Influence of Size and Proportions on the Biomechanics of Brachiation

In an earlier study (Preuschoft and Denies, 1984), we investigated the biomechanical advantages of the considerable arm length in brachiators—a wellknown phenomenon. We showed that longer arms increase traveling velocity in arm-swinging locomotion. In addition, it provides a quicker start and reduces 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.
