Answer
Examine the cladogram of whales and their ancestors presented in this video. Note that this diagram does NOT show modern whales evolving from any specific fossil form, but from the common ancestors of known fossil species and modern animals. Discuss the important difference between this view of evolutionary history, and the old view which often attempted to identify specific fossils as the ancestors of a living form.

Answer:
North American Countries
In North America, the nations of the United States and Canada own land areas in the Arctic. The only U.S. state containing land within the Arctic Circle is Alaska. In contrast, Canada’s polar regions are quite vast, encompassing about two-fifths of its entire land mass and two-thirds of its total maritime coastline. The historic residents of North America’s polar zones are the Inuits, who have made their livelihoods hunting and fishing in the harsh climate for more than 9,000 years, though many modernly work in oil fields and support villages.
European Countries
The exclusively European nations possessing land north of the Arctic Circle are Norway, Sweden, Finland, Iceland and Denmark. Although Denmark proper doesn’t lie within the polar zone, its largest self-governing overseas administrative division -- Greenland -- does. In addition to a portion of the Norwegian mainland, Norway’s Arctic territories also include the islands of Svalbard and Jan Mayen. Vikings hailing from Norway were the European polar region’s first explorers, establishing a permanent settlement on Iceland in the ninth century and a long-lived settlement in Greenland in the 10th century.
