At the time this guy lived (probably 900 AD) the Vikings, meaning Old West Gothic speaking people, were just then learning to scale up the boat hull they'd discovered in Lapland ~ which made it possible to sail in Arctic and North Atlantic Waters in the open sea.
I'd say right off hand that the guy with the far North guy wasn't Indo-European at all ~ but rather was a Sa'ami
What that means to me is the folks doing the tooth analysis forgot they are dealing with a "race" which had been living separate from other Europeans in that region for about 15,000 years and had developed some rather striking differences.
Among them were the "teeth". A Finnish study found that Skolt Sa'ami were missing 18% of their adult teeth simply because they never formed. You can find several references to this under articles containing the expression"dental displasia". Seems to me that just counting teeth would have clued them in to that one individual's identity.
It's possible these studies haven't yet caught up to anthropologists though.
see my post 44
Give those anthropologists a break. They're resting after exerting themselves over the last study they produced. You might of heard about it this week, it was in all the papers:
Women live longer, but men outsex women.
When my oldest soon needed to have his wisdom teeth pulled, we were surprised to discover that he had six. The dentist asked whether he had Esquimo blood. We know is father was 1/16 Cree indian, a Canadian tribe. Guess the Esquimos got the teeth the Sami lost. ;-)
