Nearly half of Ashkenazi Jews descended from just 4 women: South Florida Sun-Sentinel: "Some 3.5 million of today's Ashkenazi Jews _ about 40 percent of the total Ashkenazi population _ are descended from just four women, a genetic study indicates."
None of this is news to DovBear readers, who learned last year that we're all direct descendants of King David -- all of us, including non-Jews. We're all also probably descendants of Rashi and the Maharsha, too. Factor in rapes and intermarriage, and it's fair to argue that we're all also direct descendants of Mohammed, and Confucius. (Yes, that Mohammed.)
