The development of agriculture significantly changed the lives of early South American peoples primarily through the response: Groups started to settle in one place.
With the ability to cultivate crops and raise livestock, these communities could establish permanent settlements instead of relying on a nomadic lifestyle based on hunting and gathering. This shift led to population growth, the development of more complex societies, and ultimately contributed to the rise of civilizations in the region. While the other responses may also have some relevance, the core change was the move from a nomadic to a settled lifestyle due to agriculture.
