5,000 years ago, a migration shaped Europe’s future. Migrating communities spread across Europe within two centuries, leaving lasting changes in interconnectivity, language, and ancestry. Yet these migrating communities did not enter an empty continent. Across Europe, they encountered indigenous communities with millennia-old roots. What interactions between migrating and indigenous communities gave rise to those lasting changes? This study sheds new light on this question with an innovative approach to ceramics. Ceramics bear traces of the production techniques which potters learned and applied to create them. The approach developed here combines a chaîne opératoire analysis of these traces with network analysis and probability theory to provide a quantitative estimate of the amount of shared knowledge between the prehistoric potters who made these ceramics. This approach is applied to ceramics from migrating Corded Ware communities and indigenous Funnel Beaker West communities in
