Why are there no penguins in the Arctic? What happens when penguins are sent to the North Pole?

Why don't polar bears eat penguins? Because polar bears live in the North Pole and penguins live in the South Pole, and their habitats are located at the two poles of the earth, there is no possibility of meeting each other no matter the change of time.

Judging from the climatic conditions, the North Pole and South Pole of the Earth are quite similar. In that case, why are there penguins only in the Antarctic and not in the Arctic? This started a long time ago. About 70 million years ago, the continental map of the earth was not like this. Now Australia, Antarctica and South America used to be a whole continent. We call this continent Gondwana, and the ancestors of penguins originated from this continent.

In the long process of evolution in the past, their flying ability has deteriorated. During thousands of years of evolution, penguins have become more and more adapted to life in water. With the subsequent plate movement, the Antarctic continent was separated from other plates, and penguins were trapped on the Antarctic continent.

Arctic? Penguin?

Penguins who walk clumsily and naturally can't fly can't cross mountains and rivers to the north, so there are naturally no penguins in the Arctic. Although Antarctic penguins can't go to the North Pole, but the North Pole has its own? Penguin? . There is a word called? Convergent evolution means that in two different ecosystems, species occupying the same ecology will evolve similar structures and characteristics.

The North Pole and the South Pole are two different ecosystems, but they have similar ecological environments, so similar creatures should have evolved in the same ecological environment, and in fact there used to be a bird called the sea in the North Pole. Why did you say yes? Once? Because this kind of bird is extinct now. Previous marine habitats were located in Greenland, Iceland and Newfoundland near the North Pole. It looks like a penguin, with the same black and white clothes, the same clumsy way of walking, and it can't fly.

Remember that joke? Why don't polar bears eat penguins? In fact, it occupies the same ecology as penguins.

Our ocean is indeed the prey of polar bears.

However, the extinction of the ocean can't be blamed on polar bears, because the number of great auk preyed by polar bears is limited, and it is humans who really lead to the extinction of great auk. In fact, this result is not surprising. Think about the penguin's appearance, its meat quality, feathers and eggs. If I hadn't lived in the Antarctic continent, I'm afraid I would have been fully utilized by human beings. Use? Yes

Great auk is not as lucky as penguins, and its habitat just overlaps with human activities, so humans kill great auk to make it beautiful and warm, and the number of great auk drops sharply. /kloc-in the 6th century, great auk's lair could not be found along the European coast, but in the 9th century/kloc, great auk was officially extinct.

Transport Antarctic penguins to the North Pole.

Now that great auk is extinct, people can only focus on penguins. In any case, it is impossible for humans to kill penguins living in the Antarctic continent, so they have to change their habitat. Now that great auk is extinct, there is a place in the original ecosystem that penguins can fill.

From 1936 to 1938, two different companies introduced some emperor penguins, macaroni penguins and donkey penguins into Norwegian waters, hoping that they could establish permanent habitats here, reproduce and fill the ecological gap here, and eventually become economic birds like great auk. However, the ideal is full and the reality is very skinny. In the long years of great auk's extinction, great auk's living space has been gradually occupied by competitors, so the new penguins will face fierce competition.

The number of penguins introduced into Norwegian waters is too small, because local seabirds are always at a disadvantage in the competition.

On the other hand, the survival threat here is much greater than that of the Antarctic continent. Not only polar bears, but also arctic foxes and minks are eyeing penguins. In addition, there are many carnivorous birds that threaten the breeding nest of penguins, so the number of penguins has not increased, and it can even be said that there are almost no chicks born here.

According to records, some penguins even died at the hands of local people. Facts have proved that both penguins and great auk, from the moment of human arrival, decided that the ecological environment they occupied must be vacant, because this kind of large seabirds, which can't fly and walk clumsily, can hardly live with human beings, and only when their habitats are completely isolated from human activity areas can they win living space.
