Did birds really become dinosaurs? Why dinosaurs turned into birds

Be.

Using molecular biology methods, researchers have further improved the feather structure of a variety of primitive birds such as Confucius birds and swallow birds hundreds of millions of years ago. The results showed that the closer the bird was to the modern day, the higher the -keratin content in the feathers. More than 20 million years ago, the molecular structure of bird feathers is exactly the same as that of living birds.

Small dinosaurs resembled birds, and many of the bird-like features often disappeared as dinosaurs grew in size. But the Megaraptor had more avian features than other small oviraptors, which defied what we had previously known. However, it is the discovery of the megaloceptor that shows that in the process of evolution to birds, the characteristic evolution patterns and underlying developmental mechanisms of different dinosaur groups are different, indicating the complexity of the evolution of avian characteristics.

Dinosaurs are very large in people's minds, and birds are very small, and no one would have thought that dinosaurs and birds would be connected.

In the 19th century, the British scholar Huxley discovered that dinosaurs and birds had many similarities in bones. After studying a large number of dinosaur and bird fossils, many scientists say that birds are not only related to dinosaurs, but also likely descended from a small dinosaur.

According to this hypothesis, some dinosaurs that were closely related to birds should have had feathers, but no fossil evidence has been found.

At the end of the 20th century, Chinese scientists found dinosaur fossils with feathers preserved for the first time in western Liaoning, and researchers all over the world were ecstatic, and the discovery of western Liaoning showed the world evidence of dinosaur feathers.

Some predatory dinosaurs gradually became smaller and more bird-like, with hollow bones and a light body, longer forelimbs, which could flapp like bird wings, and feathers grew on the surface of the body. Some of them may have migrated to trees to survive in search of predators or food, jumping and landing from tree to tree, slowly gaining the ability to glide.

Hundreds of millions of years ago, a feathered dinosaur broke away from its own species and flew into the blue sky to evolve into today's large family of birds, and scientists hope to shed light on this historical process, and with the discovery of more and more fossils, they are getting closer to fulfilling their wish.

First of all, dinosaurs don't know whether they are homeothermic or ectothermic, that is, whether they are warm-blooded animals like birds. Also, dinosaurs were a large population, not only like humans with blacks and whites, but also more widely than humans and primates like orangutans and monkeys. Therefore, it is not certain whether the bird was changed by dinosaurs.

But in terms of bone shape, it is more similar. So, each side has a reason to dial the other.

Summary. The reason why dinosaurs evolved into birds was that the climate became colder and the food was less, so large dinosaurs could not survive, and those who survived were small dinosaurs, and at the same time, in order to keep out the cold, these small dinosaurs grew a body of feathers and gradually evolved into birds.

Hello dear, the reason why dinosaurs evolved into birds is: because it was difficult for dinosaurs with huge bodies to survive, and because of the limitations of materials at that time, it was difficult for huge bodies to support life, and because of this, those small bodies were easier to survive, so they gradually evolved into small birds in a state of selection.

The transformation of dinosaurs into birds is a process of continuous evolution. Variation itself exists, and only individuals with excellent traits adapted to the harsh environment can survive! As the environment continues to change, many giant dinosaurs can't adapt, and the smaller ones can hide better and eat less, so they survive!
