic plasticity of vertebrate teeth. Even though only a few taxonomically disparate studies have focused on phenotypic plasticity in teeth, there are a number of ways teeth can change their size, shape, or patterns of replacement as a response to the environment. Elucidating the underlying physiological, developmental, and genetic mechanisms that generate phenotypic plasticity can clarify its potential role in the evolution of dental phenotypes.

脊椎动物牙列的表型可塑性

脊椎动物通过它们的牙列直接与食物相互作用，这些与营养资源的相互作用通常可以反馈以影响牙齿结构。尽管牙列通常被认为是固定的表型，但牙齿中环境诱导的表型可塑性有可能广泛影响其多样性。在这里，我们回顾了有关脊椎动物牙齿表型可塑性的文献。尽管只有少数分类学上不同的研究关注牙齿的表型可塑性，但牙齿可以通过多种方式改变其大小、形状或替换模式，以响应环境。阐明产生表型可塑性的潜在生理、发育和遗传机制可以阐明其在牙齿表型进化中的潜在作用。
