Why is the elephant s trunk so long?

The elephant's physique grows larger and larger as it changes its environment and adapts to its own needs, so that the distance between its mouth and the grass growing on the ground increases, making it difficult to eat food on the ground. In addition, the flexibility of the body is not enough, and it is very inconvenient to move. To compensate for these deficiencies, the elephant's trunk slowly developed into what it is today.

Analyze this question from an evolutionary point of view.

Suppose that in the beginning the trunk of an elephant is as short as that of the vast majority of beings.

The elephant's food, some kind of plant, is about the same height as the elephant.

The purpose of the elephant is to eat the plant, and the plant does not let the elephant eat it in order to survive.

Elephants eat dwarf plants, and tall plants are significantly taller than the previous ones when they reproduce to the next generation.

The elephant with a short trunk could not eat the middle and tall plants of the next generation, so it was stunted or died, and was eliminated in the process of evolution, and the elephant with a flexible nose survived.

In this way, after many years of evolution, the elephant's food became higher and higher, and the trunk of the elephant became longer and longer.

Equally extreme examples are giraffes, hummingbirds. are all good examples to prove the theory of evolution. Of course, there is a kind of evolution that is not necessarily the way of light, for example, there is a kind of hummingbird and a kind of flower, constantly competing with each other to evolve, the beak of the hummingbird has grown to the point that it can only eat the nectar of this kind of flower, and this flower can only rely on this kind of hummingbird to pollinate, and each other has gone to a vicious evolution.

Instead of hands, it's not like you can grow it if you want to.

The nose was originally short.

He thinks he has to bend down every time he drinks water.

Too tired to pray to God said.

God, please let me drink water without bending down.

So God made the elephant's trunk very long, very long.

It hasn't changed back to this day.

That's why the trunks of the elephants we see now are so long!

Because the elephant's limbs are not flexible, it can only be used for walking, and there is no way to help it eat. So he evolved a long nose instead of a hand.

Have you heard a story?

That is, once upon a time, the trunk of an elephant was very short. There is a baby elephant in the herd, and he likes to ask why, and sometimes everyone doesn't know how to answer. So, no one likes him.

One day, he asked again what the fish eat, and one of the elephants replied, "You'd better ask about it." The baby elephant really found the fish and said:"Brother Eyu, can you tell me what you eat?

At this time, the fish opened its mouth and bit the trunk of the baby elephant at once, and the baby elephant stepped back hard, pulling the trunk so long, so long, fortunately, the baby elephant escaped. He returned to the elephant herd. The other elephants laughed at him at first, saying that his nose was too ugly, but later they found it easy to use.

So he came to ask the baby elephant how his nose had grown, and the baby elephant told him what had happened. When everyone heard this, they came to look for Eyu. That's it.

One by one, the trunks of the elephants were elongated.

Got it. This is just a children's story. )

Because Crayon Shin-chan often sings like this Elephant, Elephant, Why Is Your Nose So Long?

In fact, in the past, the trunk and height of the elephant were not as long and tall as it is now, and the elephant became larger and larger with the change of the environment and the need for its own adaptation to the environment, so that the distance between the mouth and the grass growing on the ground was farther away, and the nose gradually lengthened in order to survive.
