Admixture analysis for modern Europeans, arranged by percentage of Steppe ancestry (Yamnaya or early Corded Ware).

Here, Iran_N also encompasses Caucasus Hunter-Gatherer ancestry; the populations were relatively similar but not identical. CHG was omitted as Steppe populations carried 25-35% CHG ancestry and including both sources disrupts the model.

Iran_N/CHG and Natufian ancestry are mostly derived from Roman Imperial era Greeks and Anatolians. Note that modern Sicilians and Greek islanders display high genetic similarity. These populations have changed little since the Imperial era.

Iberomaurusian is North African Hunter-Gatherer ancestry, which has been present in Iberia since the Neolithic. It increased with Punic, Roman, and Muslim colonization, but exists at low frequencies today, < 5% on average.

Krasnoyarsk_BA represents Proto-Uralic East Siberian ancestry, which correlates with East European Hunter-Gatherer ancestry (Sidelkino), as these populations mixed when Proto-Uralics migrated westward.
