There exists an extensive literature that deals with interspecific allometry, eg, brain size-body size relationships among species. Yet comparatively little attention has been paid to intraspecific or static adult allometry. An intraspecific allometric analysis was conducted on the complete permanent dentition of a prehistoric American Indian population (N = 156). Mesiodistal and buccolingual measurements were logarithmically transformed and regressed on log transformations of femur length, an estimate of body size. When measurements of antimeric teeth were introduced together into common regressions on femur length, 20 of the 32 slopes were significantly different from zero. Thirty-one of the slopes ranged between zero and one and clustered between 0.2 and 0.4. Hence, negative allometry describes the tooth size-body size association, ie, taller individuals in general possess absolutely but not relatively larger teeth than shorter individuals. In addition, no significant sex differences for the regression slopes were observed. Though significantly correlated, tooth size and body size variables are too weakly associated to permit accurate predictions from regression equations. Evolutionary implications of intraspecific dental allometry are discussed.
有大量文献涉及种间异速生长，例如物种间脑容量与身体大小的关系。然而，种内或静态成年异速生长受到的关注相对较少。对一个史前美洲印第安人群体（N = 156）的完整恒牙列进行了种内异速生长分析。近远中径和颊舌径测量值进行对数转换后，以股骨长度的对数转换值为自变量进行回归分析，股骨长度是身体大小的一个估计指标。当将对侧牙齿的测量值一起纳入股骨长度的共同回归分析时，32个斜率中有20个显著不同于零。其中31个斜率在零和一之间，集中在0.2到0.4之间。因此，负异速生长描述了牙齿大小与身体大小的关联，即一般来说，身材较高的个体牙齿的绝对尺寸更大，但相对尺寸并不比身材较矮的个体大。此外，未观察到回归斜率存在显著的性别差异。尽管牙齿大小和身体大小变量显著相关，但关联程度太弱，无法通过回归方程进行准确预测。文中讨论了种内牙齿异速生长的进化意义。
