Table 1. Admixture modelling of Bronze Age populations.

For each test population, mixture proportions from four source populations with their standard errors are given. Ancestry is inferred from both ‘ultimate’ sources representing the earliest populations, and ‘proximate’ sources representing populations down to the Bronze Age (Supplementary Information, section 2). Column A lists ‘northern’ sources from eastern Europe and Siberia, including the Eurasian steppe; column B lists ‘eastern’ sources from Iran, the Caucasus, and Anatolia (after the Early Neolithic); column C lists ‘local’ sources from Anatolia and the Aegean; column D lists sources from the Levant. For abbreviations of population names see Methods.
