Why can't penguins live in the North Pole?

The results of paleontological research show that penguins appeared in Tertiary as early as 50 million years ago, and it was found that penguins once lived in the Arctic, because an extinct bird skeleton was found in the Arctic, which was called "Big Penguin".

This "big penguin" is about 60 cm tall, with a brown head, black feathers on the back and a white abdomen. They are as clumsy as other penguins when walking on land, but they are also good at swimming in the sea.

"Big Penguins" are mainly distributed in Europe, Scandinavia, Asia and North America, and some islands in the Arctic Ocean, with a number of one million. However, three or four hundred years ago, Europe set off an upsurge of exploring the Arctic. With the arrival of explorers and immigrants, the "big penguin" has become the object of contention, and its number has dropped sharply. When the last "big penguin" was killed, there were no penguins in the northern hemisphere. This is why penguins can't live in the North Pole.

Penguin is a kind of flightless bird, belonging to the genus Penguinidae.

Penguins mainly live in the southern hemisphere. At present, there are 17 or 18 species of penguins in the world, most of which are distributed in Antarctica. Among them, Humboldt penguins, Magellan penguins and black-footed penguins are distributed in temperate regions with lower latitudes, while Galapagos penguins are closer to the equator. Only emperor penguins and Adelie penguins live completely in the polar regions.
