If the dinosaurs are not extinct, will it evolve into a smart life?

If the dinosaurs are not extinct, will there be a type of dinosaurs that develop high IQs like us? I think the answer is clear now, it should not be ...

Strictly speaking, dinosaurs have not been extinct. Why? Because in the past two or three decades, our country has found a large number of hairy dinosaur fossils in western Liaoning. As a result, we have further confirmed these dinosaurs. One of the views made by the predecessors is: The bird is the alive dinosaur.

Dinosaurs can be said to be the most successful and most powerful type of creature in our human beings in more than 4 billion years of history. Dinosaurs are a generation of overlords. Its life can be said to be very exciting, but the life of dinosaurs is helpless. It is still extinct.

Dinosaur: "We have to rely on the asteroid for our dinosaurs. What are your humans?" The dinosaurs in the film finally said to us, do you agree and disagree?

Our earth has a history of 4.6 billion years, and the vertebrates where we are actually appeared more than 500 million years ago. The four -foot animal where we humans and dinosaurs were separated from more than 300 million years ago. We have developed in the direction of mammals. This category that develops in the direction of dinosaurs can be called crawling animals, that is, in the late Period, there are various crawled animals on the earth's land. But the crawled animals at that time could not be seen now, and they were already extinct.

At this time more than 200 million years ago, a variety of dinosaurs began to appear. There were large, small, meaty, and planting plants. In the middle of the middle of the middle of 150 million, our earth was on the earth. The land was ruled by dinosaurs until 66 million years ago.

Dinosaurs are a large family. This is the simplest watch to tell everyone that dinosaurs can be divided into several categories: the blue color on the left, including the duckbill dragon we know, called bird feet ; Yellow colors include triangular dragon (horned dragon) and swollen head dragon; red colors are sword dragons, nail dragons; in the middle are lizards, the biggest dinosaurs are called sauropus; There are the most beasts and beasts. Therefore, the degree of complexity of dinosaurs is no less than the mammals we are familiar with now.

This is an ecological restoration of our earth's land during the Jurassic. At that time, the land of the earth was very warm and humid, there was no glacier in poles, and the plants were very lush, but there were no flowers that we were familiar with. There are the largest lizards in the dinosaurs, there are sword dragons, some bird feet, and of course there are some meat, all kinds of dinosaurs.

Speaking of dinosaurs, I must ask how big the biggest dinosaurs are? The biggest animal that has survived on the land is a class of dinosaurs. According to the most accurate, there is evidence of fossils, we can say that the biggest dinosaurs are at least 40 meters long. How heavy is it? There may be dozens of tons or even nearly one hundred tons. The largest elephant with the largest elephant living on the earth is not a magnitude, and the elephant is only five or six tons weighing.

How did the giant of dinosaurs come from? It will not be so big at first, which is also a focus of our research in these years. Last year, we found that there were several small dinosaurs together in the wild in Yunnan. It was not the biggest dinosaur, but it was the biggest dinosaur's distant relative. We called its sister group. The biggest dinosaurs have evolved from these early or small dinosaurs walking on both legs.

So how did it evolve? Our colleagues who study dinosaurs have a preliminary conclusion now. Its large -scale does not seem to have many new characteristics. Instead, some original characteristics and some new features are combined. The bigger is to giant.

For example, the tooth of the scripts is relatively simple, just like the early crawled animals. Because it is relatively simple, you can cut it down when you eat it and swallow it directly, and you don't have to pass the chewing stage. This can keep it constantly eating, ensuring that it can eat a lot of food. Like an elephant different, the elephant ate grass, you need to chew, you need to take time to chew, so that it limits the amount of food it eats every day. This is a reason that hinders it that can be huge. Of course More than this reason, there are many reasons. It is the original and progressive combination of it to make the scripting foot dinosaur huge. This one is the recovery map of the late Baiji Period that is about to be extinct. The largest overlord dragon in front is more than ten meters long. Its teeth are very large and the forelimbs are very small. Now the lion and tigers must not be considered in front of it. If you want to bite it, you can bite your bones directly. Therefore, in the era of overlord dragon life, you can see other dinosaurs that eat plants, like the armor in front of it, except for several places that must be opened with nostrils and eye holes. The very thick armor covers it, which is related to the entire environment of its survival at the time. In addition, there is a corner dragon behind it.

We say how big is the biggest horny head in this world? It is more than two meters long. Someone wants to ask you how big the biggest head is on the earth's land? It is more than two meters long. However, there is a process of evolution. The picture on the right is our work in the Malaysian Mountain area of ​​Gansu in the past year. I found a small dinosaur about 100 million years ago. , Still walking with two legs. But through it, after tens of millions of years of evolution, it became a very large head in the later period, and four legs walking.

