Why the Arctic is not the Arctic penguin, the Antarctic is no polar bear?

he world is big and no wonder. What if you ask the animals that live in the ice and snow? You should first think of penguins and polar bears. In the two poles of the earth, the Antarctic and the Arctic, the most famous species on the Arctic land is the polar bear, the Antarctic is the penguin.

(penguin)

These two animals can live in the ice and snow, cold capacity are very strong, why the Antarctic is not a polar bear?

First from the Antarctic continent's geographical location.

Due to changes in the continental continental plate, Antarctica and other land were completely isolated from the sea, the mainland drift, the southern hemisphere without bear, the American bears are also foreign households. However, bear animals are not good at swimming, so there is no polar bear in Antarctica.

Arctic land plate split and not separated from other continents, the original Arctic plants as the staple of the cave bear disappeared, and a thick fur, meat, and body temperature regulation, wintering and biochemistry are adapted to the cold bear in the Arctic Survived, this is the future of the polar bear.

The same is the cold area, why is there no penguins in the Arctic? The Arctic had penguins, but it was not a penguin itself, but a long animal like a penguin, whose name was a big puffin. In fact, the big puffin is the real penguin, English penguin the word: penguin, originally refers to the big puffin. Now the penguins are mistaken for the relatives of the big puffin, so we now call it penguins.

The puffin has a tragic process of extinction. It does not fly, good at swimming, but walking on the land is very slow, and even need to help wings walking, so that they usher in the largest natural enemies - human. Walking slowly, easy to capture human, but delicious meat, eggs are delicious. Humans not only pull their feathers, but also a large number of catch food, they produce eggs into a human dish. Descendants are difficult to extend, leading to the ultimate extinction.

Why is the Antarctic penguins? Penguin In addition to good at swimming, the scientists also found that a hundred million years ago, the penguin is a bird, because climate change, the Antarctic cold all year round, no suitable for growing trees, the penguins living in the tree lost the place , Gradually, penguins from the birds into today's beasts. (for your reference)

Now the climate warming, resulting in melting glaciers, are caused by humans, hoping penguins will not become the second big puffin.
