Modeling the Evolution of Ceramic Traditions Through a Phylogenetic Analysis of theChaines Operatoires: the European Bronze Age as a Case Study

Thechaines operatoiresunderlying the manufacture of objects are good proxies for studying social groups and how cultural traits are transmitted and modified through the learning process. With the rise of evolutionary archaeology, the evolution of ceramic vessels can be modeled by using cladistics to elaborate kinship relationships between different taxa on the basis of shared derived character states. Here the modeling applies to ceramic fashioning from the European Middle Bronze Age (France and the United Kingdom). The aim is to assess the nature of the evolution and the relationships between three main cultures-in southern England, Normandy, and in the center-west of France. The cladistics analysis highlights that the ceramic traditions largely result from a process of phylogenesis-a result of descent with modification from an ancestral assemblage-rooted in the Early Bronze Age, suggesting a common origin for the Trevisker/Deverel-Rimbury and French Atlantic technical traditions. On the other hand, the Norman appears to be related to the Duffaits tradition, but to the exclusion of the Trevisker/Deverel-Rimbury traditions. This study supports the theoretical premise that some technical sequences are more stable than others. The evolution of sequences requiring motor habits, such as shaping, stabilized fairly quickly, unlike the finishing operations that continued to diverge throughout the Bronze Age. This study suggests that cladistics based on the description of the ceramic material in terms of chaines operatoires is a useful tool for studying cultural change.
