Interesting. I was not judging the eyes but it is about the only way the lay person can tell. If you know the family came from somewhere in Scandinavia it might be a tip. I wonder if the facial structure is slightly different. I think all those women have higher cheekbones as well.
Obviously a genetic adaptation due to the cold in the Lapp region. I wonder why people stayed that far north and if the Ice Age made any difference.
Problem with that is it has 25 times as much iron as any other mammal. So, you eat nothing but seal your body needs a way to get rid of the excess iron. I think you've seen those guys with copper colored arms underlain with iron deposits ~ probably that, and also Intermittent Scandinavian Porphyria ~ plus 82 other different main gene sets for liver function.
At these latitudes all those folks are deficient in B-12 (and some other B vitamins, but mostly B-12).
The ladies have a rounder face than people to the Souf' in Europe ~ those with a shot of Indo-European ancestry. That pronounced cheek bone is a recurrent theme though and can sometimes get out of hand ~ plus dental dysplasia (naturally missing, or extremely crooked teeth) is a hallmark. One survey found that 18% of Sa'ami had three or more natural teeth that never came in!
I have a big bunch of cousins who can pass for Skolt Sa'ami, but most Sa'ami in Europe are found in Norway and speak Northern Sa'ami language.
The Scandinavians have take two approaches to the Sa'ami over the centuries. First they tried to ship them out to America ~ and secondly they tried to force them to become good little Finns, Swedes or Norwegians.
More recently they've given up that stuff.
