BADEN-WÜRTTEMBERG, GERMANY—An analysis of DNA samples suggests that elite Iron Age Celts may have passed power along matrilineal lines, according to a Live Science report. The samples were taken from 31 skeletons recovered from seven burial sites in southwestern Germany that have been dated to the sixth and fifth centuries B.C. and include gold and bronze artifacts. State of Baden-Württemberg archaeologist Dirk Krausse and his colleagues identified two men buried in neighboring mounds who were likely an uncle and a nephew through shared maternal ancestry, while a woman and a man buried in mounds about 60 miles and 100 years apart may have been a great-grandmother and her great-grandson. Another two samples were found to have been individuals born to parents who were first cousins. Population geneticist Stephan Schiffels of the Max Planck Institute for Evolutionary Anthropology explained that although power was not commonly passed through the maternal line in Iron Age Europe, it was known to occur when confidence in an offspring’s paternity may have been low. “If a ruler has children on their own but also passes power to their sister’s children, then there might be an incentive to merge the direct and the sister’s lineage, which would then result in first-cousin matings through the female line,” he explained. “But we cannot prove such a scenario from the genetic data,” he cautioned.
