Neolithic Europeans Preferred to Migrate than to Teach Farming: A Simulation Study

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.

Identified Weaknesses

Simplified model assumptions

The models necessarily simplify complex population dynamics, such as the potential for individuals to revert from farming back to hunter-gatherer lifestyles. Although tested and shown to not significantly alter results, it is still an important limitation to consider.

Uncertainty in parameter values

Model parameters, such as carrying capacity and dispersal distances, are based on estimates and assumptions from prior research, which can introduce uncertainty into the model’s accuracy.

Precision of archaeological and genetic data

Inferring cultural transmission rates from ancient DNA requires precise dating of samples and archaeological sites, which may have a margin of error.

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.
