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.
-
The academician said that the dinosaurs were not completely extinct, and his scientific basis is as follows.
1. The origin of birds is theropod dinosaurs
Zhou Zhonghe, an academician of the Chinese Academy of Sciences, expressed the view that dinosaurs were not completely extinct in an open class, saying that the ancestors of birds were theropods, and the protochicken was a kind of bird subclass-chickenformes. Humans domesticated hens into domestic chickens as food, so eggs are similar to dinosaur eggs.
In the 19th century, some foreign researchers found that the bones of dinosaurs are very similar to the bones of birds, so birds are likely to be descendants of dinosaurs, but there is no evidence. More than 30 years ago, scholars in our country discovered a structure similar to the feathers of chickens and other birds in the continuous excavation of dinosaur fossils, so people associated it with theropod dinosaurs.
But Academician Zhou's statement did not provide sufficient evidence, because so much time had passed, and he did not have any evidence to prove his speculation.
Second, the evolution of dinosaurs may have gone in two directions
Let's take the Tyrannosaurus rex as an example, the size of the tyrannosaurus rex did not become smaller in the process of evolution, but from the beginning of the small and delicate, to the later larger and larger size, the hair on the body also changed from hair to scales. This suggests that the branches of dinosaurs evolved in different directions, but it is likely that only one branch evolved into birds.
This evolution led to the well-known Archaeopteryx, which was originally thought to be the ancestor of birds, but is now thought to be a small theropod dinosaur, which is not an avian ancestor, but most likely an ancestor of a later dinosaur. It also lived in the early Jurassic period of the Titun Order, about 155 million to 155 million years ago.
3. Controversy
Whether Archaeopteryx is the ancestor of dinosaurs or birds has been debated in the scientific community until now, so the academician's statement represents only one side of the scientific opinion, and the real results need to be supported by rigorous fossil evidence.
-
Dinosaur fossils that have been excavated over time have found filamentous structures that resemble the feathers of chickens and other poultry, and can only be rationalized based on the available evidence. There is not enough scientific evidence.
-
Birds and dinosaurs are similar in form, hatch and birth in the same way, birds and chickens are similar to dinosaurs, and the limbs, long tails, and huge bodies are similar, so academicians say so.
-
It is because in the process of research and investigation that birds are likely to be descendants of dinosaurs, and birds originally belonged to theropod dinosaurs, and this fact can be discovered by feathered dinosaurs.
-
The academician of the Chinese Academy of Sciences said that the dinosaurs were not completely extinct, and the current dinosaurs actually look the same as chickens, in other words, chickens are the descendants of dinosaurs, and birds are also descendants of dinosaurs. Everyone should be very shocked when they see this news, it turns out that each of us has eaten dinosaurs, and I feel a little powerful when I think about it. In fact, as early as the 19th century, foreign scientists found that the skeleton of dinosaurs is very similar to the skeleton of birds, so birds may also be descendants of dinosaurs, but there has been no evidence.
When it comes to dinosaurs, the first thing that comes to everyone's mind should be various large dinosaurs such as Tyrannosaurus rex, these dinosaurs are basically carnivorous dinosaurs, but the attack power of each dinosaur is very strong, if we see them in real life, we can't escape at all. In the past, I thought that dinosaurs were estimated to be extinct, but the academician of the Chinese Academy of Sciences said that dinosaurs were not completely extinct, and now dinosaurs look the same as chickens, or chickens are descendants of dinosaurs. <>
In addition to chickens are birds, which originated from theropod dinosaurs, while protochickens belong to the order Bird's subclass Chickens. As early as the 19th century, there were scientists who had similar studies and discoveries that there was no clear evidence at that time, but in 1996, they published the research results of the original Chinese dragon bird. This is also the first time that fossils of feathers have been found on dinosaurs, so the idea that birds are descendants of dinosaurs is well known and accepted.
Whether it's birds or chickens, it's something that everyone can't imagine, because everyone thinks that these two things are probably not related to each other at all, but we have to know that species evolves, so what it evolves into, none of us know. <>
With the change of time, it is estimated that many things will evolve into what we can't imagine, when everyone sees that birds and chicken ribs may be dinosaur Houyi, everyone first feels more shocked, and the other is to feel that they are more powerful, after all, each of us has eaten dinosaurs, I hope you can be careful when handling chicken food, and cook these things to avoid some bacteria in it.
-
Some of today's birds are all descendants of dinosaurs, birds originated from theropod dinosaurs, and the original chickens were also descendants of dinosaurs.
-
The academician published his argument because birds were derived from theropod dinosaurs, and the original machine belonged to the subclass of birds, but it was domesticated by humans, and these chickens became domestic chickens, and as food, it can also be said that the original chickens were descendants of dinosaurs.
-
Bird things, such as chickens, are derived from the horned dinosaurs, which are creatures that evolved from dinosaurs, so that the dinosaurs are not extinct.
