Yamnaya steppe ancestry

Maps of expansion of “Steppe ancestry” with (Pre-)Yamnaya/Bell Beaker and Corded Ware, from the collection of Maps of prehistoric migrations.

For context and reference, please read the book on Indo-European and Uralic migrations.

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.

Image based on published maps on steppe ancestry expansion and data published, e.g. steppe components in Olalde et al. (2018) Supplementary materials.
