BORDEAUX, FRANCE—Jack Baker of the University of Bordeaux and his colleagues compared beads recovered from 112 Gravettian archaeological sites, sorted them into 134 different types based upon their raw materials and design, and determined that there were at least nine distinct cultures clustered geographically across Europe, according to a Science Magazine report. It had been previously thought that people living in Europe between about 34,000 and 24,000 years ago were all members of a monolithic Gravettian culture, based upon similarities in their figurines and spearpoints. Recent studies have found some differences between groups, however. For example, DNA analysis has identified two genetic lineages in Gravettian culture—one group centered around the Pyrenees Mountains along the border of France and Spain, and a second group based in central and eastern Europe. Baker found that the jewelry analysis is in line with genetic data, but with some additional subdivisions. The jewelry study also suggests there were separate culture groups in Moldova and southern Spain, which are areas where ancient DNA has not been recovered. Meanwhile, some groups in Italy who shared ancestors did not wear similar jewelry, and people in France and Belgium who wore similar ornaments were not related to each other. Patterns of bead differences that turned up in a jewelry tradition may be the result of cultural and genetic exchange with neighboring groups, Baker added.
