Study: Amazonian Regions were Agricultural Landscapes Some 10,000 Years Ago

Far from being a rainforest and vast wilderness, certain Amazonian areas were cultivated by people for crop-growing. Scientists have discovered that humans residing in remote regions of now present-day Bolivia were planting crops such as cassava, squash, and maize. Inhabitants also developed thousands of "forest islands" which are small mounds of lands, and where there is proof of plant cultivation.
