a woman Quantum Physicist blog questioning, the hereditary nature (scientifically) thru gene research of the Jews, the Arabs and the Mongols.......with thought of Cayce's quote above in mind:
on the Egyptians, Solon, The Greeks , Atlantis? and the Mayans 0 Calender date. (she covers an awful lot of ground here, so I'm just copying the articles that are of interest to me......anyone can go to the home page, and start each one themselves, alphabetical articles then.
the Greeks, Minoans,Egyptians, etc.
Jewish populations therefore appear to represent an example in which cultural practice in this case, female-defined ethnicity has had a pronounced effect on patterns of genetic variation. [...]
The pattern in Ashkenazic Jews is of particular interest. Despite the common opinion that this population has undergone a strong founder event, it has a modal haplotype with a frequency similar to that of its host population (9.0% vs. 6.9%), providing little evidence of a strong founder event on the female side. The possibility remains, however, that present-day Ashkenazic Jews may represent a mosaic group that is descended on the maternal side from several independent founding events. [...]
These results demonstrate that demographic events restricted to only one of the sexes can be of considerable epidemiological significance.
Needless to say, this is an extremely interesting state of affairs, and my guess is that a lot more is known about this research than is currently available to the public. It is almost impossible to speculate about the origins of the "Founding Mothers" of a significant number of Jews, but I am reminded of an old saying that if your son marries, you lose him to his wife's family, and if your daughter marries, you gain a son. Perhaps this is naturally due to the special types of emotional bonds that are formed between women. But, of significant interest here is the issue of what it is that "bottle-necked" these groups of people.
After reading The Seven Daughters of Eve, and a host of technical papers on genetics, I finally had a look at Arthur Koestler's The Thirteenth Tribe. His theory is that the majority of modern Jews are Ashkenazim, descended from the Khazars, a Caucasian people who had converted to Judaism in the Middle Ages. For a time, Koestler's ideas were vigorously argued - even rejected - but in more recent times, his ideas have been partly vindicated. Ashkenazi Jews have a more significant admixture of Italian, Greek, and Turkish genes than of Spanish, German, or even Austrian ones as do the Separdim. This certainly connects them to the Khazars, but does not exclude mixing with the Western "real" Jews of Spain and elsewhere.
There was another issue that popped up during this period: Kevin MacDonald's work. MacDonald ascribes a genetic homogeneity to Jews postulating that Judaism is an "evolutionary group strategy." MacDonald has been generally accused of anti-Semitism and, indeed, anyone with eyes can see that Jews are like everyone else: they come in all colors, shapes and sizes. We realize now, of course, that there is a wide variation in the paternal ancestry, but that there is something truly strange about the maternal ancestry of a significant number of Jews is now quite evident.
The question then became: what is mtDNA and what, precisely, does it do?
