>Do you believe todays Ashkenazi and Sephardic Jews are genetically related to the Hebrews of the Bible?
We applied a wide range of population genetic analyses to compare these two hypotheses. Our findings support the Khazarian hypothesis
One of the major challenges for any hypothesis is to explain the massive presence of Jews in Eastern Europe, estimated at eight million people at the beginning of the 20th century. We investigate the genetic structure of European Jews, by applying a wide range of analyses—including three population test, principal component, biogeographical origin, admixture, identity by descent (IBD), allele sharing distance, and uniparental analyses—and test their veracity in light of the two dominant hypotheses depicting either a sole Middle Eastern ancestry or a mixed Middle Eastern–Caucasus–European ancestry to explain the ancestry of Eastern European Jews.
After their conversion to Judaism, the population structure of the Judeo–Khazars was further reshaped by multiple migrations of Jews from the Byzantine Empire and Caliphate to the Khazarian Empire (fig. 1). Following the collapse of their empire and the Black Death (1347–1348) the Judeo–Khazars fled westward (Baron 1993), settling in the rising Polish Kingdom and Hungary (Polak 1951) and eventually spreading to Central and Western Europe. The Khazarian hypothesis posits that European Jews are comprised of Caucasus, European, and Middle Eastern ancestries.
