8. Norte Chico
The Norte Chico civilization, flourishing between 3000 and 1800 BCE along Peru’s arid coastline, is among the oldest known complex societies in the Americas (history.com). They are renowned for their monumental architecture, including large platform mounds and sunken circular plazas, exemplified by the Sacred City of Caral. Notably, the Norte Chico lacked ceramics and developed a unique form of record-keeping using knotted fiber artifacts, similar to the quipu system later used by the Inca. These artifacts suggest an early form of information encoding, though their exact purpose remains a subject of ongoing research.
