Suppl. Graph. 1. PCA of ancient and modern Eurasian samples, labelled and unlabelled.

Suppl. Graph. 2. PCA of ancient and modern European samples, labelled and unlabelled. PC1 and PC2 have been inverted to fit the position of samples in the PCA of Eurasian individuals, which corresponds more naturally to the east–west and north–south distribution of populations.

Suppl. Graph. 3. PCA of ancient and modern Eurasian samples. Mesolithic and Neolithic cultures referenced.

Suppl. Graph. 4. PCA of ancient and modern Eurasian samples. Early Eneolithic admixture events in the steppe drawn.

Suppl. Graph. 5. PCA of ancient and modern Eurasian samples. Suvorovo-related admixture events in the Balkans drawn.

Suppl. Graph. 6. PCA of ancient and modern Eurasian samples. North Pontic admixture events drawn.

Suppl. Graph. 7. PCA of ancient and modern Eurasian samples. Late Repin admixture events drawn.

Suppl. Graph. 8. PCA of ancient and modern Eurasian samples. Corded Ware admixture events drawn.

Suppl. Graph. 9. PCA of ancient and modern Eurasian samples. Yamna Hungary – Early East Bell Beaker admixture event drawn.

Suppl. Graph. 10. Section of PCA of ancient and modern European samples. Yamna-related admixture events shown, including Bell Beakers, Balkan BA, Mycenaeans, and Armenia BA samples. Also marked are Assyrian and Old Hittite samples.

Suppl. Graph. 11. Section of PCA of ancient and modern European samples. Czech BA, Únětice, Poland BA, Late Trzciniec, and Baltic BA samples

Suppl. Graph. 14. PCA of ancient and modern Eurasian samples. Bronze Age and Iron Age Fennoscandian populations and Saami admixture drawn.

Suppl. Graph. 15. PCA of ancient and modern Eurasian samples. Ancient Palaeo-Laplandic, Palaeosiberian, and Altai clines drawn, with modern populations labelled.

Suppl. Graph. 16. PCA of modern Uralic-speaking peoples with Palaeo-Laplandic and Palaeosiberian clines drawn. Image modified from Tambets, Yunusbayev, et al. (2018).
