Stampfer, an expert in Jewish history, analyzed material from various fields, but found no reliable source for the claim that the Khazars – a multiethnic kingdom that included Iranians, Turks, Slavs and Circassians – converted to Judaism. “There never was a conversion by the Khazar king or the Khazar elite,” he said. “The conversion of the Khazars is a myth with no factual basis.”The claim that Ashkenazi Jews descend from converted Khazars received wide attention after the publication of Shlomo Sands's controversial book The Invention of the Jewish People in 2008, which argued for this conclusion. For reviews etc. see here and follow the links.
As a historian, he said he was surprised to discover how hard it is “to prove that something didn’t happen. Until now, most of my research has been aimed at discovering or clarifying what did happen in the past … It’s a much more difficult challenge to prove that something didn’t happen than to prove it did.”
That’s because the proof is based primarily on the absence of evidence rather than its presence – like the fact that an event as unprecedented as an entire kingdom’s conversion to Judaism merited no mention in contemporaneous sources.
“The silence of so many sources about the Khazars’ Judaism is very suspicious,” Stampfer said. “The Byzantines, the geonim [Jewish religious leaders of the sixth to eleventh centuries], the sages of Egypt – none of them have a word about the Jewish Khazars.”
Second, Prof. Steven Weitzman e-mails to alert PaleoJudaica to some relevant biological research:
May I call your attention to the following just published special volume of the journal Human Biology, which contains some very new genetics research of potential interest to your audience (including research bearing on the Samaritans, on the Khazar theory of Jewish origins, and other pertinent topics).Here's the TOC of the issue:

The scientists involved, including colleagues at Stanford, are considered leading population geneticists and their publication reflects research only possible in the last 5-10 years (though there may be more they can learn from the relevant historiography). The volume represents an attempt to bridge between Jewish Studies and genetics, and the experience has taught me that the two fields still have much to learn from the other.
Table of ContentsSome of Professor Weitzman's other work has also been mentioned in posts here and here.
