Genetic nuance undercuts 'Aryan' nationalism

Ancient‑DNA and formal admixture models show that steppe‑related ancestry is a real but partial component of Iranian genomes; modern Iranian identity emerges from multiple earlier populations (Zagros, BMAC, steppe) rather than a single 'Aryan' source. That complexity means genetic evidence cannot straightforwardly validate nationalist narratives that claim exclusive steppe descent. — If amplified, this framing can weaken political claims that deploy simplistic genetic arguments for ethnic primacy and should influence how media, educators, and policymakers treat genetic evidence in identity debates.
