(A) PCA of 429 present-day west Europeans (gray dots) with previously published Western HG (WHGs), Atlantic coast and Central European Neolithic farmer samples (filled symbols), and the samples from the present study (shaded symbols) projected onto the first two principal components (more details in SI Appendix, Section S11.1). (B) Inferred ancestry components (assuming seven clusters) of ancient individuals (Methods and SI Appendix, Section S11.2). All individuals to the left of Yoruba are prehistoric individuals, all of which are shotgun-sequenced unless marked with “CP” for SNP capture data. In the label names, the following letters indicate an archaeological context: CA, Chalcolithic; EN, Early Neolithic; N, Neolithic; MN, Middle Neolithic; LN, Late Neolithic. The LN individuals from Portugal come from different sites (key provided in Dataset S1.3).
