I'd have to hang out with a ton of Japanese people for a while to be able to tell that are Japanese. I think it works with caucasions and blacks too, though. Could you really tell which country in Europe my ancestors lived in just by looking at me?

I do, but I think it's a little creepy posting pictures on the internet. Yes I do think she is cuter especially since all of her dark is also corkscrew curly!

Probably.

But your analogy only works if black people and white people retain those things that make them identifiable within their distinct ethnic and cultural groups.

For instance, I can often detect people of the Africa diaspora who have (especially more immediate) African and Carribean roots based on certain facial features. I can also detect people of Irish, Italian, German and Russian descent. However slavery, immigration and assimilation made it such that many people are unaware of their non-North American roots and/or are not easily identifiable as a distinct ethnic or cultural group.

Asians both American and abroad are more likely to retain distinct physical and cultural attributes.
