steppe-ancestry-corded-ware — Tentative map of fine-scale population structure during steppe-related expansions (ca. 3500–2000 BC), including Repin–Yamna–Bell Beaker/Balkans and (Sredni Stog?)Late Trypillia–Corded Ware groups. Data based on published samples and pairwise comparisons tested to date. Notice that the potential admixture of expanding Repin/Early Yamna settlers in the North Pontic area with the Late Trypillian (and thus Late Trypillian-related ancestry in Yamna) has been omitted for simplicity purposes, assuming thus a homogeneous Yamna vs. Corded Ware ancestry.
