Urheimat Mismatch Index

Create a standardized 'Urheimat Mismatch Index' (UMI) that quantifies how far a present‑day population’s genetic profile projects from its current location after Procrustes alignment to a continental genetic–geographic surface. The index would decompose displacement into likely contributions (recent admixture, drift/isolation, sample bias) and require a published robustness map before any historical or political interpretation is attached. — A public UMI would let policymakers, journalists and courts distinguish robust population‑genetic signals from overstated origin or migration claims, reducing misuse of genetics in identity politics and legal cases.
