Crocodiles have survived for hundreds of millions of years, so why haven t they evolved to adapt to

The essence of biological evolution is to adapt to the environment, since there is a water environment, then the organisms that survive in the water will exist, crocodiles are suitable for survival in the water environment, and other terrestrial reptiles may be crocodiles, the original aquatic reptiles evolved after living on land.

Because the evolution rate of crocodiles is very slow, sometimes it takes thousands of years to evolve a little, and the evolution is still very incomplete.

The evolution of crocodiles follows an "intermittent equilibrium", and the reason why they appear to be unchanged is because they are in a period of stable equilibrium. Scientists used machine algorithms to estimate the evolution rate of crocodiles and found that although crocodiles evolve slowly, they sometimes suddenly become faster due to changes in the environment.

The Earth is a living planet, and in such a long period of time, the Earth has experienced five extinctions, and life has been constantly changing, evolving, and being born. But it wasn't until millions of years ago that intelligent life was born, and with the advent of writing, human beings officially entered the stage of civilization development. I believe that many friends who have studied the entire history of human birth, evolution, and civilization development will have a feeling that the birth of human beings is incredible.

In particular, it took only about a million years for humans to evolve into civilization, which is an incredible thing in the 4.6 billion years of life evolution on Earth. Although in the eyes of many people, a million years is a long time, it is a very short time for the evolutionary history of life.

At that time, there were not many dinosaurs, and they were the overlords of the earth at that time. Dinosaurs lived on Earth about 100 million years ago, which is a long time in the history of life on Earth for billions of years. What makes people feel strange is that dinosaurs did not give birth to intelligence, let alone form a dinosaur civilization.

So some people have a question: why were humans able to breed intelligence in just a million years, while dinosaurs lived for hundreds of millions of years but failed to do so? After this question was raised, many friends joined the discussion and analyzed the possibility of why dinosaurs did not produce intelligence for hundreds of millions of years.

Here's a summary of my friends' opinions. Everything is beautiful, survival of the fittest. Nature's creatures compete with each other, and those who can adapt to life choose to stay.

Any creature that doesn't want to be eliminated by nature can only stand at the top of the food chain.

In the age of dinosaurs, no creature was an opponent of dinosaurs, and only their internal strife could pose a threat to dinosaurs. It is important to know that the entire dinosaur community will also have competition for food and territory. One of the reasons why dinosaurs failed to give birth to intelligence may have something to do with their large physique.

You must know that dinosaurs are born with a strong physique. From birth to adulthood, there are basically no natural predators, and no creature dares to challenge the authority of the dinosaurs. But it is this innate advantage of dinosaurs that makes dinosaurs worship strength.

Do they need wisdom? As long as there is strong physical strength, any wisdom is useless. They don't need wisdom and rely on strength to defeat all enemies.

So dinosaurs don't need to think. When they were full, they went out hungry to hunt and sleep. In this case, there would be no significant evolutionary development of the dinosaur's brain.

This is also closely related to the cruel natural law of survival of the fittest. The ancestors of humans were primates, who were only in a weak position in the entire food chain of nature at that time. Primates believe that everyone knows that there is no strong physique, and the same is true of the primitive ancestors of humans.

At that time, some primates came down from the trees and began to learn to walk upright. At this time, their survival in nature is facing a huge challenge. You know, there were a lot of animals on the plains that could threaten the primitive ancestors of humans, who were completely lower in the food chain at that time.

How can you live without a strong body? So in the face of this cruel reality, human beings began to learn to think among their primitive ancestors, thinking every day about how to survive, how to avoid being attacked by wild animals, and how to find food if wild animals are caught. With constant thinking, the brain begins to develop rapidly, the brain capacity continues to increase, and the first wisdom begins to appear.

They don't move in the water all the time, so they don't change, and nature is like this, so it's very difficult for the creatures in the water to change.

Because the dinosaurs hunted food on land, when the species continued to extinct while reducing the food of the dinosaurs, only to starve to death, and the crocodile caught food in addition to land food, there is also food in the water, coupled with the slow movement of the crocodile, it feels like there is no dispute with the world, so it survives for a long time.

Because the crocodile has evolved to perfection now, it hasn't changed much.

Because the crocodile is a first-class protected animal in our country, many state workers are protecting the crocodile, so there will be no change.

That's because in the past 200 million years, there has been no serious genetic transformation, so even if there is a change, there is no way to see it.

Summary. Human potential can be stimulated, so we can also understand that the potential of animals can only be stimulated under strong pressure. The crocodile is very powerful, it is not threatened by any other animal other than the crocodile, everything it wants is at its fingertips, so it does not need to work hard, it does not need to use its brain, and it is not stimulated.

Therefore, the crocodile is like a well-fed person, very lazy and unenterprising, so it cannot evolve into a higher animal.

Hello, I'm inquiring for you here, please wait a minute

Human potential can be stimulated, so we can also understand late mating in this way, and the potential of animals can only be stimulated under strong pressure. The crocodile is very powerful, it is not threatened by any other animal other than the crocodile, everything it wants is at its fingertips, so it does not need to work hard, it does not need to use its brain, and it is not stimulated. Therefore, the crocodile is like a carefree or upright person, very lazy and unenterprising, so it cannot evolve into a high-level moving shirt.

I hope the above is helpful to you If you are satisfied with me, please give me a thumbs up

<> crocodiles exercise less and consume fewer calories, so they can survive the period of food shortage; Crocodiles eat more, such as fish, frogs, water birds, turtles, small mammals, etc., and will not die due to lack of food; Crocodiles have strong vitality, survival ability and reproduction ability, and have a large number of eggs, and some of them survived after the age of dinosaurs and continue to this day.

Tips: Swans are wild protected animals, and the protection of wild animals starts from themselves, refuses to buy and sell wild animal products, and does not interfere with the free life of wild animals. At present, the consumption of rare and endangered wild animals in society is not only a bad social habit, but also one of the reasons for the repeated prohibition of illegal hunting and killing of rare and endangered wild animals.

If there is no trade, there is no killing, and the consumption of wild animals is not eliminated, they do not belong on the table.
