提出了一个模型来表达动物如何有效地通过咀嚼来增加食物的暴露表面积。它包括咀嚼有效性系数（E），其值随着每次咀嚼暴露新食物表面积的有效性而增加。人类和其他灵长类动物的E值有显著差异;在非人类灵长类动物的研究中，猫狐猴的系数高于黄狐猴，两者的系数都高于Varecia variegatus或Galago crassicaudatus argentatus。这些原猴的系数之间的差异与摩尔形态的具体特征的变化相关。
A model is presented to express how effectively animals increase the exposed surface area of their food by chewing. It includes a coefficient of masticatory effectiveness (E) the value of which increases with effectiveness of exposing new food surface area with each chew. Humans and other species of primates differ significantly in their values of E; among the nonhuman primates studies, Lemur catta has a higher coefficient than Lemur fulvus, and both have higher coefficients than either Varecia variegatus or Galago crassicaudatus argentatus. The differences among the coefficients to these prosimians are correlated with variations in specific features of the molar morphology.
