A little research tells you that, for example, Ashkenazi Jews and Sephardic Jews are both "Jewish." However, whereas Ashkenazi Jews often hail from Europe, Sephardic Jews often hail from the Middle East. People of many different races have become Jewish over the centuries. So no, they don't share a common ancestry.

Sephardic Jews don't "often" hail from the Middle East or Africa, and neither do Ashkenazi Jews "often" hail from Europe, that is their very definition- Sephardic Jews are Jews from the Middle East (Not including Israel, of course), or Africa, and Ashkenazi Jews are Jews that come from Europe. Sorry if I'm being anal on the wording. All Jews (Non-converted) do share a common ancestry, as all are descended from the "Hebrews", which had spread all over the world due to their exile from ancient Judea by the Romans. (A disaspora)

Sorry about the wording, I should have said that I was quoting there, those weren't my words exactly. The thing is that, common ancestry is not required to be a Jew. I was saying that they don't share a common ancestry because you can be a Jew no matter where you're from. When people talk about Jews being a race, they can't exclude the ones who are Jewish because they converted, they're still Jewish. I know that you're not exactly saying that they're a race, but still, if we were talking only about non-converted Jews, their race would be Caucasian 'cause that denotes the physical type of the population of that region.

Caucasian it wouldn't be, because of the Sephardic side- Black Jewish people from Ethiopia, and very dark skinned-slight dark skinned from the Middle East. So you can't define all Jews as one skin color. :) I know what you're saying, but that's why I said that all *non-converted* Jews share a common ancestry.

The term Caucasian in common use is used when referring to light-skinned people, or what you would call white people. But, historically, it describes the entire population of Europe, North Africa, the Horn of Africa, West Asia, South Asia and Central Asia, without regard to skin tone. In physical anthropology there would be differences, as one group would be Aryans and the others would be Semitic, even though those are considered as races, they're subdivisions of the Caucasian race. All non converted Jews share a common ancestry, but, like I said, common ancestry is not a requirement to be a Jew, so Jews in general don't share a common ancestry and that is why they're not a race. If they were a race, no one could convert and be Jewish.

I do not go into these matters of whether or not Jewish people are a race. :) I was just saying that non-converted Jews share a common ancestry, that's all. In regards to the term "Caucasian"- Well, I was referring to the modern meaning of it. :) But I do believe it doesn't include all of Europe or that you said. The word comes, obviously, from the Caucasus. That is, a region of Europe but not ALL of europe, and also a part of Asia. Of course, I'm not an expert, could be wrong.

I mentioned that about the race 'cause I've always been talking about Jews in general, not just non-converted Jews, but I know that you never said if you think they're a race or not :) The part about "entire population" wasn't in reference to Europe, it was to emphasise that it's regardless of the colour of their skin, that was a bit ambiguous from my part.
