Scientists Compared Jewish DNA to Every Race on Earth — The Results Shocked Everyone

What does DNA actually reveal about Jewish ancestry? Population geneticists compared the genomes of Jewish communities worldwide with non-Jewish populations and found a story of near extinction, hidden relatives, and a Levantine thread that never snapped. The story starts in Erfurt, Germany, in 1349, with a medieval Jewish cemetery that was destroyed, forgotten, and rediscovered in 2013. The DNA in those teeth helped answer a question scientists had been circling for decades. 🧬 What you'll learn: The 2010 Nature and AJHG studies showing shared Middle Eastern ancestry in Ashkenazi, Sephardic and Mizrahi Jews The Cohen Modal Haplotype and what Y-chromosome research found about the priestly lineage The medieval Ashkenazi bottleneck, a founding group estimated at around 350 people, and why every Ashkenazi Jew is at least a 30th cousin The founder effect, Tay-Sachs, Gaucher disease and BRCA mutations, and the tuberculosis-protection hypothesis The 2022 Cell study of ancient DNA from medieval Erfurt, which found two distinct genetic groups The Khazar theory and why the genetic evidence doesn't support it Spain's hidden Sephardic ancestry, 500 years after the Inquisition Mizrahi Jews, the Beta Israel of Ethiopia, and the Bene Israel and Cochin Jews of India Why scientists found no evidence of any racial hierarchy 💬 Where does your family come from, and what have you always believed about your ancestry?
