Influence of Size and Proportions on the Biomechanics of Brachiation,s the muscle force necessary to lift the body, i.e., reduces the energetic cost of locomotion. This seems to provide a fine explanation for why gibbons have long arms. Here we ask why these animals are not larger, and why their arms are not even more elongated.

Then it will be possible to compare the many different sizes, shapes, and modes of locomotion of the primates to those of the terrestrial vertebrates in general.

Gastrointestinal Allometry in Primates and Other Mammals, application of allometric principles to an entirely new area of research is provided by the work conducted by Chivers and Hladik (1980) on the morphology of the gastrointestinal tract in primates and other mammals. Further development of this particular approach forms the subject of this chapter.
