Mobility and settlement strategies in southern Iberia during the Last Glacial Maximum: Evaluating the region's refugium status

The emergence and distribution of the Solutrean technocomplex in Western Europe is credited as a direct result of climatic changes associated with the Last Glacial Maximum. Across Iberia, spatial clusters of sites are considered to reflect the deliberate occupation of regional refugia which enabled human survival. In southern Iberia in particular, it is commonly thought that benign climatic conditions made it a regional refugium that was especially attractive for human settlement. However, this perspective has endured without a critical examination of its refugium status, thereby hindering a more comprehensive understanding of hunter-gatherer mobility and settlement in the region. Drawing on the relationship between lithic technology, land-use strategies and ecology, this paper tests the assumption that mobility and settlement strategies in southern Iberia conform to expectations of hunter-gatherer behaviour in an ecological refugium. This is achieved using statistical analyses of retouched stone tool assemblages which serve as a proxy for site function and related strategies of mobility. The results demonstrate a considerable use of logistical mobility strategies which likely sought to overcome problems arising from unevenly distributed resources. These findings undermine the refugium status of southern Iberia and question the validity of a "refugium" concept for understanding the regional Solutrean record and beyond.
