The occupational sequence of Chiu Chiu's microbasin (Northern Chile) demonstrates that the area experienced significant changes in settlement patterns and artifact complexes, in a period of intense desertification, around 6000 years BP. One of the local responses to climate change was to settle more permanently near stable lake environments. This process reflect the economic changes that mark the initial social complexity of hunter-gatherer societies in the region.
