@microarch-lab.bsky.social was lucky enough to host and work with @bbonucci.bsky.social this summer. Checkout her recent publication on retrieving #ancientDNA from concretions from human remains!

Biancamaria Bonucci @bbonucci.bsky.social · Aug 19

🚨Thrilled to share our new paper!!
We were able to retrieve ancient DNA and proteins from layers of sediment attached to the skeletal remains of individuals from a Neolithic site from Southern Italy 💀🧬🦠

Ancient DNA reveals farming spread through migration, locals slow to adopt it | Penn State University

Roughly 10,000 years ago, humans started shifting from being nomadic hunter-gatherers to building large agricultural settlements, marking one of the greatest transformations in human history. For deca...

Checkout a recent publication from the Huber lab using #ancientDNA to measure how migration & cultural adoption each contributed to the expansion of farming. Migration of farming groups was the dominant factor & cultural adoption by hunter-gatherers was minimal.

The Neolithic Revolution marked an important shift from foraging to farming in human society. Here, the authors show that in Europe the spread of farming involved mostly within-group mating and limite...
