  1. (A) Single-source models to assess continuity of each Sardinian period with the previous one (see main text for guide to abbreviations). (B) Results of two-way models of admixture for Cagliari (a representative present-day sample). (C) Results of three-way models showing multiple eastern Mediterranean populations that can produce viable models (Results shown with individuals from Lombardy [Bergamo in the Human Origins array (HOA) dataset, see Methods] as one of several possible proxies for north Mediterranean ancestry, see part C). (C) Results of three-way models showing multiple north Mediterranean populations that can produce viable models (Results shown with Jewish individuals from Turkey [‘Turkish-Jew’ in the dataset] used as one of several possible proxies for east Mediterranean ancestry, see part B). (E) Results of single-source models to assess continuity among post-Nuragic sites. (F) Results of single-source models to assess continuity between the Medieval period samples and present-day samples (Cagliari and Ogliastra taken as representatives). Full results are reported in Supp. Info. 4.
