Cronologías de ancho de anillos de queñoa (Polylepis tarapacana) para los últimos 500 años en el Altiplano de la región de Arica y Parinacota, Chile

Arica and Parinacota's high-altitude environment holds clues to the Chinchorro culture's advanced practices, including artificial mummification, dating back over 500 years. This study reconstructs climate variability in the region using tree-ring width chronologies of queñoa (Polylepis tarapacana), capturing the last five centuries with unprecedented precision. The research reveals distinct periods of drought and moisture, correlating with historical records of human settlement patterns and cultural practices. By analyzing annual growth rings, scientists identified environmental stressors that likely influenced Chinchorro society's adaptations, providing a rare intersection of paleoclimatology and archaeological evidence in the UNESCO-listed Atacama Desert.
