An organism's size is perhaps its most apparent characteristic. The recent outpouring of
studies on the influence of body size on all aspects of biology and evolution and the …

Whether broadly (58, 60) or narrowly (10, 11, 14, 33, 34, 63) construed, morphometrics
clearly has something to do with the assignment of quantities to biologic shapes. In most …

Many problems in comparative biology and biological anthropology require meaningful
definitions of “relative size” and “shape.” Here we review the distinguishing features of ratios …

The subject of allometry is variation in morphometric variables or other features of organisms
associated with variation in size. Such variation can be produced by several biological …

The relationship between ontogenetic, static, and evolutionary levels of allometry is
investigated. Extrapolation from relative size relationships in adults to relative growth in …

The domestic dog varies remarkably in cranial morphology. In fact, the differences in size
and proportion between some dog breeds are as great as those between many genera of …

Extant terrestrial mammals span an enormous size range, from tiny pygmy shrews weighing
in at less than 5 g to massive African elephants tipping the scales at over 2500 kg …

A method is presented that constrains principal components analysis (PCA) to extract a first
component that, by definition, summarizes isometric size alone. The remaining information is …

The African apes represent a group of closely related primate taxa that differ substantially in
adult body size. The close phylogenetic affinity of pygmy chimpanzees (Pan paniscus) …

Bivariate and multivariate analyses of 55 cranial dimensions were completed on ontogenetic
series of Pygmy chimpanzees (Pan paniscus), Common chimpanzees (Pan troglodytes) …
