FLICKR, ADAM BAKERThe majority of Ashkenazi Jews are descended from prehistoric European women, according to study published today (October 8) in Nature Communications. While the Jewish religion began in the Near East, and the Ashkenazi Jews were believed to have origins in the early indigenous tribes of this region, new evidence from mitochondrial DNA, which is passed on exclusively from mother to child, suggests that female ancestors of most modern Ashkenazi Jews converted to Judaism in the north Mediterranean around 2,000 years ago and later in west and central Europe.

The new findings contradict previous assertions that Ashkenazi mitochondrial lineages originated in the Near East, or from mass conversions to Judaism in the Khazar kingdom, an empire in the north Caucasus region between Europe and Asia lasting from the 7th century to the 11th century whose leaders adopted Judaism. “We found that most of the maternal lineages don’t trace to the north Caucasus, which would be a proxy for the Khazarians, or to the Near East, but most of them emanate from Europe,” said coauthor Martin Richards, an archaeogeneticist at the University of Huddersfield in the U.K.

Richards and colleagues’ story “seems reasonable,” said Harry Ostrer, a human geneticist at Albert Einstein College of Medicine of Yeshiva University in New York City who was not ...

These fluttering sensations are the brain’s reaction to certain emotions, which can be amplified or soothed by the gut’s own “bugs".
