Figure 1. Geographic and genetic structure of 216 newly reported individuals.

Figure 1

A: Locations of newly reported individuals. B: Ancient individuals projected onto principal components defined by 777 present-day West Eurasians (shown in Extended Data Figure 1). Includes selected published individuals (faded circles, labeled) and newly reported individuals (other symbols, outliers enclosed in black circles). Colored polygons cover individuals that had cluster memberships fixed at 100% for supervised admixture analysis. C: Date (direct or contextual) for each sample and approximate chronology of southeastern Europe. D: Supervised ADMIXTURE analysis, modeling each ancient individual (one per row), as a mixture of population clusters constrained to contain Anatolian Neolithic (grey), Yamnaya from Samara (yellow), EHG (pink) and WHG (green) populations. Dates in parentheses indicate approximate range of individuals in each population. See Extended Data Figure 2 for individual sample IDs. Map data in A from the R package maps.
