If You Have RH Negative Blood — DNA Finally Revealed Where They Really Come From

In the summer of 1939, a pregnant woman in New Jersey nearly died from a transfusion of her own husband's "matching" blood. Over the following hours, she received blood from 104 different donors, reacting violently to some and not others, as if her body was hunting for something specific most people don't carry. That case cracked open the discovery of a second blood group system: Rh factor. And one small corner of Europe carries it at rates that still puzzle scientists today. In this video, we break down: ✅ The 1939 New Jersey case and the 1940 Landsteiner-Wiener discovery of the Rh factor ✅ The devastating history of hemolytic disease of the newborn, documented as far back as 1609 ✅ How RhoGAM turned a leading cause of infant death into something most parents never hear about ✅ Why the Basque Country carries Rh-negative blood at 25-35%, nearly double the global average ✅ How ancient DNA traces Basque ancestry to Ice Age hunter-gatherers who barely mixed with incoming farmers ✅ The puzzling spike of Rh-negative blood among the Blackfoot and Blood tribes of North America ✅ The "drowned coastlines" theory connecting Rh-negative hotspots to Doggerland and Sundaland ✅ Competing disease-resistance theories: Toxoplasma gondii and the Black Death ✅ The real genetics behind "blue blood" and European royal inbreeding ✅ Why alien-ancestry and Atlantis theories about Rh-negative blood are compelling but unsupported by the evidence ✅ What COVID-19 research found about Rh-negative blood type and severity of illness 🔔 Subscribe for more deep dives into genetics, ancient DNA, and the science hidden in your own blood. 👍 Like this video if this changed how you think about your blood type. 💬 Comment below: What's your blood type, and does any of this match your family history? #RhNegative #BasquePeople #Genetics #DNA #MedicalHistory #AncientDNA #BloodType #RhoGAM #PopulationGenetics #ScienceExplained
