What are the real racial origins of today's Jews?

What Eva Luna said about Yiddish having a German grammar with some Slavic vocabulary thrown in matches both my own limited knowledge and what many Yiddish speakers have told me. My very minimal Yiddish definitely has a very Germanic grammar; I can understand baby German, particularly in terms of pronouns and verb conjugation. (So I don’t know what we’re talking about, but I know if the subject is you, me or him.) Just as an example, Yiddish conjugates ‘to be’ as follows: Ich bin (I am), du bist (you are), er/zie/es is (he/she/it is), which is very close to the Google translator’s German Ich bin, Sie sind, er/sie/es ist. There are variable amounts of Slavic languages mixed in, depending on which regional variant of Yiddish we’re talking; the German Yiddish dialect has much less than the Polish or Lithuanian. Most Yiddish speakers can understand nontechnical German quite well; they don’t understand Slavic languages that they haven’t learned separately.

FWIW, I’m fairly typically Jewish-looking, but have been mistaken for Dutch by Dutch people, Hispanic by a whole bunch of people, and have been referred to (by my own cousins!) as having ‘an ethnic face,’ whatever that means.

These Jews ,the Lemba tribe in South Africa don’t exactly look like white caucasians.

I think my general point was well understood by most people. I was referring to the “typical Jewish look” which I guess is Ashkenazic. When people say someone looks Jewish, in America, they usually aren’t referring to the African Lemba tribe.

I should have made myself clearer.

I have always know that there were Jews in China that looked Chinese, Jews in India that looked Indian and Jews in Africa that looked African. I think that marriages and intermixing between Jews and non-Jews in those areas, however, was MUCH more accepted than Jewish/Christian marriage in France and Spain.
