Tendencias en el Consumo de Alimentos en las Sociedades Prehispánicas de Quebrada de Humahuaca (Jujuy, Argentina)

A stable isotope analysis of human bone remains from Quebrada de Humahuaca, Argentina, reveals that maize (and/or amaranth) was the predominant dietary resource across three pre-Hispanic periods: Late Formative (500-900 AD), Regional Development Period (900-1430 AD), and Inca Period (1430-1536 AD). The study, which analyzed 41 individuals using carbon (δ¹³C) and nitrogen (δ¹⁵N) isotopic compositions, found no significant dietary shifts over time. Researchers employed a Bayesian mixing model to integrate isotopic data from modern plants and camelid fauna, providing insights into the agropastoral economies of these societies. This approach enhances our understanding of social and productive organization in the region.
