Análisis de isótopos estables en individuos subadultos del sitio arqueológico Los Amarillos (Quebrada de Humahuaca, Jujuy)

Researchers found evidence of early weaning among subadult individuals from the Los Amarillos archaeological site, part of the Quebrada de Humahuaca World Heritage Site. Using stable isotope analysis (δ13Cco, δ15N, and δ13Cap) on bone and dental remains from 22 subadults dating to the Regional Developments and Inca periods, the study revealed that weaning occurred earlier than previously thought, likely contributing to shorter birth intervals and supporting demographic growth during this period. The analysis relied on longitudinal studies of modern populations to refine age estimates, despite challenges posed by taphonomic processes and analytical limitations.
