    Enthésopathies et activités des hommes préhistoriques (recherche méthodologique et application aux fossiles européens du Paléolithique supérieur et du Mésolithique)

    Les enthésopathies sur le squelette sont considérées comme des "marqueurs d'activité" en anthropologie biologique. L'étude de tels "marqueurs" pour des fossiles européens du Paléolithique supérieur et du Mésolithique offre l'opportunité d'enrichir notre connaissance des comportements et des modes de vie de ces populations et d'en illustrer certains aspects inconnus, notamment la division sexuelle du travail. Les lacunes méthodologiques (absence de référence médicale et de validation) que présente cette approche m'ont conduit à proposer une nouvelle méthode d'étude. Cette méthode, composée de 4 systèmes de cotation, a été testée sur un échantillon de référence (âge au décès, sexe et activité connus). L'analyse a permis de caractériser une relation entre les modifications osseuses et l'activité physique pour l'un des systèmes. Ce dernier a ensuite été appliqué à un ensemble de fossiles européens du Paléolithique supérieur et du Mésolithique (n = 95) dont les caractéristiques biologiques (âge et sexe) ont été réévaluées au moyen de méthodes fiables. Les résultats attestent de l'intérêt de la démarche. D'une part, ils permettent d'avancer l'hypothèse d'une division sexuelle du travail à ces périodes, avec une pratique du lancer dévolue aux hommes. Ils révèlent d'autre part des différences comportementales entre les populations gravettiennes et celles des périodes plus récentes, impliquant notamment une réduction des distances parcourues et une intensification de l'exploitation du milieu à la fin du Paléolithique supérieur et au Mésolithique.In bioarchaeology, enthesopathies i.e. "musculoskeletal stress markers" are assumed to reflect the activity of the attaching musculature. The study of enthesopathies in European Upper Palaeolithic and Mesolithic human fossils offers the opportunity to improve our knowledge of the behaviours and lifestyles of these populations and to reveal some unknown aspects like sexual division of labour. The methodological gaps in this approach (e.g. absence of medical reference and validation) led me to propose a new method of studying enthesopathies based on current medical data. This method consists of four scoring systems and has been tested on a reference sample of known age at death, sex and activity. The analysis has established a link between osseous modifications and physical activity for one of the systems. The latter has been applied to a sample of Upper Palaeolithic and Mesolithic fossils (n = 95) after a new assessment of their sex and age at death by using reliable methods. The results give evidence of the relevance of this approach. First, they allow to propose the hypothesis of a sexual division of labour during this period, with throwing activities devolved to men. Second, the results reveal behavioural differences between Gravettian populations and more recent ones, implying a reduction in mobility and an intensification of subsistence activities at the end of the Upper Palaeolithic and during the Mesolithic.BORDEAUX1-Bib.electronique (335229901) / SudocSudocFranceF

    Subsistence activities and the sexual division of labor in the European Upper Paleolithic and Mesolithic : Evidence from upper limb enthesopathies

    Studies of cultural artifacts and faunal remains from European Upper Paleolithic and Mesolithic sites indicate a shift in hunter gatherer subsistence strategies, involving an intensification and diversification of resource exploitation relative to earlier foragers during the Tardiglacial and Postglacial periods. This trend has been recognized as well through the analysis of non-pathological skeletal adaptations of the upper limbs of European Upper Paleolithic human fossils. These paleoanthropological studies of adaptive bone modeling also raise the question of female use of throwing-based weapon technology in the Upper Paleolithic. Here, we studied another type of osteological marker of activity, enthesopathies, of the upper limb remains of 37 European Upper Paleolithic and Mesolithic human fossils, with the goal of testing two hypotheses: 1) that activity levels were heightened at the end of Upper Paleolithic and into the Mesolithic relative to earlier foragers of the Gravettian, and 2) that there was an absence of a marked sexual division of labor in European hunter-gatherers during this time span. Our results are consistent with the first hypothesis; upper limb enthesopathies are significantly less frequent in the Gravettian group, but raise doubts about the second hypothesis. Four males exhibit lesions that can be confidently associated with throwing activities, while no females exhibit such lesions
