What happened to hunting and foraging after the introduction of agriculture? Satellite imagery in the Andean highlands revealed 76 hunting traps, indicating hunting remained an important aspect of life. 🏺 A #FestivalOfArchaeology thread on #NatureAndArchaeology 1/11 🧵

Lethal plague outbreaks in Lake Baikal hunter-gatherers 5,500 years ago - Nature
Analyses of ancient DNA from hunter-gatherers near Lake Baikal in southeast Siberia around 5,500 years ago indicate that highly virulent Yersinia pestis emerged earlier than previously estimated, far from the next known cases of infection in Late Neolithic Europe.

A @nature.com study @ramiro-arqueo.bsky.social coauthored with Huarpe community leaders shows inhabitants of Argentina's Uspallata Valley welcomed migrants even during a crisis, and that people in the region are related to those buried there 2000 years ago. www.nationalgeographic.com/history/arti...

Ancient graves reveal unexpected link to modern Andean people
The findings also reveal that while people in other regions resorted to violence, inhabitants of the Uspallata Valley lived peacefully with migrants during a time of crisis.

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.

Ramiro Barberena @ramiro-arqueo.bsky.social · 20/03/2026
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…

Ramiro Barberena @ramiro-arqueo.bsky.social · 20/03/2026
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.
111
Ramiro Barberena @ramiro-arqueo.bsky.social · 20/03/2026
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.
