@RegularJoe I'm curious about how this might work across ethnicities. I can't point to a photo, but several times, I've noticed people from other continents who could easily be someone I know here, except they're African, or Asian, when the person I know is white, just for example. Under the expected differences in hair, eyes, etc, the basic facial structure is the same. A DNA match seems less likely in these cases.

I don't have a great answer other than of the 32 studied, these were their stratification:

Related to population stratification, among the 16 look-alike pairs, 13 were of European ancestry, 1 Hispanic, 1 East Asian, and 1 Central-South Asian.

But whether people who look close enough to perform as another, such as the "Chinese Obama" (Xiao Jiguo) I can't say.

Then there's Indonesia's former president, Joko Widodo:

It would be interesting to get the researchers to analyze their DNA.

@RegularJoe thank you! This is quite interesting. I'd forgotten about the celebrity look-alikes you mentioned. I'm not surprised the studies aren't there.
