Ashkenazi Jews are not descendants of converts. The Khazar ancestry hypothesis is basically a myth manipulated by the political interests of those who wish to delegitimize the Israelite ancestry of the biggest group of Jews alive today.
There is ample historical proof that the ancestors of today's Ashkenazim were well settled in Europe long before the Khazar kingdom fell to the Russians and Tartar-Persian armies. Furthermore, Yiddish is a Germanic, not a Turkish language, the Khazars were either Turkish or Turko-Mongolian.
There is no link from any historical or scientific matter that ties together the Khazars with the Ashkenazim. Hence, the purported Khazar ancestry of the Ashkenazim belongs exclusively to the realm of fantasy.

"A study published by the National Academy of Sciences found that "The results support the hypothesis that the paternal gene pools of Jewish communities from Europe, North Africa, and the Middle East descended from a common Middle Eastern ancestral population, and suggest that most Jewish communities have remained isolated from neighboring non-Jewish communities during and after the Diaspora." [2]. Researchers express surprise at the remarkable genetic uniformity they found among modern Jews.

A sample of 526Y chromosomes representing 6 Middle Eastern populations (Ashkenazi, Sephardic, and Kurdish Jews from Israel ...); was analyzed for 13 binary polymorphisms and six microsatellite loci. The investigation of the genetic relationship among three Jewish communities revealed that Kurdish and Sephardic Jews were indistinguishable from one another, whereas both differed significantly, from Ashkenazi Jews.

"[as this discussion is clearly full of racial-supremacists.]
only the "jews" here have expressed any supremacist views."

Firstly, why do you assume I'm Jewish?

Secondly, you're absolutely wrong. You're trying to prove that Israel shouldn't exist. If you were to do that on grounds of political reasons, I could understand. But doing it in a racial context is NOT cool, and extremely reminiscent of the ethnoracial "scientists" Germany produced in it's opening years (in the 19th century) as a country.

I want to thank you for your brilliant research. I had no idea how so many historians got it wrong!! Your premise that there was this movement called: "Jews for Hitler" is brilliant. I just have to say it over and over....."Jews for Hitler". Every time I say it.......I realize how intelligent you are. Jews for Hitler, Jews for Hitler. Hitler is jewish......so he loves jews.....I get it. You need to get a BRAIN SCAN right away! If you don't have insurance....just show the doctor some of your comments.

Hello, Jew-Hater from the Jew-Hating country! I bit of information to clerify your fogged with hate brains (if you have any): According to the newest studies the Haplogroup Q (Siberian) is present in .5% of all tested Ahkenazim. Most likely they are related to a single male ancestor which lived in the South East of the modern Ukraine around 1000 years ago. Thus, the "Khazar Theory" is only .5% true which is not statisticly signifficant. Antisemites! If you don't want to look radiculous, try to come up with something better than your obviously false "theory".

and now the end is near, weve travelled far, from perth to paisley.

Many modern Jews with the surname Cohen, which is associated with the historical Kohenim, share a common ancestor in Israel dating back approximately 3000 years, 1700 years older than the Khazar conversion to Judaism. This result is consistent for all Jewish populations no matter where they are found around the world.

Moreover, "The analysis provides genetic witness that these communities have, to a remarkable extent, retained their biological identity separate from their host populations," evidence of relatively little intermarriage or conversion into Judaism over the centuries." Id. And "Another finding, paradoxical but unsurprising, is that by the yardstick of the Y chromosome, the world's Jewish communities closely resemble not only each other but also Palestinians, Syrians and Lebanese, suggesting that all are descended from a common ancestral population that inhabited the Middle East some four thousand years ago. Id.

Modern DNA studies on the Y-Chromosome of Jews worldwide such as the Human Genome Project have determined that modern Jews share common semitic (Middle Eastern) origins dating back to a common genetic source 3000 years ago in the Middle East, presumably Israel.
A study published by the National Academy of Sciences found that "The results support the hypothesis that the paternal gene pools of Jewish communities from Europe, North Africa, and the Middle East descended from a common Middle Eastern ancestral population, and suggest that most Jewish communities have remained relatively isolated from neighboring non-Jewish communities during and after the Diaspora."

"The results accord with Jewish history and tradition and refute theories like those holding that Jewish communities consist mostly of converts from other faiths, or that they are descended from the Khazars, a medieval Turkish tribe that adopted Judaism."
