==== Criticism of the Elhaik studies ====
Elhaik's 2012 study proved highly controversial. Several noted geneticists, among them Marcus Feldman, Harry Ostrer, Doron Behar, and Michael Hammer have maintained—and the view has gained widespread support among scientists—that the worldwide Jewish population is related and shares common roots in the Middle East, Feldman stated Elhaik's statistical analysis would not pass muster with most scientists; Hammer affirmed it was an outlier minority view without scientific support. Elhaik in reply described the group as "liars" and "frauds", noting Ostrer would not share genetic data that might be used "to defame the Jewish people". Elhaik's PhD supervisor Dan Graur, likewise dismissed them as a "clique", and said Elhaik is "combative" which is what science itself is.
Elhaik's 2012 study was criticized in a 2013 paper in Human Biology for its use of Armenians and Azerbaijani Jews as proxies for Khazars and for using Bedouin and Jordanian Hashemites as a proxy for the Ancient Israelites. The former decision was criticized because Armenians were assumed to have a monolithic Caucasian ancestry, when as an Anatolian people (rather than Turkic) they contain many genetically Middle Eastern elements. Azerbaijani Jews are also assumed for the purposes of the study to have Khazarian ancestry, when Mountain Jews are actually descended from Persian Jews. The decision to cast Bedouin/Hashemites as "proto-Jews" was especially seen as political in nature, considering that both have origins in Arab tribes from the Arabian Peninsula rather than from the Ancient Israelites, while the descent of the Jews from the Israelites is largely accepted.
Geneticists conducting studies in Jewish genetics have challenged Elhaik's methods in his first paper. Michael Hammer called Elhaik's premise "unrealistic," calling Elhaik and other Khazarian hypothesis proponents "outlier folks … who have a minority view that's not supported scientifically. I think the arguments they make are pretty weak and stretching what we know." Marcus Feldman, director of Stanford University's Morrison Institute for Population and Resource Studies, echoes Hammer. "If you take all of the careful genetic population analysis that has been done over the last 15 years … there's no doubt about the common Middle Eastern origin," he said. He added that Elhaik's first paper "is sort of a one-off." Elhaik's statistical analysis would not pass muster with most contemporary scholars, Feldman said: "He appears to be applying the statistics in a way that gives him different results from what everybody else has obtained from essentially similar data."
Das, Elhaik and Wexler's 2016 study was challenged by the historian of Soviet and East European Jewry Shaul Stampfer, who dismissed it as 'basically nonsense', and the demographer Sergio DellaPergola, who claimed it was a "falsification", whose methodology was defective in using a small population size and failing to factor in the genetic profiles of other Jews such as the Sephardic Jews to whom the Ashkenazi Jews are closely related. Elhaik replied that factoring in the DNA of non-Ashkenazic Jews would not alter the genetic profile of Ashkenazi Jews, and that his team remained the largest genomic study of the latter to date, and the first to target Yiddish speakers. The Yiddish scholar Marion Aptroot states "Seen from the standpoint of the humanities, certain aspects of the article by Das et al. fall short of established standards."
Recently, a study by a team of biologists and linguists, led by Pavel Flegontov, a specialist in genomics, published a response to Das, Elhaik and Wexler's 2016 study, criticizing their methodology and conclusions. They argue that GPS works to allow inferences for the origins of modern populations with an unadmixed genome, but not for tracing ancestries back 1,000 years ago. In their view, the paper tried to fit Wexler's 'marginal and unsupported interpretation' of Yiddish into a model that only permits valid deductions for recent unadmixed populations. They also criticized the linguistic aspect of the study on the grounds that "all methods of historical linguistics concur that Yiddish is a Germanic language, with no reliable evidence for Slavic, Iranian, or Turkic substrata." They further describe the purported "Slavo-Iranian confederation" as "a historically meaningless term invented by the authors under review."
Alexander Beider also takes issue with Elhaik's findings on linguistic grounds, similarly arguing that Yiddish onomastics lacks traces of a Turkic component. He concludes that theories of a Khazar connection are either speculative or simply wrong and "cannot be taken seriously."
