研究了个体发育水平、静态水平和进化水平异速生长之间的关系。从成人的相对大小关系外推到个体发育的相对生长取决于个体发育载体的斜率和截距相对于载体长度的变异性。如果斜率和截距的变异性相对于长度的变异性较低，个体发育和静态异速生长将是相似的。个体发育和静态异速生长的相似性进行了测试，通过比较第一主成分，或大小向量，48颅性状之间的相关性在横截面个体发育样本的恒河猴从卡约圣地亚哥与静态样本，所有年龄和性别相关的变化被删除。各分量之间的矢量相关性很高，但显著> 1;个体发育分量中明显的3种异速生长模式中有2种在静态分量中不可辨别。这表明，有重要的差异，在成人之间和个体发育的大小和形状的关系。从种内或种间表型异速生长到进化异速生长的外推依赖于遗传和表型异速生长模式的相似性。通过比较使用标准定量遗传方法计算的表型、遗传和环境相关矩阵的第一主成分来测试模式的相似性。表型异速生长、遗传异速生长和环境异速生长的模式是不同的，只有环境异速生长表现出个体发育异速生长模式。表型异速生长可能不是一个准确的指导模式的进化变化的大小和形状。
The relationship between ontogenetic, static and evolutionary levels of allometry is investigated. Extrapolation from relative size relationships in adults to relative growth in ontogeny depends on the variability of slopes and intercepts of ontogenetic vectors relative to variability in length of the vector. If variability in slopes and intercepts is low relative to variability in length, ontogenetic and static allometries will be similar. The similarity of ontogenetic and static allometries was tested by comparing the 1st principal component, or size vector, for correlations among 48 cranial traits in a cross-sectional ontogenetic sample of rhesus macaques from Cayo Santiago with a static sample from which all age- and sex-related variation were removed. The vector correlation between the components is high but significantly > 1; 2 of 3 allometric patterns apparent in the ontogenetic component are not discernable in the static component. This indicates that there are important differences in size and shape relationships among adults and within ontogenies. Extrapolation from intra- or interspecific phenotypic allometry to evolutionary allometry depends on the similarity of genetic and phenotypic allometry patterns. Similarity of patterns was tested by comparing the 1st principal components of the phenotypic, genetic and environmental correlation matrices calculated using standard quantitative genetic methods. The patterns of phenotypic, genetic and environmental allometry are dissimilar; only the environmental allometries show ontogenetic allometric patterns. Phenotypic allometry may not be an accurate guide to patterns of evolutionary change in size and shape.
