Seasonality and mobility: An Integrative framework for reconstructing Kura-Araxes pastoral systems at Maxta I, Nakhchivan The Kura-Araxes Culture (3500–2500 BCE) is often depicted as a homogeneous pastoralist horizon, yet its internal economic and mobility strategies remain poorly understood. This study for the first tim...

We are pleased to share our new paper on the Iberian Aurignacian. We employed a quantitative approach to explore techno-typological variability and test its spatio-temporal dimension.

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.

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.

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…

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.

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.

Just out in
@Nature
! 🌽
The history of farming in the southern Andes.

In a collaboration between archaeologists, geneticists and Huarpe Indigenous communities, we investigate its origins and consequences in the Uspallata Valley.

Avanza el conocimiento y ahora comprendemos mucho más sobre la incorporación de la agricultura del maíz en el sur andino 🌽 Excelente trabajo de @ramiro-arqueo.bsky.social y colegas aportando desde múltiples especialidades.

Congratulations to my former lab at @pasteuredu.bsky.social @nrascovan.bsky.social lead authors @ramiro-arqueo.bsky.social and #pierreLuisi and last but not least thanks @bitesizedna.bsky.social for hosting me at Copenhagen Uni for hours of drilling, extractions, and preps! 👩‍🔬

@institutpasteur.bsky.social @nrascovan.bsky.social

Archaeologists, geneticists and Indigenous communities together. How did agriculture spread in the Andes? Migration? Cultural exchange? How did farming affect human lives?
Tomorrow we share new archaeological and ancient DNA evidence from the Southern Andes

Stay tuned! #archaeology #dna @nature.com

🧬 Two pathogens, one disease.
Leprosy cannot be understood as a single-pathogen disease.
Understanding this duality is critical for modern case detection, surveillance, and long-term control strategies.
