Can Penguins Fly Like Other Birds?
Many species of living creatures have changed in size, shape and habits and are today quite different from what were thousands or millions of years ago. Penguin, is one such variety.
According to the results of researches and studies, the penguin that lived in prehistoric times was six feet tall, and could fly like any other birds. Today out of the 17 species of penguins, the largest ones called the emperor penguin is just about one metre tall and weighs about 36 kgs. The wings of the penguins are now short flappers and are useless for flying.
Why did this happen to penguins? According to one explanation the reason is that the penguins had very few enemies. They lived in the quiet remote areas in the Antarctic regions where there was practically no other creature who could attack them. They lived happily on land and water without fear. They did not use their wings for generations and the wings slowly became very small and stiff and useless for flying.
The penguins are great swimmers and divers. They use their wings for swimming instead of for flying! Since they live in very cold climate, they have a thick coat of fat to protect them from cold.
The penguins are famous and are loved for their comic looks. They stand straight and stiff on two legs, flat – footed. When they walk, their movements and manner seem so formal and stiff that it looks comical to the human eye. They often arrange themselves in regular files, just like human soldiers. Their plumage is made of small, scale like feathers and it looks as if they are wearing a black coat with a white shirt inside!
