Ashkenazi Jews descend from 350 people, study finds
admin | November 2, 2023
A new study concludes that all Ashkenazi Jews can trace their ancestry to a bottleneck of just 350 individuals, dating back to between 600 and 800 years ago. The study, published in the Nature Communications journal Tuesday, was authored by Shai Carmi, a computer science professor at Columbia University, and more than 20 medical researchers from Yale, Columbia, Yeshiva Universitys Albert Einstein College of Medicine, Memorial Sloan-Kettering Cancer Center, Hebrew University of Jerusalem and other institutions. Researchers analyzed the genomes of 128 Ashkenazi Jews and compared them to those of non-Jewish Europeans in order to determine which genetic markers are unique to Ashkenazi Jews.
