Résumé

The domestication involves changes in lifestyle of individuals that will cause changes in phenotype. For example, it has been established, that from the Neolithic some dogs, the first animal species domesticated, have been able to digest starch in large quantities. This new adaptation represents a crucial step in the evolution of the dog because it represents an adaptation to lifestyle of agricultural societies. As the structure of the masticatory apparatus is related to the type of diet, it is possible that the dietary change had an impact on the anatomy of the mandible. So, one of the goals of this study is to compare the morphological and morpho-functional evolution of the dogs mandibular apparatus link to the humans techno-economic evolution during Epipaleotithic until Bronze Age. To study the morphological diversity of mandible, traditional and geometric morphometric analyses were used on 627 mandibles of dogs and 94 mandibles of wolves from 36 archeological sites in Europe and Near and Middle East. These analysis showed the proximity between Paleolithic wolves and Mesolithic, Neolithic and Chalcolithic dogs in Europe. In addition, this study showed the development of new forms of dogs during the Neolithic and Chalcolithic in Europe. Moreover, after comparison with paleogenetic data, we assumed that the morphological and morpho-functional diversity of mandible of dogs were linked to the development of agriculture in Neolithic societies. This study highlights that there is a link between starch diet adaptations in ancient European dogs and a morphological specialization of the mandible.
