RESEARCH POPULATION GENETICS fromtheanalysisdatasetsindividualscoveredby <10,000 SNPs, with evidence of contamination, or first-degree relatives of others (table S1). We analyzed the data with principal components The genomic history of the Iberian analysis (PCA) (Fig. 1, C and D), f-statistics (11), and qpAdm (12) and summarize the results in Peninsula over the past 8000 years Fig. 1E. We confirmed the robustness of key findings by repeating analyses after remov- Iñigo Olalde1*, Swapan Mallick1,2,3, Nick Patterson2, Nadin Rohland1, ing SNPs in CpG dinucleotides (table S5) that Vanessa Villalba-Mouco4,5, Marina Silva6, Katharina Dulias6, Ceiridwen J.
