You are way overthinking this and going down a rabbit hole of your own making. Facial features are correlated with and coevolve with other group/tribal characteristics. See the proliferation of blonde hair, tallness in the Dutch, prevalence of epicanthic folds, stockiness of bodies in colder climes, etc...

See also relatively isolated populations and how they look distinct. There are population bottlenecks, sexual selection, natural selection, etc...

Overthinking this? Rabbit hole? I've worked in the area for ~3 decades. I don't even understand what point you're making, beyond what I just said. We know facial features are correlated with population structure, but that's an "average" effecet. I'm saying we can predict/explain the high resolution details of individual face structure from genotype, which is not yet possible.

  Okay, I've read this archive of the article. I see some resemblance in the people in the photos, but I really, seriously could tell any pair of these people apart after spending about 30 seconds with them. I might think they were siblings or cousins if I didn't know better, but they are not easily mistaken for one another like "dopplegänger" suggests. But that goes to the same point, doesn't it? That we just expect this to be true, that people who resemble one another probably do because they share some genes? It seems so much as that suspicion is confirmed could have been said without the hype running all through the article and headline. https://archive.ph/Z9jMU https://archive.ph/Z9jMU

  You are on your own side quest to predict facial structure from genotype. That and perhaps intelligence agencies. Your quest makes you concerned with discerning from averages. Outside your world, people don't have to be concerned with averages. Instead, they can see multiple correlated features. Perhaps a jawline, a brow, and a hairline.
