Study: Ashkenazi Jews All Descended from Four Women

A new study finds that some 40% of the worlds 3.5 million Ashkenazi Jews are descended from four Jewish women who may or may not have lived in Central Europe where most of the Ashkenazi ended up. As you probably know, Jewish identity is matrilineal or passed on only by a mother, but this study focused on women because it involved mitochondrial DNA which is only passed on the female side. Also, chicks are more interesting to study.
