I am interested in the subsistence economy of agropastoral communities from the beginning of domestication to the emergence of specialised 'breeds', using faunal remains found in archaeological contexts. This will enable me to address the issues surrounding breeding practices and techniques, pastoral practices and the morphological and phenotypic diversity of small livestock (sheep and goats) present in the north-western Mediterranean and south-western Asia during Protohistory. In order to disentangle the biotic and abiotic factors affecting the morphological diversity of domestic goats, I am also looking at the morphology of wild goats (e.g. ibex and thars), which are little affected by human impact in ancient populations. This allows me to examine the impact of the environment (ecomorphology) and climatic conditions on these animals present in southern France and attempt to reconstruct the rock ecosystems of this territory from the final Middle Pleistocene to the Holocene. To do this, I am using a range of complementary and innovative methods, from comparative anatomy to 3D geometric morphometry (GMM), as well as machine learning (ML) approaches in collaboration with mathematicians and statisticians.
