How did farming reach Uspallata?
Through migration of farmers—or through cultural transmission with local hunter-gatherers?
We address this through an integrative study of human remains spanning the last 2000 years, combining archaeology, isotopes and genomes.

We find strong genetic continuity through time, suggesting that agriculture spread without major population movement. Instead, local communities adopted farming practices while maintaining deep regional ancestry.

But we also find changes…
Isotopes reveal shifts in farming intensity, including a marked intensification of maize farming between ~800 and 600 years ago. And then we found something unexpected…

Strontium isotopes show that many of these individuals did not live in Uspallata and that the valley saw increased immigration. These were families with a matrilineal organization that migrated in succesive generations.

Artist: Mauricio Alvarez

Why did they leave their homes?
We suggest it was a response to a long and multicausal crisis. Low populaiton size, climatic instability and the transmission of infectious diseases-tuberculosis- triggered migration along social networks. This was a resilient response.

We are proud to integrate an amazing team: Guaytamari and Llahué Xumec Huarpe communities from Uspallata, @institutpasteur.bsky.social @erc.europa.eu National Geographic Society, CONICET, @wennergrenorg.bsky.social @nrascovan.bsky.social @fransantanas.bsky.social
