‘Jews a Race’ Genetic Theory Comes Under Fierce Attack by DNA Expert

For years now, the findings of Ostrer and several other scientists have stood virtually unchallenged on the genetics of Jews and the story they tell of the common Middle East origins shared by many Jewish populations worldwide. Jews — and Ashkenazim in particular — are indeed one people, Ostrer’s research finds.
It’s a theory that more or less affirms the understanding that many Jews themselves hold of who they are in the world: a people who, though scattered, share an ethnic-racial bond rooted in their common ancestral descent from the indigenous Jews of ancient Judea or Palestine, as the Romans called it after they conquered the Jewish homeland.
But now, Elhaik, an Israeli molecular geneticist, has published research that he says debunks this claim. And that has set off a predictable clash.
“He’s just wrong,” said Marcus Feldman of Stanford University, a leading researcher in Jewish genetics, referring to Elhaik.
The Ashkenazi are descendents of central-Asian Khazars who converted to Judaism about 800 AD. Then Khazaria fell and the Khazarian Jews migrated northward into Russia and westward into Europe.

Based on the state of some of the posters on here, DNA appears to be succeptible to all sorts of inaccuracies.
