Dinosaurs were not completely extinct, birds and even chickens are descendants of them, how do exper

Dinosaurs are Jurassic creatures that have long been extinct, and not only our country and many countries in the world have been chasing dinosaur fossils and conducting corresponding research on dinosaurs. Experts say that the dinosaurs did not completely exterminate chickens, the most common of poultry, and are also descendants of dinosaurs. This explanation also shocked everyone, because there is no way for us to associate chickens and dinosaurs.

In everyone's mind, dinosaurs are very huge creatures, and their combat effectiveness is also very strong, but chickens do not have any combat effectiveness.

The reason for the extinction of dinosaurs is that most netizens are very curious through the research of experts, probably because after the large-scale volcanic eruption, the number of dinosaurs has decreased a lot, and when the asteroid hit the earth, it led to the complete extinction of dinosaurs. Experts also said that dinosaurs were not completely extinct, like today's birds, as well as poultry, chickens are also a kind of dinosaurs, because the skeletons of chickens and birds are very similar to dinosaurs, but there has been no clear evidence for this conclusion.

In the minds of many people, they think that dinosaurs are completely different, because when we watch some documentaries, we also know that dinosaurs are very scary creatures, and dinosaurs are also very powerful. Dinosaurs are also very large, how can they be associated with skinny chickens?But with the reason of the biological chain, these creatures also need to evolve to protect themselves, and reproduction is the same as humans.

Experts are still investigating some explanations of dinosaurs, especially by searching for dinosaur fossils, which also allows us to discover more secrets of dinosaurs. And the mosquitoes that everyone usually hates have actually survived for thousands of years, which is longer than humans. Mosquitoes also appeared in the Jurassic era, the dinosaurs were extinct, mosquitoes are not extinct, and it can also be found that the vitality of mosquitoes is very strong.

Experts learned about the growth and development of birds, and the knowledge that dinosaurs were not completely extinct, and through research and investigation in this area, this interpretation was carried out.

Experts have studied birds in this area, learned about the fact that dinosaurs were not completely extinct, and explained this situation through specific research studies.

Experts say there is some basis for this, and there are some clues to prove this view, which is generally accepted.

Zhou Zhonghe, an academician of the Chinese Academy of Sciences, expressed his opinion in a public lecture that dinosaurs were not completely extinct because birds are descendants of dinosaurs. According to this theory, birds originated from theropod dinosaurs.

Whereas, the protochicken belongs to the order Ornithischia-Chickenformes. Humans domesticated the original chicken to become a domestic chicken and used it as food, and it can be said that the original chicken was also a descendant of the dinosaurs. Hu Xiaosong, a professor at China Agricultural University, made it clear in a program that chickens are direct descendants of dinosaurs.

There are also sparrows, geese, chickens, seagulls, eagles and other animals, because experts say that birds and chickens are descendants of dinosaurs, and they have similar forms and living habits.

There is a scientific basis for this statement, because this statement has been confirmed by many experts, and there is a certain regularity in the genes of the two animals, so I think this statement is correct.

There is a scientific basis for this claim, and there are many people who have investigated the matter, and there are indications that this is indeed the case.

There is no scientific evidence to prove it. So there is still a lot of controversy about this statement.

What is the scientific basis for the academician to say that the dinosaurs were not completely extinct, and the chickens are also their descendants? For now, the origin of birds is still a mystery. However, the scientific community currently agrees on the following:

Birds may have evolved from dinosaurs or have the same origins as dinosaurs. The earliest bird found so far is Archaeopteryx 100 million years ago. It lived in the era when dinosaurs were rampant.

And as archaeological excavations go deeper and deeper, scientists have also found many dinosaurs with feathers. This discovery is significant because only birds are currently feathered. Not only that, at the end of the last century, scientists discovered the Chinese dragon bird in Liaoning, China, which also caused a sensation in the whole world.

From this point of view, birds and dinosaurs are indeed inextricably linked. However, the problem arises, although scientists have found birds 100 million years ago, but birds tens of millions of years ago are still completely blank for humans. Scientists have not yet found a fossil of a bird from the Jurassic period, so where did the birds go during this time?

This may have to wait for future archaeological excavations. According to the current understanding and discovery, birds belong to the close relatives of dinosaurs. If the two are of the same ancestry, then chickens, as birds, should be considered close relatives of dinosaurs, and if birds evolved from dinosaurs, it is correct to say that dinosaurs are the ancestors of chickens.

The ancestors of chickens were carnivorous dinosaurs. Researchers at North Carolina State University in the United States have found that the protein extracted from a 68-million-year-old Tyrannosaurus rex bone is similar to that found in chickens, further demonstrating the evolutionary relationship between dinosaurs and birds. Researchers extracted a type of collagen tissue from a fossilized femur of a tyrannosaurus.

Analysis of it has shown that it is structurally similar to proteins in chickens. The ancestors of birds are early reptiles. It's true that the ancestors of chickens were dinosaurs, but it's not wrong to say that they were Tyrannosaurus rex.

The Tyrannosaurus rex branch has not survived and has long been extinct.

Every creature living on the earth can find the shadow of some dinosaurs in the ancient age of dinosaurs, not only chickens are descendants of dinosaurs, birds are also part of the descendants of dinosaurs, and monitor lizards are also part of the descendants of dinosaurs. The main reason for the extinction of the dinosaurs was one, and of course there were many secondary reasons that caused the extinction of the dinosaurs at that time. The main reason for extinction is that there are three theories through research at this stage, one is that an asteroid hit the earth and caused the extinction of the dinosaurs, the second theory is that multiple meteorites hit the earth and caused extinction, and the third theory is that a large-scale volcanic eruption caused the dinosaurs to eventually extinction.

The first theory of asteroid impact mainly appeared in the study of the Southwest Research Institute in the United States in 2007, according to the simulation calculations of researchers from the Southwest Research Institute of the United States, the overall diameter of the impact asteroid is close to 160 kilometers, mainly 65 million years ago The impact of the Yucatan Peninsula on the Mexican plate, may also be the result of the impact of the Asteroid of the Baptistina family.

The second theory is that multiple meteorites hit the earth, and a number of small meteorite craters were found in the Po crater outside India, which is 60 million years ago, so it also proves that the earth did suffer multiple impacts at that time.

The third theory is that large-scale volcanic eruptions, at the end of the 20th century, some studies found that volcanic eruptions were also one of the main reasons for the extinction of dinosaurs, because a kind of Deccan dark rock was found in the actual excavation site, the scientific name of this place name is called torrent basalt terrain, the large area of the Deccan dark rock volcano erupted, dust and sulfur dioxide were ejected in large quantities, and roughly most of the plant photosynthesis was reduced, and even led to the extinction of a lot of vegetation, and a large number of vegetation extinction reduced the amount of food for edible plant dinosaurs. The number of carnivorous dinosaurs will also decline dramatically, and due to the rapid change in climate, many dinosaurs will not survive and become extinct.

The reason for the extinction of the dinosaurs is an unsolved mystery. There are many theories, and scientists are difficult to verify. But it was the sudden and drastic changes in the environment on Earth that caused the dinosaurs to survive and eventually become extinct.

There are different theories about the cause of the extinction of the dinosaurs, some say that it was caused by the impact of a small comet on the earth, some say that the volcanic eruption caused the extinction of the dinosaurs, and some say that it was caused by the arrival of the Ice Age.

It is said that an asteroid hit the earth, causing the volcano to erupt at that time, and the dinosaurs could not accept such changes and died.
