Experts found 120 million ancient beak larvae in western Liaoning? Provide the latest evidence for the origin and evolution of birds

Introduction: About the origin of life on earth Now we usually believe in Darwin's theory of evolution, the birth of the earth has a long history. However, in the early days, the number of living things on the earth was very rare, and it was only in the course of hundreds of millions of years that so many species appeared. At present, there are many kinds of species on the earth, and human beings are very curious about the origin of species, so they hope to find their ancestors for many species.

Experts found 120 million ancient beak larvae in western Liaoning? Provide the latest evidence for the origin and evolution of birds

At present, we have classified different species to a certain extent, including birds. The creatures that occupied a place on the earth in the Jurassic era were dinosaurs. Judging from the fossils found now, dinosaurs were very large individuals, and birds also appeared in that era. The current view is usually that birds evolved from dinosaurs.

Most of the birds we can see at present are relatively small, and only a few birds are large in size. Therefore, scientists have always paid more attention to the origin of birds, and many scientists are devoted to the research of birds.

Now we want to study the origin of birds mainly with the help of fossils, and infer the evolution of birds through the study of bird fossils.

Scientists from China, Switzerland and Germany have cooperated to study an ancient beak specimen from the Jehol Biota in the western Liaoning region of China, about 120 million years ago. Although the ancient beak bird grew very long ago, it was a creature 120 million years ago, but this bird was not very large at that time.

It was about the same size as it is now. And this bird has no teeth, so it can represent modern toothless birds, which can also be evidence of the differentiation between modern toothless birds and toothed birds.

Moreover, during the Cretaceous period, most birds actually had teeth. This kind of toothed birds mainly inhabited trees. A mass extinction occurred 66 million years ago. Such birds and dinosaurs went extinct together. in that era. The ancient beak bird is a kind of bird that lives on seeds. This bird mainly lives on land, so it has survived tenaciously during the mass extinction period. Most of the birds today are actually very similar to the ancient beaks.

A long time ago, many dinosaurs and birds with a lot of feathers were discovered in the Jehol biota in China. These discoveries can provide more key evidence for the origin and subsequent evolution of birds, and are more conducive to relevant personnel to conduct research.

The collaborative team recently conducted a study on the fossil specimens of ancient beak birds in the Jehol biota. Through multiple comparisons, the researchers also found that this chemical specimen should be attributed to ancient beak birds. However, the size of this batch of specimens is much smaller than that of the original ancient beak, so the researchers believe that this batch of specimens should belong to the juvenile stage of the ancient beak.

Conclusion: Through the study of ancient beaks, it was found that this bird actually has the ability to fly in its infancy, and now most birds must wait until their bodies mature and fully grow feathers before they can fly. Related research on ancient beak bird fossils also allows us to further understand the evolution of birds.
