Modeling the European Neolithic expansion suggests predominant within-group mating and limited cultural transmission
Overview
Paper Summary
This study used computer simulations, including reaction-diffusion and agent-based models, to investigate how farming spread across Neolithic Europe. The results suggest that the expansion was primarily driven by the migration of farmers, with very limited cultural transmission to hunter-gatherer groups. Specifically, they estimate that less than 0.1% of farmers converted a hunter-gatherer to farming each year.
Explain Like I'm Five
This research used computer simulations to figure out how farming spread through Europe long ago. It turns out that people mostly moved and taught their neighbors, rather than just sharing ideas.

Rating Explanation
This research presents a strong, interdisciplinary approach to understanding the Neolithic expansion. By combining archaeological and genetic data with sophisticated modeling techniques, the authors offer compelling evidence for a predominantly demic spread of agriculture. While some model limitations exist, the robustness of their findings across diverse models and datasets warrants a strong rating.