We found that a dinosaur is going to give it a name, just like you have a child to think of a name. We named it Liming Jiao Dragon. Why is this name? One is indeed in the corner dragon. It belongs to a very early dawn. In addition, my teacher, his wife's English name is dawn, it means dawn. I am also very happy in the future.

The rocks of 100 million years ago were like this. We need to know what the dinosaurs of 100 million years ago were like, and these stones could be found in these stones. In fact, we have worked there for many years and found a large number of dinosaurs. Dinosaurs 100 million years ago were living in this place. There was just a film here, and we gave it a name at the time.

Syrian Wulong belongs to the early duckbill dragon. Its head and mouth are relatively simple. After tens of millions of years, it has evolved in the era of dinosaurs. The front of its mouth is relatively flat like a duck, which can make it easier to obtain a variety of foods. What's more important is that it has hundreds of teeth on its mouth. Each side of the upper and lower jaws is tightly arranged to form a tooth plate. It can use both sides to chew food at the same time. The function of chewing food is very strong. No less than mammals living now.

In addition, dinosaurs are a very special crawling animal. Its teeth can grow lifetime and keep replacing. When we go to the wild to find dinosaurs, the easiest thing to find is the teeth of some dinosaurs. So we see that it is particularly late, dinosaurs are indeed a very complex ecosystem. There are various spiny crowns on the duck's faucet, which is empty inside, which can make a variety of sounds. In other words, some exchanges can be performed between duckbill dragons. It is already very complicated. This kind of sociality is no less than the current mammalian world.

Although Chinese dinosaur studies are said to be late, they can also tell everyone happily that there are more than 1,000 dinosaurs in the world, and there are about 300 kinds of our country. It is the country with the most dinosaurs.

Chinese dinosaur research has also experienced the efforts of generations. On the left is Mr. Yang Zhongjian, not only the founder of dinosaurs of our country, but also the founder of the entire research on the entire spine fossil of our country. My teacher Mr. Dong Zhiming, after graduating from college, he was divided into the ancient spine. Following Mr. Yang's lifelong research on dinosaur research, he was also the person who found the most dinosaur fossils in the world.

Our country's well -known Zigong Dinosaur Museum, the only world geological park in the world, which is mainly dinosaurs, and Lufeng's world dinosaur valley. It is a real Jurassic Park in the world. The contribution was built. In addition, Teacher Dong also organized a lot of international dinosaur inspection. Like Canadian Dinosaur Investigation, dinosaurs were also found in the North Pole, as well as dinosaurs of the Sino -Japanese Silk Road Dinosaur. So I am very fortunate to be a master's degree in the ancient spine after graduating from college.

Dinosaur research does not distinguish between borders. Foreign counterparts also hope to come to our country to find a variety of dinosaurs. I also have the opportunity to go to the University of Pennsylvania in the United States. Essence In the middle of this picture is a dinosaur that we discovered in the Lanzhou Basin in Gansu. We see that this dinosaur is nearly one meter long. Its single teeth are as large as bananas. The biggest teeth in the dinosaur are that the teeth of only overlord dragons in the meat dragon may be almost the same. I feel very fortunate to have witnessed the great development of dinosaur research in our country over the past two or 30 years. I also studied naming more than 20 kinds of dinosaurs. Of course, dinosaur research is definitely not a person who can do it alone.

Research on ancient biology and digitalization, especially in modern biological research, our research methods are very different. Those who engage in modern creatures can be repeated in the laboratory. We can't do it and cannot be repeated. But what happened to the research of modern creatures, especially in a large -scale time range? I am afraid that we can only know that we can do the geology of paleontology, because we have a history of 4.6 billion years in this earth. To discover.

Speaking of dinosaurs, I must ask how dinosaurs are extinct? There are many reasons, but at least one thing is relatively clear. The moment the dinosaurs were extinct 66 million years ago, there was indeed a little asteroid hit the earth, and the asteroid position is now in the position of the Gulf of Mexico. It has caused it to cause it. The environmental changes, dinosaurs are extinct.

But strictly speaking of dinosaurs has not been extinct, why? Because in the past two or three decades, we found a lot of hair dinosaurs in the western Liaoning area. After research on these hairy dinosaurs, we further confirmed a point of view made by their predecessors: birds are living dinosaurs.

Because of the research of these hairy dinosaurs, we can not only know how the bird's bones originated step by step, and how its feathers originally originally originally studied. The process of the origin of its flight was very good. This is a great contribution to our national dinosaur research to the international scientific community. In other words, tens of thousands of birds we are familiar with now are alive dinosaurs.

