<p style="text-align: justify;">Reduced mobility associated with captivity induce changes in biomechanical stress on the skeleton of domesticated animals. Due to bone plasticity, the morphology and the internal structure of the bones can respond to these new biomechanical stresses over individuals’ lifetime. In a context where documenting early process of animal domestication is a real zooarchaeological challenge, this study will test the hypothesis that change in mobility patterns during the life of a wild ungulate will alter internal structure of its limb bones and provide a proof of concept for its application in Zooarchaeology. Using the calcaneus as phenotypic marker through qualitative and quantitative 3D microanatomical analyses, we relied on a comparative study across wild boars (Sus scrofa) populations from controlled experimental conditions with different mobility patterns (natural habitat, large pen and stall) and archaeological specimens collected from middle and late Mesolithic as surrogate for the norm of reaction in European wild boar phenotype before the spread of agriculture and domestic pigs. Results provide evidence for compressive and tensile forces as main elements affecting the variation in the cortical thickness along the calcaneus. Furthermore, changes in the internal structure of the calcaneus between mobility patterns are observed but their intensity is not directly associated with the degree of mobility restriction and only weakly impacted by the size or weight of the individuals. Despite having greater bone volume, the calcaneus of the Mesolithic wild boars displays a very similar microanatomy compared to the present-day hunted or captive wild boars, these results suggest that calcaneus microanatomy is more affected by population differences than by differences in locomotor contexts. For all these reasons, this preliminary study doesn’t support the use of microanatomy of the calcaneus as an indicator of change in locomotor behaviour induced by captivity in the archaeological record.</p> should fill this box only if you chose 'All or part of the results presented in this preprint are based on data'.
