The Native Americans that were known as Inuit lived along the northern coastline of North America and in the southern, southwestern, and southeastern coastlines of Greenland. The people trace their ancestry in the Tuli people. They are the last of the Native Americans that migrated in North America, and they came from northeastern Asia. Nowadays, these people are commonly referred to as Eskimos. The trademark of these people from which everyone knows them is their shelters. Their shelters are called igloos. They are built from precisely cut ice blocks, having a low, tunnel like entry, and small hole at the top so that the smoke can come out. Unlike most of the other Native Americans, the Inuit were strictly meat eaters, as there were not any usable plants where they lived, nor any plants would have provided enough energy for them to survive in the very harsh weather conditions of the Arctic Circle. In modern times, the mojority of these people have changed their lifestyle and have modernized, with only small fraction of them living as their ancestors. They can be found on the territories of Canada, Alaska (USA), and Greenland.