If the history of biological evolution is from water to land, to the air, then these live birds are no less than these mammals who are still running on land. From another perspective, there are about 30,000 four -foot animals we are living now, while there are more than 10,000 birds. Although we are most familiar with mammals, there are only about 6,000 kinds of amphibious frogs. In terms of the number of species, there are nearly 10,000 lizards and snakes. So if it is not a human, the living birds living in the dinosaur are actually watching what the earth is like.

There are also people who often ask me about this question. What if the dinosaurs are not extinct? In fact, the ancestors of all mammals have appeared in the dinosaur era, but we often say that these mammals in the dinosaur era have been living in the shadow of dinosaurs. Therefore, if the asteroid does not hit the earth and most dinosaurs are not extinct, I am afraid there will be no major development of mammals now, and there will be no human beings.

So if the dinosaurs are not extinct, will there be dinosaurs who have developed a class of creatures like us? I think the answer is more clear now, it should not be, because, dinosaurs have a history of more than 200 million years, and the birds that are living now are the branches of dinosaurs. The earth has given it for hundreds of millions of years to develop, and the intelligence of birds has not developed to the intelligence of human beings now, so it should not be.

There is also a very interesting question. We say that dinosaurs and humans are the poles of the community of life of Earth creatures. We and dinosaurs and birds have a very large similarity. There are very few things, kangaroo may be exceptions. In fact, most of the dinosaurs were walking upright with two legs, and some may be four legs. It was later walking into four legs. Therefore, people and dinosaurs are the most successful and most powerful types of creatures in the 4.6 billion years of the earth's 4.6 billion years.

Dinosaurs are not regarded as a history of 150 million years of survival on the planet. So how many history do we humans have? According to the current record of fossils, we only separated from orangutan around 7 million years ago. One of the most important features after the separation is that we can walk down from the tree. You can walk upright with two legs, and release a lot of things to do the forelimbs. It is not a sufficient condition.

After millions of years, more than two million years ago, we started using tools with both hands. This is a very big change. Of course A more complicated language. It was tens of thousands of years ago that the Homo sapiens began to appear, and then we all knew that about ten thousand years ago, human civilization began to have human civilization, and they could plant land. Thousands of years ago, there was a city and a bronze. Hundreds of years that everyone was familiar with, industry began to have, with electricity, science and technology began to develop. It seems that we human beings are greater and bigger on the one hand, and we can know natural transformation and nature, but at the same time we find another problem, as the film said at the beginning, humans seem to face the problem of extinction.

In fact, in the history of the evolution of earth creatures, it can be said that it is a very natural phenomenon, and there is no immortality. Because there are many forms of life, you can see the evolution of our earth's creatures, and the extinction is continuous, so after each extinction, you only need to give it time, and there will be new creatures.

In the past, there were five major creatures, including dinosaurs extinct this time, but the reason was either because the asteroid hit the earth or erupted by some large volcanic eruptions on the earth itself.

But now what we are facing, what is the reason why the sixth biological extinction is? According to the current statistics, the speed of the extinction of vertebrates is 50 times that of normal natural environment, and this reason is very clear, because the emergence of our human beings, the extinction caused by human activities. If you continue to develop at this speed, I am afraid that the sixth extinction we face is what may happen in the next century. Once coming, I am afraid that the first extinct is our human beings.

We now know that we humans are a community of destiny. If the extinction of dinosaurs is mainly the reason for natural choices, we humans are different. We have a big characteristic that we humans have initiative. We have the ability to choose from, and we can decide our destiny.

It is said that although we human beings have a history of just millions of years, we have such a high IQ and we have done a lot of good things, but at the same time, we do do a lot of bad things. If it is because of us These bad things have made us human beings live only for millions of years. It is really a very ridiculous and sad thing.

The history of 46 billion years of the earth, our human beings have a very rare appearance. It is said that we have experienced so much. Among our own genes, we should have a sense of worry. At the same time, there should be Consciousness, so we human humans really need to cherish and know how the environment is now. Our reason tells us what to do, but what we do is not very good. We must treat our earth well, start with our lives, and love us to protect the earth.

I think it is also very lucky to engage in our industry. This spring we have organized a Chinese dinosaur inspection. It took us two months, from Beijing to Guangdong, and returning from Guangdong to Beijing. We really walked south to find dragons. Of course, in the process, I have been thinking that the mammals and dinosaurs of our people also have a consensus of 200 million years. It is a history of 2000 million years of wind and rain. The relationship between us and dinosaurs has not broken.

The extinction of dinosaurs, if it is still forgiven, is helpless and there is no way. What excuses do we humans have? If we are really extinct, we can only blame ourselves.

Still, please pay more attention to the dinosaurs. I think dinosaurs can make us live better and make us live more exciting!
