Extended Data Fig. 3: SOURCEFIND ancestry profiles for archaeological sites and outlying individuals.
From: Continental influx and pervasive matrilocality in Iron Age Britain
Surrogate and target individuals are listed with their population IDs in Supplementary Table 12. Raw values are available in Supplementary Table 17. The top rows show averaged profiles for Bronze and Iron Age archaeological sites in Britain, France and the Netherlands. British site profiles are outlined in black if the site contains one or more individual outliers (those possessing a level of British Early Bronze Age ancestry two standard deviations below the population mean). The bottom row shows ancestry profiles for these outlying genomes. We note that all Middle and Late Iron Age outliers derive from the channel core region. We identify two previously reported17 EEF outliers from Margetts Pit and Cliffs End Farm in Middle-Late Bronze Age Kent, who possess little to no British Early Bronze Age ancestry. (BA: Bronze Age, EIA: Early Iron Age, MIA: Middle Iron Age, LIA: Late Iron Age).
