Fluctuating and directional asymmetry in the long bones of captive cotton‐top tamarins (<scp><i>S</i></scp><i>aguinus oedipus</i>)

This first study of DA and FA among multiple dimensions throughout the limbs of a non-hominoid primate suggests that previously-reported patterns of human bilateral asymmetry are not exclusive to humans. The results further indicate potential underlying differences in constraints on variation within limb bones. While processes shaping variation await further study, our results argue that different long bone dimensions may reflect dissimilar evolutionary processes.
