What is the reason why the trunk of an elephant has evolved so long?

The reason why the trunk of an elephant is so long is because the ancestors of the elephant themselves lived in the water and used their trunks to protrude out of the water to breathe; Elephants are tall and have a hard time getting food, and in order to survive, their trunks get longer and longer. This is in line with Darwin's theory of evolution, where elephants have longer snouts in order to survive and adapt to their environment.

1. Characteristics of elephant trunksThe trunk of an elephant is very long, and the trunk length of an average adult elephant is almost equal to the length of the body. Moreover, the trunk of the elephant is cylindrical and stretches freely. In addition, the elephant's trunk is all made up of muscles, its nostrils are open at the end, and there is a slight bulge at the tip of the nose to pick up food.

The elephant's trunk is very agile and can pick up not only objects weighing up to 1 ton, but also small peanuts and fruits on the side of the road.

2. The Evolution of the Elephant's TrunkThe elephant's trunk is getting longer and longer over a long period of evolution. The elephant is the largest mammal on land, it is a herbivore and is very fond of eating grass. From the past to the present, elephants have evolved to grow taller and taller in order to resist the attacks of predators.

And its head is farther and farther from the ground, and it has to eat grass with its mouth, so gradually, the elephant's trunk will grow longer and longer, so that it can use its nose to eat.

3. The ancestors of elephants liked to stay in the waterThe ancestors of elephants liked to stay in the water, and when the elephant was in the water, it would stick its long trunk out of the water to breathe. The trunk of the elephant's ancestors itself is not very short, and the role is to breathe by diving. Through a long evolution, the elephant has become taller and taller, needs to bow its head to graze, and has become more and more adapted to life on land, and its trunk will become longer and longer.

Therefore, the trunk of the elephant is getting longer and longer, in order to better adapt to life and reproduction, which is also in line with the principle of natural selection and survival of the fittest. Dear readers, do you know why elephants' trunks are so long? If you think this article is well written, please give it a thumbs up.

Because elephants are relatively large, they eat with their snouts longer and longer in order to maintain their balance, so that it is easier to eat food.

It is the reason for the survival of the fittest, so that the trunk of the elephant has evolved so long, if it does not evolve a little longer, the elephant will not be able to survive at all.

Because elephants are the largest mammals on land, they are too large and inflexible, and their limbs can only be supported on the ground, so they naturally need a limb that can be used flexibly.

Why is the elephant's trunk so long, interesting science.

The elephant's long trunk is the geological period in order to resist the harsh natural environment and the attack of natural predators, the elephant is getting taller and taller, in order to adapt to survival, the elephant's upper lip slowly becomes longer, and as the upper lip lengthens, its trunk also becomes longer and longer. The elephant's trunk is a combination of the upper lip and the nose, and a pair of nostrils like two parallel snake tubes extend from the base of the nose down to the tip of the nose. While the mouth is eating, the nostrils take on most of the breathing work.

The elephant's long trunk is the geological period to resist the harsh natural environment and natural predators, the size of the elephant is getting taller and taller, in order to adapt to survival, the elephant's upper lip will slowly become longer, with the extension of the upper lip, its trunk will also become longer and longer. The elephant's trunk is a combination of the upper lip and the nose, and a pair of nasal cherry chain holes are like two parallel snake tubes that extend from the base of the nose to the tip of the nose. While the mouth is eating, the nostrils take on most of the breathing work.

In order to resist the harsh natural environment and the attack of natural predators, elephants are getting taller and taller, but their beaks are getting farther and farther from the ground. Elephants are grazing animals, and in order to survive, the elephant's upper lip slowly becomes longer and longer, and as the upper lip lengthens, its trunk grows longer and longer.

Their main external features are a flexible and muscular proboscis and large flapped ears, which have the function of winding and are powerful tools for self-defense and feeding.

The length of the nose is almost equal to the length of the body, cylindrical, and it is freely extended; The trunk is made entirely of muscles, with nostrils opening at the end and finger-like protrusions at the tip of the nose that can pick up objects, and the trunk is very flexible and can pick up objects weighing up to 1 ton, as well as small foods as small as peanuts.

The long nose of course evolved from the short nose. According to the theory of natural selection, the trunks of elephant ancestors became longer and longer because long trunks had an advantage for their survival.

1. The elephant's trunk also has a function that is not usually used. The elephant sometimes has to cross a river or lake, and then it walks at the bottom of the river or lake, and even if the river or lake is so deep that it is submerged, it will not be difficult for it, because it can put its nose out of the water to breathe, like a snorkel. In fact, the elephant is also a master swimmer, and it can swim for hours, and it would not have to use such a stupid method to cross the river, which seems to reflect some kind of instinct of it.

2. The elephant's physique is getting bigger and bigger with the change of the environment and the need to adapt to the environment, so that the distance between the mouth and the grass growing on the ground is getting bigger and bigger, and it is difficult to eat the 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.

The long trunk of an elephant is the result of natural evolution. In order to resist the harsh natural environment and the attack of natural predators, the elephant's body grows taller and taller, and its mouth is farther and farther from the ground, in order to obtain food, it has to rely on its nose to pick up, and slowly its nose becomes longer and longer.

Animals like elephants must have evolved in food and height.

Because it is necessary to adapt to the new environment, and also for the convenience of feeding, the trunk of the elephant is so long.

Because it is to adapt to the living environment, the nose is very long.

Why is an elephant's trunk so long.

Elephant, elephant, why is your trunk so long?

Step by step! A refrigerator door opens! The second is to put the elephant in it! Three refrigerator doors closed.

Hey.. Silly baby.

Because my mother said that a long nose is called beautiful!

Because you're a crayon Xiaoxin, hehe.

Is there a story you've ever heard?

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 what to do. So, no one likes him.

One day, he asked again, what does the fish eat, there is an elephant Tao, you better ask the fish Qiaonian. The baby elephant really found the fish and said:"Brother Eyu, can you tell me what you eat?

Eyu said"Come close to me, and I'll tell you what I eat. "The baby elephant really passed.

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 the baby elephant and asked him how his nose had become longer, and the baby elephant told him what had happened. When everyone heard this, they all came to find Eyu. That's it.

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

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

Or maybe it's its genes, just think about why people have 5 senses, why do they have hands and feet.
