动物行为学将行为模式定义为相对不变的、物种特有的运动模式。动作模式被认为具有物种特异性的形式特征，就像解剖形态学包含物种特异性的形式特征一样。然而，形态存在于空间中，而运动则在时间中形成。因此，运动和形态不能以相同的方式量化。量化动物运动的空间和时间维度的标准方法不适合于统计学，跨物种的比较研究。本文介绍了一种方法，定量咀嚼下颌运动，以便严格的跨物种比较可以。结果表明，下颌运动包含物种特异性的功能，其中许多是视觉上无法检测。结果表明，它是可能的解释的动作模式定义字面上的咀嚼颌骨运动有一个可量化的形式，其中包含物种特异性的功能。此外，研究结果表明，下颌运动的形式似乎反映了动物的系统发育历史，以及目前的摄食生态位。未来的研究应该能够阐明牙体发育和饮食选择的压力如何相互作用，以产生特定的功能，牙骨形态和咀嚼运动的形式。
Ethology defines action patterns as relatively invariant, species-specific movement patterns. Action patterns are said to have species-specific form features, much like anatomical morphology contains species-specific form features. However, morphology exists in space, whereas movements take form in time. Thus, movements and morphology cannot be quantified in the same way. Standard methods of quantifying the spatial and temporal dimensions of animal movements are not amenable to statistical, cross-species comparative studies. This paper describes a method of quantifying masticatory jaw movements so that rigorous cross-species comparisons can be made. Results show that jaw movements contain species-specific features, many of which are not visually detectable. The results suggest that it is possible to interpret the action pattern definition literally in that masticatory jaw movements have a quantifiable form, which contains species-specific features. Furthermore, the results show that jaw movement forms appear to reflect an animal's phylogenetic history as well as its current feeding niche. Future investigations should be able to elucidate how phylogeny and dietary selection pressures interact to produce specific features of dentoskeletal morphology and masticatory movement form.
