I was under the imression there was new research published in Israel on this hotly debated topic. I am quoting from a quote made by mmiichael in
quoting from the OP text expounded by moderator AshleyD. The superquoted text's original was
published here: www.pnas.org...
Relevant here is the entire topic, but especially this quote made by AsleyD from the journal text:
"Haplotypes constructed from Y-chromosome markers were used to trace the paternal origins of the Jewish Diaspora. A set of 18 biallelic polymorphisms
was genotyped in 1,371 males from 29 populations, including 7 Jewish (Ashkenazi, Roman, North African, Kurdish, Near Eastern, Yemenite, and Ethiopian)
and 16 non-Jewish groups from similar geographic locations. The Jewish populations were characterized by a diverse set of 13 haplotypes that were also
present in non-Jewish populations from Africa, Asia, and Europe. A series of analyses was performed to address whether modern Jewish Y-chromosome
diversity derives mainly from a common Middle Eastern source population or from admixture with neighboring non-Jewish populations during and after the
Diaspora. Despite their long-term residence in different countries and isolation from one another, most Jewish populations were not significantly
different from one another at the genetic level. Admixture estimates suggested low levels of European Y-chromosome gene flow into Ashkenazi and Roman
Jewish communities. A multidimensional scaling plot placed six of the seven Jewish populations in a relatively tight cluster that was interspersed
with Middle Eastern non-Jewish populations, including Palestinians and Syrians. Pairwise differentiation tests further indicated that these Jewish and
Middle Eastern non-Jewish populations were not statistically different. 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.
Jewish and Middle Eastern non-Jewish populations share a common pool of Y-chromosome biallelic haplotypes."
I guess this is going to be a lively debate with science in it not only speculation. My wife has partly Spanish Sephardim partly Ashkenazi ancestors,
but her Ashkenazi ancestors look quite a lot like Sephardim as regards local anatomical varieties - they are tall, lightly dark-skinned and dark curly
hair. I suppose in later times Ashkenazim mingled with Sephardim in Eastern Europe as well... the stregth of religion is really interesting here wiht
all the wonder rabbis sometimes distilling the wisdom of an Indian guru from the torah and sometimes the Kabbalah,
From an identity stadpoint it would mean little if there are only four prolific grandmothers that settled in the middle of a Khazar Kingdom anyway
converting en masse. The historical heritage of mixing is more interesting to me - I think the Khazars were not at all peaceful, more like the Tartars
but not as devastating. Anatomically (there are nice examples in artists' anatomy books when you are learning to draw human faces) many Ashkenazim
here look similar to Turkic peoples of Eastern Europe, that have largely mixed into the local population - as they did in medieval Hungary. (Those
guys looked different from Ashkenazim, but consider that at a given time ther were close to a hundred Turkic tribes were registered in the middle
ages.) Turkic peoples then mixed with the native civilization building matriarchal cultures in Minor Asia, forming today's Turkish and Kurdish types.
There are stil some faces of Turkish people you could mistake for an Ashkenazi.
With so much mixing, the thing may boil down to a simpler debate on Israel. A lot of Israelis maintain that Palestinians are simply Arabs, although
research showed that actually many ancestors are sephardim. The same way, the accusation of anti-Israel people go like "You are led b Ashkenazi, and
if it turns out to be only a runaway tribe from Easter Europe (Russia and the Ukraine), you have no rights to act as aggressively here.
So what do you do in a very mixed situation? People there todays curiously remind one of a sibling rivalry, in this case we can say "buried
siblings". There could be as much genetic inheritance in the Ashkenazim in Israel as Sephardim genes in Palestinians...
For a Jew, this debate could mean we are fighting but ourselves.
I have not noticed many Palestinians clamoring for a recognition of their genes probably coming from Sephardim who neber left very far. The argument
is one-sided here. Arabs could say there that they have the right of land because while all they did was convert to Islam, they have Jewish genes.
I wonder if on-palestinian Arabs have this gene or not? This was a patrilinear research, and Jewish inheritance has not always been matrilinear - I
think that is a modern European layer.
The best would be to separate religion fom the ancestry in or thoughts and separate church and state on both sides of the Jordan. Well, intellectual
Jews and Arabs do that sometimes in their gestures, but power and social structure has been predominantly tribal. These tribes, as we have seen, are
far from being simple. The only difference will be who can cooperate with whom. I guess we won't see much of that until the summer. People tend to
polarize on that debate these days ue to astrological influences.
