Pedantically that's incorrect. Some Inuit communities live far below the arctic circle, which technically makes them non-arctic Inuit.

Then it should only be Inuit since I'm assuming the Inuit outside of the arctic also have these ancient genes.

The title makes it seem like only the inuit who live in the arctic have these genes. But I doubt that's the case.

Since we're being pedantic, it should be pointed out that they are not all "Inuit" by any means. Inuit is primarily a term used in Canada.

In Alaska, besides the Native American tribes ("Indians") that also live in some of the same areas, there are Inupiat, Yupik, and Aleut. The Inupiat are fairly closely related in culture and language to the Canadian Inuit, but the Yupik and Aleut are considerably further apart in terms of language. Calling a Yupik an "Inuit" is sort of like calling an Italian "French" just because they both speak a Romance language. They tend to not like that very much. :-)

> In Alaska, besides the Native American tribes ("Indians")

A twist on this is that even though Native American sounds more correct (doesn't imply being from India, is longer and bureaucratic), they'd actually rather be called Indians. It helps to claim it's short for Indigenous.

For that matter, I know Inupiat and Yupik who live in Los Angeles. :-)

I think it's useful for people who are unfamiliar with who the Inuit are.

So far …
