In parallel, legumes were less cultivated since the Neolithic and probably used as a secondary plant resource by the Cantabrian communities.Discussion: Our results have also allowed us to corroborate previous regional archaeobotanical and isotopic data and enhance the archaeological evidence of plant consumption during Late Prehistory, establishing a diachronic multiapproach to the development of agricultural practices in this area and providing a methodological framework for future studies.
