Deviations from the perfect symmetry of normally bilateral symmetrical characters occur during individual development due to the influence of multiple factors. Fluctuating asymmetry (FA) is the random developmental variation of a trait (or character) that is perfectly symmetrical, on average, across a population. Directional asymmetry (DA) occurs when one side of the pair of body sides is strongly more marked. Objective: We investigated the presence and level of skull FA and DA in the Araucan horse, a breed from East Colombia. Study Design: A sample of 21 skulls belonging to adult animals was studied by means of standard geometric-morphometric methods using 16 landmarks on the dorsal aspect of the crania. Results: Measurements showed a significant DA with a consistent rightward shift of the splanchnocrania. Conclusions: The results of this study raise questions about the influence of masticatory biomechanics on the asymmetric development of the skull, and also about how management and ingesta-specific properties (such as abrasiveness) may influence this asymmetry. |
