The Centro Nacional de Investigación sobre la Evolución Humana (CENIEH) has taken part in a study published in the International Journal of Osteoarchaeology that provides new insights into subsistence strategies during the Middle to Upper Paleolithic at the site of Cova Eirós (Cancelo, Triacastela, Lugo). The research applies a collagen-based approach to improve the taxonomic identification of faunal remains.
