Odd shapes hidden in dense Amazon rainforest reveal sprawling ancient civilization

Recent discoveries in the Amazon rainforest have revealed extensive earthworks that suggest the existence of a sprawling ancient civilization. These earthworks indicate that approximately 3 million people may have inhabited just about 3% of the forest's total area. The findings highlight the complexity and scale of human activity in the region long before European contact. The newly identified structures include geometric shapes and mounds, which were previously obscured by dense vegetation. Researchers utilized advanced imaging techniques to uncover these hidden formations, leading to a better understanding of the societal organization and environmental management of the ancient inhabitants. The earthworks are believed to have been constructed over a significant period, showcasing the engineering capabilities of the civilization. This discovery challenges previous assumptions about the Amazon rainforest being a sparsely populated wilderness prior to modern times. Instead, it suggests that the region supported a large and sophisticated population that engaged in agriculture and other forms of land use. The findings underscore the importance of the Amazon not only as a natural ecosystem but also as a historical landscape shaped by human activity. Overall, the evidence of these ancient earthworks contributes to a growing body of research that redefines our understanding of pre-Columbian societies in the Amazon, emphasizing their impact on the environment and their role in shaping the region's history.
