Penguins are adorable and almost everyone likes them; there are also several movies that are made about these adorable tiny birds.

There are several amazing facts about these aquatic birds. It's also very interesting how they are birds and are also excellent swimmers.

Over the years, scientists have been scratching their heads to know more and more about these birds.

Their inability to fly has translated into strengths when it comes to diving, swimming, and doing all the underwater activities flying birds cannot do. Here's a fun fact about penguins: A group of penguins in the water is called a raft, but a group of penguins on land is called a waddle!

Most people know that penguins can't fly; it's easy to see. However, they actually were once flying animals!

They are an excellent example of species survival versus specialization. Science has revealed that penguins did have the ability to fly at one point in time. However, they ended up on a different path, one in which they ended up thriving underwater and among other sea creatures.

Penguins are very similar to other aquatic animals, except for one contrasting point: They do not swim. Instead, they technically paddle using their forelimbs, which can almost be compared to flying underwater.

When it comes to penguin's bodies, they are full of surprises! The actions and habits they have adapted over the years are not typical.

These animals serve as an excellent example of how evolved species interact and survive. Some scientists believe that penguins actually evolved to stay on the ground because it took them too much time to take off and make it in the air. Over time, they realized their bodies were well adjusted to the ocean.

So, penguins stopped making efforts to keep using their feathers or wings to fly in the air. Their wings proved to become excellent flippers, perfectly designed for diving around the sea.

Nonetheless, there are many different theories about these water birds, their feet, and their flippers. They have efficiently adapted to diving. Science has provided a simple answer to those theories; penguins have a lot of fat stored and very heavy muscles that resulted in densely-packed feathers. Over time, their bones adapted and became key in helping them with swimming.

Why did penguins stop flying?

According to the experts at the National Geographic Magazine, penguins adapted to be able to remain in the ocean about 1 million years ago. There are many reasons why they stopped flying and began living in the water. These reasons relate to their lifestyle before their evolution.

The main goal of a species is to determine the easiest way to survive. The best option will result in more food with solid security and safety from predators and other wild animals.

When it comes to penguins, their advantages come via their ability to swim instead of flying. A penguin will have better access to ideal diet conditions and food sources.

The fish they feed on are dense in fats and this helps them dive better. Other birds have to spend a lot of time and energy flying in order to catch their prey.

Over time, penguins ditched their ability to fly and learned how to swim. This skill helped them escape larger birds who threatened them on the ground.

As these penguins were feeding on fish and diving using their strong bones and adapted flippers, the species eventually gave up the ability to fly. Because of that, flying penguins became a rarity.

Today, all penguins in the southern hemisphere rely on their swimming or diving ability to survive. There are no penguins that rely on their ability to fly in the air. However, this theory does come with its loopholes.

If penguins had the ability to fly, their lives could have very well been made a lot easier. Flying could've saved some from having to make deadly dives, and having wings could've helped them escape water-bound predators with ease.

They could've been able to find food more quickly and without as much effort. In a sense, it goes to figure that penguins should have evolved with both flying and swimming skills.

As mentioned earlier, there are many different theories as to why penguins eventually lost their wings. If they ended up evolving with both wings and flippers, their escape from land and water predators would have been made much easier.

However, it didn't happen this way. Once the birds learned how to swim, their wings became more and more efficient in swimming.

Over time, they passed these habits on to their kids (or young). Now, after all these years, penguins cannot use their wings like other flying birds.

With time, their wings stopped presenting any sign of flight capabilities and instead became more proficient in swimming. Because of all that, even though their bodies may have been able to support the flight, penguins' wings were unable to get the job done.

Why can't penguins fly?

It is very interesting to learn whether or not a penguin can fly. The many theories that remarkably explain why they stopped flying can definitely inspire some curious thoughts.

Even the idea that penguin communities totally altered their lifestyle, transitioned from air animals to land animals, and became more reliant on their feet and flippers, is enough to pique a person's interest.

The entire process describing how a penguin completely adjusts its nature, shifting from life in the air to life on land is very similar to the same process sea animals followed when evolving to land animals, simply because they had more food options on land.

At present, a penguin's respiratory system has enough power to hold its breath underwater for over 20 minutes.

They also have dense bones that support their flippers, which were once known as wings. The penguin population lost its ability to fly when it adapted from one medium to another.

When an animal moves from one medium to another, it's a solid sign that it can no longer perform the activities accessible to them in the first medium; in the case of the penguin community, that activity was being able to fly around like a winged bird.

Why do penguins have wings if they can't fly?

In earlier times, a penguin could fly just like most birds that are commonly observed today. Over time, they adapted to their life in the ocean.

What is now called a penguin's flipper was previously used as a wing. Since their adaptation, it is now used for slicing through ocean waves and currents, and not for flying in the air.

Almost every species that evolves has a certain body part that it doesn't really need anymore. In humans, that body part is the appendix; it's an anatomical feature that humans do not need to survive.

When it comes to penguins, their wings became modified for some other use; in this case, that other use is swimming. Because of that, they don't use their wings like other flying birds do. Penguins will use their wings to dive, swim, and join other animals that live in the ocean.

Could penguins fly before?

Yes, penguins are one of those birds which started off flying, but later adapted to living on land and in the water. Some millions of years ago, it is very possible that all penguins used to fly and use their wings.

There are many different animals that have changed their medium of living; some moved from sea to land, but penguins have moved from air to sea. Due to better food and survival chances, penguins slowly changed their habitat from air to sea.

Penguins from earlier times also looked very different from the penguins that are recognized around the world today. Back then, they had less fat and their wings could still support their body mass.