-
We are not professional biologists, so it is really difficult to associate chickens and dinosaurs, but after reading the data of relevant researchers, we have to say that we believe that chickens are also descendants of dinosaursThis is also the first time that relevant researchers have found evidence that birds are descendants of dinosaurs, so now the view that birds are descendants of dinosaurs has begun to be accepted by everyone, simply put, birds originated from theropod dinosaurs, and protochickens belong to the order Otrichiformes, so chickens are also descendants of dinosaurs.
Academician said that chickens are also descendants of dinosaurs caused a lot of heated discussions, to be honest, many people feel very incredible about this statement, because chickens and dinosaurs have no similarities in terms of size and characteristics, we can't combine the two, and we can't believe that chickens are the descendants of dinosaurs, dinosaurs are a very sacred animal for us, dinosaurs were the overlords of the earth, and later dinosaurs died out for various reasons, The latest data shows that dinosaurs are not completely extinct, because chickens are also descendants of dinosaurs.
At first, I didn't agree with this statement, and I think it's nonsense at all, this problem is indeed a bit complicated to explain, birds originated from theropod dinosaurs, and the protochicken belongs to the bird subclass - chickens, chickens become poultry after being tamed by humans, and birds are descendants of dinosaurs, so chickens also belong to the descendants of dinosaurs.
After many centuries of changes, it is now certain that chickens are indeed descendants of dinosaurs, which means that dinosaurs are not completely extinct, the age of dinosaurs is a long way from us, and they have undergone a long period of evolution and transformation before becoming the overlord of the earth, so do you believe that chickens are descendants of dinosaurs?

The academician said that the dinosaurs were not completely extinct, and the chickens were also descendants of the dinosaurs, and I agree with this statement.
Our current era is already an era when a person can coexist peacefully with nature, which is the joint efforts of several generations of our people, and we may also understand the things of ancient times through the present, when the world was ruled by dinosaurs, but it was just the size of a mouse, but then the dinosaurs were exterminated and then gradually rose, but now there are academicians of the Chinese Academy of Sciences who say that the dinosaurs are not completely extinct. The chickens that we commonly see in our daily lives are also direct descendants of dinosaurs.
According to some reports and the accounts of these experts, I think this point of view is actually correct, although it seems very ridiculous, that is, through some research and investigation, it has been shown that birds are actually a kind of descendants of dinosaurs, birds are a kind of theropod dinosaurs, and chickens are also a kind of bird birds. According to the documentaries and some records in history books that we often see now, we know that there are many kinds of dinosaurs, and dinosaurs are also divided into avian dinosaurs and flying bird dinosaurs, if there are really avian dinosaurs, we can understand that chickens are really descendants of dinosaurs, because they can change their form in continuous evolution, in the continuous advancement of nature, not only these animals are constantly evolving, we humans are also constantly evolving into human beings, Therefore, when the experts of the Chinese Academy of Sciences put forward this point of view, I was very convinced, because it was relatively theoretically supported.
This incident is actually an inevitable result of the evolution of human beings and various species in the world, and now this society can be said to be a society ruled by humans, and animals such as chickens have also been domesticated by people. Now is the era of human beings, but we still do not rule out that in the original era of dinosaurs, there were still some dinosaurs that did not go extinct, and the dinosaurs did not go extinct to mankind.
-
I agree, because the academicians of the Chinese Academy of Sciences discovered this phenomenon in the process of careful research and investigation, because chickens belong to the bird subclass - chickens, and then birds belong to theropods, and these belong to the descendants of dinosaurs.
-
I agree that this result is because the academician came to this result based on careful research, and the descendants of dinosaurs are not only chickens but also birds, because the earliest dinosaurs of the horn type of birds are the first.
-
I disagree with this statement because I think they are two different species of animals.
-
The extinction of dinosaurs has been a long time ago, and everyone can only use their imagination to make bold assumptions, and if you want to have more theoretical basis, you still need to continue to experiment. After such a long period of evolution and development, birds must also have different forms, and the skeletons of Archaeopteryx and dinosaurs are very similar, so everyone will make reasonable guesses.

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.
-
It may be that scientists have found some similarities between chickens and dinosaurs after research, and both belong to the same subclass species. That's why it's believed that chickens are descendants of dinosaurs, and not only chickens, but birds are also descendants of dinosaurs.
Did the dinosaurs go extinct? The bird is not its descendant. 66 million years ago, due to a mysterious catastrophe, the dinosaurs suffered a catastrophe.
Scientists accurately determined that the dinosaurs became extinct 65.95 million years ago The extinction age of the dinosaurs was a transitional period between the Cretaceous and Tertiary periods, which fluctuated up and down for about 40,000 years 65.95 million years ago. The date of the extinction of the dinosaurs has been determined much more accurately than before.
If the dinosaurs were not extinct, then they would definitely be a very terrifying and magical existence for humansAnd it is definitely possible that it will evolve into a phobia, after all, living things are constantly evolving in order to live a better life. <> >>>More
If it weren't for the meteorite impact, the dinosaurs would have survived, and humans might not have appeared, and they would have evolved intelligence. Therefore, as shown in film and television works, there will be no scenes of human wars with dinosaurs, because primates did not appear until the late Cretaceous period, when it can be said that primates were very weak, not very large and did not have an advantage against dinosaurs, and most of them were cruel carnivores. >>>More
