How did the development of agriculture change the lives of early south american peoples? a. more groups moved near the coasts. b. groups started to settle in one place. c. civilizations quickly developed. d. many groups developed a social hierarchy.

The correct answer is: Option B. Groups started to settle in one place.

The practice of agriculture was the catalyzer for every civilization that migrated by the Bering Strait to develop permanent settlements in the Americas, the earliest of which are estimated to date back to 6500 B.C. near the Amazon Basin.

The most prominent groups to be identified in the South Americas as the early settles would be the Huaca Prieta in Peru (4700 B.C.), and the Valdivia in Ecuador (3500 B.C.).
