BBC News interviews Harry Ostrer, M.D., and The New York Times cites research by Gil Atzmon, Ph.D., in two articles about a new study on Jewish genetic history. The new study analyzed mitochondrial DNA, genetic information inherited through women, and found that at least 80 percent of Ashkenazi maternal ancestry hailed from Europe, not the Middle East, suggesting that many European Jewish communities were founded by men who married and converted local women. Dr. Ostrer is professor of pathology, of genetics and of pediatrics at Einstein and director of genetic and genomic testing at Montefiore Medical Center. Dr. Atzmon is associate professor of medicine and of genetics.
