Interspecific differences in craniodental morphology among Pan paniscus, Pan troglodytes, and Gorilla gorilla are analyzed. These apes differ in both diet and body size, and thus present an excellent example in which to apply an allometric criterion of subtraction in order to determine morphological differences which might be related to divergent dietary specialization. The use of ontogenetic allometry in particular as a criterion of subtraction is discussed. Bivariate and multivariate results indicate that most of the variation in skull form among the species relates to the extension of a common growth trend to different sizes. Comparative analysis of growth trajectories reveals a number of differences, but none that appear to relate to a reorganization of skull proportions which might correspond to a dietary shift towards increased folivory. The dentition clearly exhibits non-allometric shape changes corresponding to the dietary differences, however. The meaning of these differences between cranial and dental patterns is discussed.
对倭黑猩猩、黑猩猩和大猩猩之间颅齿形态的种间差异进行了分析。这些猿类在饮食和体型上都有所不同，因此提供了一个很好的例子，可应用异速生长减法标准来确定可能与不同饮食特化相关的形态差异。特别讨论了将个体发育异速生长用作减法标准的情况。双变量和多变量结果表明，物种间颅骨形态的大部分变异与将共同生长趋势扩展到不同大小有关。生长轨迹的比较分析揭示了一些差异，但没有一个差异似乎与颅骨比例的重新组织有关，而这种重新组织可能对应于向增加食叶性的饮食转变。然而，齿列明显表现出与饮食差异相对应的非异速生长形状变化。讨论了这些颅骨和牙齿模式差异的意义。
