Greenland may have been inhabited for 5000 years, but that does not mean they share a genetic heritage back that long.

The Thule people, from whom modern indigenous Greenlanders descend, originated around 1000 CE in Alaska.

I'm pretty sure the Inuit diets in Alaska and Greenland are pretty similar though, at least in terms of macronutrients (i.e. a lot of fat).

The diets are the same and the Alaskan Inuit also carry the SI deficiency alleles.
