Regions are built from modern-named provinces and districts that show stable, fine-scale genetic structure (for example, Galicia vs. Meseta vs. East-Mediterranean vs. South-Central Portuguese profiles). These modern anchors are then interpreted using Iberia-specific ancient DNA time-transects, archaeological and historical literature, and curated reference panels from published genetic studies.
