Known as earthworks, they were shaped by indigenous peoples who lived in the area around 500 to 1,500 years ago. Many Amazonian earthworks that predate the arrival of European colonizers are revealed in deforested areas. Heckenberger, who was not involved in the study, has conducted research in the Brazilian Amazon since the 1990s, working with indigenous peoples of the Xingu region. These findings further demonstrate that the cultural heritage of indigenous peoples in the Americas and elsewhere is “remarkably dynamic and innovative,” he added. So the scientists also mapped 937 known earthworks, instructing the model to highlight locations for potential earthworks that shared similar topographic features with previously detected sites.
