La persistance technologique suite à la stabilité de la faune au cours du Pléistocène: un modèle pour reconstruire les stratégies d'adaptation du paléolithique basé sur une évolution en mosaïque

Prehistoric archaeology focuses on innovations, transformations, and turnovers. We focus instead on persistency, suggesting that technological persistency in prehistoric hunter-gatherers was triggered by the stability of prey. The technological persistency-faunal stability nexus was not only crucial to human prosperity but also provided safe ground for technological and behavioral innovations, facilitating further adaptation to changing conditions. This can be viewed in the framework of mosaic evolution. We present six cases of morphological stasis enabling trophic adaptations and five archaeological cases of technological persistency following faunal stability. This model could contribute to a better understanding of technological persistency and its evolutionary role.
