The Inuit are not First Nations, because their ancestors arrived in America much later than the ancestors of the First Nations people. In fact, the Inuit are more similar to peoples living in regions of Northern Asia.
Around 12,000 years ago, groups of hunters crossed the Bering Strait to Alaska and then moved south. These hunters were looking for caribou and they also found musk oxen. Around 10,000 years ago, these first Aboriginal peoples travelled back up to Quebec.
About 750 years ago, Inuit ancestors left Alaska and travelled to the Canadian Arctic and Greenland. They are the Thule people.
The Thule were experts at hunting large marine mammals, such as whales. They also hunted walrus, seals and caribou.
