Why do most land creatures swim, while humans need to learn to master?

This is a normal degradation, as humans no longer need to be in the water for their main survival activities. After leaving the ocean, humans evolved a new way of living on land. There is no need for gills to breathe in water, nor fins to move in the water.

The tail, which helps us to move freely in the water, has also degenerated ...... without a trace

The human body has become accustomed to being upright, also thanks to the completely different way we move in the water. The way marine animals move in the water is seen as a recumbent position. On land, however, we are standing.

If an adult, without special training (not a swimmer), rushes into the water, he will habitually maintain an upright state of movement. It's like throwing a stick upright and throwing it into the water. The mass of the stick itself maintains a reciprocating motion of water out of water and water into water under the action of inertia.

This seems to explain this: people who are drowning often go up and down. <>

And the proportion of an adult is about 30% higher than the proportion of water. In other words, if there is no specific way for us to float on the surface, we will undoubtedly sink to the bottom.

Swimming is actually a highly coordinated movement. The coordination of limbs with the torso allows us to swim in the water, creating buoyancy greater than (or equal to) the weight of the body. In addition, the posture of swimming is very similar to that of land animals, and even those of the ocean.

This is the horizontal movement we talked about at the beginning of the article.

Most animals on land, their movement in the water, their state and their movement on land, have hardly changed. Even land animals that can't swim will not sink if they fall into the water and keep running as if they were on land. This way of swimming is also known as "dog planing".

So whether humans can swim or not has nothing to do with whether they are smart or not! Humans have to be trained to master the essentials of swimming.

Because wild animals need to hunt in the water, and humans don't.

That's an instinctive need of some animals, and humans don't have it.

Because man is born on the land, and lives on the land.

It is believed that people can live on the mainland, and they do not necessarily have to be active in the water.

In fact, people can do it, but they throw it away after birth.

Because you don't need to swim to survive.

Because we don't have this nature, we can only learn through the learned.

Not all creatures know how to swim.

This is because different creatures have different abilities.

Of course, yes, they know how to swim, what to do when swimming, how to breathe, and how to breathe, and be able to overcome the natural waters.

I think it's okay, some of you are more familiar with natural waters, and you will master a variety of swimming skills, and you won't be unable to find your way because you have changed places.
