Briefing: Ancient DNA reveals a farming shift that pushed a society to the brink

A new study published in ScienceDaily reveals that local hunter-gatherers in Argentina's Uspallata Valley adopted farming practices, marking a pivotal transition in their subsistence strategies.

The introduction of maize-heavy agricultural systems led to increased societal stress, which may have affected the region's resource management and community structures.

Subsequently, a migration of farmers into the Uspallata Valley occurred centuries later, indicating a complex interplay of agricultural practices and population movements that could reshape local infrastructure demands.
