Thanks for the tip about Haplogroup Q.I'll try to find out more about it.I think I read a bit about it a few months ago.Where did Doron Behar say this?Is it in the following paper?Behar, Doron, et al., "Contrasting Patterns of Y Chromosome Variation in Ashkenazi Jewish and Host Non-Jewish European Populations," Human Genetics 114, March 2004, 354-365.
I thought the European contribution to Ashkenazic mtDNA was only 60 percent (or less?) and that the non-Middle Eastern Y-DNA contribution was 10-20 percent, hence out of 200 points that's about 70 or 80 from outside of the Middle East, not the majority component because it's not greater than 100 out of 200. If I am wrong please provide specifics, from a study that you can cite. I think I saw all the studies that were published already.
I didn't look at Jewish ancestry "as purely Judean in origin", so you need to approach the other scholars and rabbis and take them to task when they make that claim, not me.As they say, don't preach to the choir.
Poland does not have "places and streets...named for the Khazars" as you claim. The notion that places called Kozar in Poland came from Khazars was debunked by linguists in the last century. And what streets? The only places I could find legitimate place-names that seem to be named after the Khazars were in central Hungary (like the village of Kazár) and along the Volga River in Russia.
There are no archaeological data for Khazars coming westward.Not even in Kiev or Hungary, where we know they lived.(I retract my statements about the "Jewish" ring of Ellend, Hungary in chapter 9 of the first edition of my book, and the Chelarevo graves in Serbia are controversial as to what they mean and where the people came from.)
