Over 20,000 Geoglyphs Uncovered in Amazon Rainforest Reveal Densely Populated Pre-Colonial Era
An extensive study has identified tens of thousands of geoglyphs, large earthworks, hidden within the Amazon rainforest. These findings suggest a significantly more populated pre-colonial Amazon than previously understood. Researchers estimate that between 1.25 and 3 million people inhabited just 3% of the Amazonian jungle approximately two thousand years ago. The discovery of these numerous geoglyphs points to sophisticated land management and societal organization in the region centuries before European arrival. This archaeological revelation challenges existing narratives about the Amazon's historical demographics and human impact.
The discovery of extensive geoglyphs in the Amazon challenges earlier assumptions about the region's pre-colonial population density and human impact. This finding highlights the potential for advanced societal structures and large-scale land modification by indigenous populations, suggesting a complex relationship between human activity and the Amazonian ecosystem long before modern times. Future research may explore the sustainability of these ancient populations and their environmental practices, offering insights into long-term ecological stewardship and the potential for large human settlements within the rainforest.
