Ah yes, the now infamous Elhaik study.
Did you actually READ what that genetic study says?
Because the only thing it proves is that Jews are genetically similar to
modern day inhabitants of certain near-east countries, many of which the author erroneously calls "Slavic" and "Caucasian." Hungary has never been a Slavic country. Armenia was not considered "Caucasian" until there were no more Armenians left alive Turkey.
The modern day inhabitants of all those countries, which lie north of the Levant, were themselves subject to waves of Middle-Eastern migration...which means that a middle eastern haploid group could just as easily have moved up into that area and then become endogamous (

In fact, that paper clearly DISPROVES the most extreme version of the Khazar theory, which claims that Jews have NO middle-eastern ancestry -- as they clearly do.
The link between Jews and the middle east has been shown time and time again.
For example, it has been shown that Ashkenazi Levites, who claim common descent from Aaron, did in fact have a common near-eastern ancestor.

Google Khazar-Ashkenazi theory and see for yourself whether or not the majority of academics agree with it. Because I can guarantee you the answer is no.
