Los irlandeses negros nunca fueron quienes pensábamos: el ADN finalmente reveló la verdad

The 2017 Irish DNA Atlas Project, led by researchers at Trinity College Dublin and the Royal College of Surgeons, analyzed individuals whose grandparents all came from the same region of Ireland. What they found dismantled the idea of ​​a single, homogeneous Irish population. Ireland was divided into 10 distinct genetic groups. The oldest and most genetically distinct were concentrated in the west—the same counties most consistently associated with Black Irish features. The Spanish Armada theory falls apart because the math doesn't work. A few dozen shipwreck survivors can't move the needle on a national gene pool. The Viking signal is real and measurable, but it's concentrated in the east, in the cities the Vikings built. The real answer requires a completely different timescale. What produced the Black Irish face isn't a foreign import. It's what happens when ancient genetics refuse to die.
