If Your Family Has O Negative Blood — DNA Finally Revealed Where It Really Came From

If You Have O Negative Blood, Your DNA Tells an Ancient Story — Here's What Science Actually Found O negative blood makes up just 6-7% of the population, but its origins trace back further than almost anyone realizes. In this video, we dig into the real, peer-reviewed genetic research connecting O negative and Rh-negative blood to some of the oldest surviving populations in Europe — from the mysterious Basque people of the Pyrenees (who carry Rh-negative rates up to 35%) to Mesolithic hunter-gatherers in Britain, to the 2022 Nature study that sequenced DNA from Black Death victims buried in a 1348 London plague pit. We cover: 🧬 Why O negative is the universal donor — and why hospitals are always short of it 🧬 The Basque genetic anomaly and their mysterious language isolate 🧬 Cheddar Man and Britain's earliest post-Ice Age inhabitants 🧬 The 2022 East Smithfield plague cemetery DNA study and the ERAP2 gene 🧬 What's actually proven vs. what's exaggerated online about blood type and disease resistance 🧬 Why Rh-negative blood is still one of population genetics' unsolved puzzles If this blew your mind, consider donating blood — especially if you're O negative.
