Principal component analysis (A) and Ward type hierarchical clustering (B) with 19 Western and Central European populations.

<p>On both image parts south-western European hunter-gatherers [HGSW] and Central European hunter-gatherers [HGC] are symbolised by grey hexagons, Early Neolithic Iberian groups (Central Portugal [CP_EN], north Spain [NS_EN], and northeast Spain [NE_EN]) by red circles and Middle/Late Neolithic groups by pink star and circles (Alto de Reinoso [Reinoso], north Spain [NS_MLN], northeast Spain [NES_MLN], south French Treilles group [TRE]). Magenta-coloured circles indicate the chalcolithic El Mirador cave [El_Mirador] and Late Neolithic-Chalcolithic Central Portugal [CP_LN_CH]. Early Neolithic groups in Central Europe and Carpathian Basin are represented by brown circles (Starcevo culture [STA], Linear pottery culture in Transdanubia [LBKT], Linear Pottery culture in Central Europe [LBK], Rössen culture [RSC], Schöningen group [SCG]), Middle Neolithic groups in Central Europe (Salzmünde Culture [SMC], Baalberge Culture [BAC], Bernburg Culture [BEC]) are in orange. (B) Cluster significance is given as AU (Approximately Unbiased) p-value in %, which is computed by multi-scale bootstrap resampling with 10,000 replicates (graphic: A. Szécsényi-Nagy).</p
