灵长目动物的一些行为生态学变异可以用贾曼/贝尔原理来解释。这一原理涉及新陈代谢和体型之间的比例关系，这表明体型是动物摄食策略的基本策略。根据这个模型，可以对已知体重的灵长类动物的饮食做出相对准确的预测。它可以扩展到预测动物会出现的各种适应，偏离预期的大小/饮食模式。该模型是足够普遍的，当加入喂养策略理论，它可以适用于灭绝的生物。更新世人科动物生态学的特点可能是杂食性多于食肉性。
Some of the behavioral-ecological variation in the primate order can be explained by the Jarman/Bell principle. This principle involves a scaling relationship between metabolism and body size which suggests that body size is a fundamental tactic in an animal''s feeding strategy. Relatively accurate predictions regarding the diets of primates of known body weight follow from this model. It can be expanded to predict the kinds of adaptations that would appear in animals that deviate from the expected size/diet pattern. The model is general enough such that, when joined with feeding strategy theory, it can be applied to extinct organisms. Pleistocene hominid ecology was probably characterized more by omnivory than carnivory.
