The earliest known settlements in southwestern Amazonia date to thousands of years before the rise of agriculture in the area. Researchers have found that between 10,600 and 4,000 years ago, hunter-gatherers settled for at least part of the year at sites in an expanse of tropical savanna known as the Llanos de Moxos in northern Bolivia.
