WHY don’t penguins fly?

Swimming is great, but flying is an obvious failure. This is due to the fact that their bones lack the familiar lightness of birds and resemble more the structure of humans and other mammals. The wings are also peculiar: they have no wing feathers, do not bend, and look more like a fish fin.

Some scientists still argue that penguins were once able to fly. Yet gradually, they were forced to find food in the water, and the flying function was sidelined.

In nature, as we know, everything you don’t take advantage of gradually disappears. That’s why you have to regularly strain your brain and train your ability to think!
