Darn! My father’s folks came from northern Finland, near Tornio. Now my doctor has me taking 1000 mcgms of B~12 daily. Coincidence!?
The pills (sublingual) allow you to bypass the gut to get the B12 "inside". Fortunately you don't need much of it. They used to give shots of this stuff once a month and some genius figured out how to make it taste like cherry juice.
Regarding Finland, they have racially different groups there. First you have your Skolt, Northern and Inari Sa'ami. Then there are people like the Pomars, then the Swedes, then the guys who call themselves Finns but are like Estonians (Suomi?). There are some others ~ there would be some Samoyads around more than likely, and finally there are immigrants from the deep souf'.
Recently the Swedes discovered Arabic and Middle Eastern immigrants appear to have a very low birthrate these days ~ it's possible their haplogroups simply don't breed well in the North. A thought along that line is that the two most common haplogroups found among Europeans and Middle Easterners are NOT found among the Sa'ami or the Saudi Arabians. Then, in India it was just discovered there are only two main lines of people ~ those who have haplogroups common among Middle Eastern Persian types and those who have haplogroups common among the Andaman Islanders. Obvious question is what happened to the others?
We all may well be designed for specific habitats. If so, and considering this place doesn't get 45 days of continual night (for example), or even 1 day for that matter, we may all be living outside our range, eating food not good for us, and suffering all the ills that befell critters who stray from their natural range.
I was just reading many restaurants in Canada are now adding seal meat to their menus. May take a visit up there!
