Researchers at the Centro Nacional de Investigación sobre la Evolución Humana (CENIEH) have led a study, recently published in the Journal of Human Evolution, on the diet of individuals at the Sima de los Huesos site (Sierra de Atapuerca, Burgos) by reconstructing their eating habits based on dental wear. In addition, the study examined whether the dental wear reflects the environmental conditions of the glacial period known as MIS 12, one of the coldest globally, which would have favored a significant expansion of semi-arid vegetation on the Iberian Peninsula around 450,000 years ago.
