Why the Amish Carry Diseases Found Almost Nowhere Else — DNA Finally Explained

Why do the Amish carry diseases found almost nowhere else on Earth? It isn't inbreeding — first-cousin marriage has never been permitted. DNA finally explains it, and the real answer starts on a ship in the 1700s. This channel decodes the hidden genetics of isolated communities — the founder effects, bottlenecks, and migrations written into human bodies. Rigorous science, told like a story. No pseudoscience, ever.
