Academician of the Chinese Academy of Sciences said that dinosaurs are not completely extinct, so wh

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.

Summary. On December 22, scientists animatically reconstructed a Shang.

In the eggshell of the dinosaur embryo fossils, and announced that this piece has.

Fossils between 72 million and 66 million years old are of the family to date.

The most complete recorded dinosaur embryo.

Dinosaur embryos are one of the rarest fossils. The big of them.

Most of the bones are misaligned and incomplete. And this dinosaur embryo.

The integrity of the fetal fossil is very good, and we can go back and forth with it.

Answer a lot of questions about dinosaur growth and reproduction.

The study. 's co-first author Huixin Ma, a PhD student at the University of Birmingham.

Say. by scientists from institutions in China, the United Kingdom and Canada.

The team of researchers announced that the egg fossil was in southern China.

Ministry of Ganzhou, Jiangxi Province found in the lower floor of the Late Cretaceous, the current museum.

It is housed in the Fujian Yingliang Stone Natural History Museum.

In the past three years, Chinese scientists have studied dinosaurs?

On December 22, scientists animated the fossil of a dinosaur embryo still in an eggshell, and announced that the 72 million to 66 million-year-old panty key fossil is the most complete dinosaur embryo recorded by science so far. Dinosaur embryos are one of the rarest fossils. Most of them have misplaced bones and are not well preserved.

And the integrity of this dinosaur embryo fossil is very good, and we can use it to ask a lot of questions about the growth and reproduction of dinosaurs. Ma Huixin, co-first author of the study and a PhD student at the University of Birmingham, said that the fossil egg, which was found at the bottom of the Late Cretaceous in Ganzhou, Jiangxi Province in southern China, and is now in the Yingliang Stone Natural History Museum in Fujian Province, announced by a team of scientists from China, British Pure Slag and Canadian institutions.

A team of scientists from China, the United Kingdom and Canada's Xiaolao Institute announced that the egg fossil was found at the bottom of the Late Cretaceous in Ganzhou, Jiangxi Province, southern China, and is now in the Fujian Provincial Chanyingliang Stone Natural History Museum. The fossil specimen is called "Yingliang Beibei" by everyone nicknamed Fan Shenchen, and it is a baby oviraptorosaur that has broken out of its shell at the end of its shell.

The 27-centimeter-long baby dinosaur curled up in a 17-centimeter-long egg fossil "Yingliang Beibei" is in a very primitive state of preservation of Wutan, and it has not been disturbed much by the fossilization for tens of millions of years, clearly showing the state of this baby oviraptorosaur when it survived. Another co-first author of the study, Associate Professor Xing Lida from China University of Geosciences (Beijing), said that the dinosaur embryo came from a batch of suspected egg fossils from Mr. Liu Liang, chairman of Yingliang Group, around 2000.

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.

Birds are descendants of dinosaurs. The chicken-goose class evolved from the true bird wing, and the professor at the Agricultural University said that the chicken is a direct descendant of the dinosaurs. In order to adapt to the changing climate, the dinosaurs gradually changed into a kind of birds.

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, so it can be said that the original chicken is also a descendant of the dinosaurs.

The feathers, feet, wings, skeletons of birds, thin necks, etc., were left behind, while academicians believed that birds and chickens were likely direct descendants of dinosaurs.

Zhou Zhonghe, an academician of the Chinese Academy of Sciences, expressed his opinion in his public class, saying that the dinosaurs were not completely wiped out. The reason why I say this is because Zhou Zhonghe believes that birds are descendants of dinosaurs, and these small animals evolved from dinosaurs. The ancestor of the bird is the theropod dinosaur, the chicken is a type of bird, and the brigade belongs to the bird subclass, and it can indeed be said that the chicken is the descendant of the dinosaur from this aspect.

If you think about it, it's not that simple. There are two interpretations of this question, one is that Miao and dinosaurs are two different creatures, and birds evolved from dinosaurs, but now they don't belong to dinosaurs. In this way, it can only be defined that dinosaurs and birds are not the same, and birds do not belong to dinosaurs, but are just the result of evolution.

The dinosaurs are extinct, and dinosaurs cannot be studied now. There is also a kind of dinosaur bird that is a kind of dinosaur, so it is said that the dinosaurs are not extinct, which is more consistent with the academician's point of view. If you say this, it will make many people think of the question, is whales fish?

Although whales live in the ocean, they are indeed mammals, while fish are oviparous, and the two reproduce in different ways. If you want to say that birds belong to dinosaurs, you need to find enough evidence.

The current chickens look very different from the primitive dinosaurs, the chickens only have two legs, while the dinosaurs have four legs. Like the Tyrannosaurus rex, which people prefer, it has two strong hind limbs, and the forelimbs are relatively thin and small, and they are tucked away on the chest. Other dinosaurs also had 4 legs, and if you have to say that chickens and dinosaurs have a relationship, you can see some winged dinosaurs, which may be very bird prototypes, because they only have two legs.

However, this is just a speculation, because the two species are similar in appearance, so people will have such thoughts, in fact, there is no particularly strict evidence.

In fact, such a statement has appeared for a long time, but it has not attracted too much attention, because the study of dinosaurs is more troublesome, after all, there are no living dinosaurs, only their fossils can be studied.

He believes that the dinosaurs were not completely extinct, because the birds evolved from the dinosaurs, and as the descendants of the dinosaurs, the preacia has continued to this day, and he believes that the Archaeopteryx has the dual characteristics of reptiles, stoves, and birds, which is a transitional type.

Because birds are the continuation of dinosaurs, the origin of birds and the flight evolution of birds are very similar to those of dinosaurs, and the environment of birds is also related to the living environment of some dinosaurs with hair.

Academician Zhou Zhonghe of the Chinese Academy of Sciences said in the program "Academician Started" that dinosaurs were not completely extinct, because birds are descendants of dinosaurs, and birds are actually dinosaurs! Whereas, the protochicken belongs to the order Ornithischia-Chickenformes.

The descendants of dinosaurs may have been birds, because they hatched and were born in a similar way, and their body forms were similar to those of their wings at rest. Zen rotten spine.

It is very likely that the children of dinosaurs are now chickens and ducks and some birds with strange sizes, and it was previously said that chickens were the most successful creatures in the evolution of dinosaurs.
