Why Black Irish DNA Is The Strangest Survival Story In European Genetics

Описание: #ancientdna #irish #ireland
Why do the most genetically ancient people in Ireland carrying a DNA signature that predates Celts and Vikings look remarkably different from the standard Irish stereotype with dark hair and olive skin? This investigation explores the Black Irish phenotype and the mapping of over one thousand Irish genomes that disproved the popular myth of shipwrecked Spanish Armada sailors. From the discovery of ten distinct genetic clusters on a single small island to the silent medical legacy of hereditary hemochromatosis we uncover a story of geographic isolation and accidental preservation. We reveal how the ethnic cleansing by Oliver Cromwell inadvertently pushed this Bronze Age population to the harsh western Atlantic coast preserving the oldest face in Ireland while simultaneously shipping others off to the Caribbean.
