Quick Summary
A new study reveals that farming in Argentina’s Uspallata Valley was adopted by local hunter-gatherers rather than introduced by outside populations. Centuries later, a stressed group of maize-heavy farmers migrated into the region, facing climate instability, disease, and declining numbers. Despite these pressures, there’s no sign of violence—instead, families stayed connected across generations, using kinship networks to survive. The research shows how cooperation, not conflict, helped communities navigate crisis.
