Our modern poultry chickens evolved from dinosaurs, what is the evolution process of birds?

Our modern poultry chickens evolved from dinosaurs, and the evolution process of birds is as follows.

OneArchaeopteryxIt is the earliest bird

In the Jurassic. During this time, 11 fossils of Archaeopteryx were found at the bottom of the German lagoon, the earliest known bird fossils and the ancestors of birds. Over the next 84 million years, many ancient birds lived on the planet with other dinosaur relatives, who evolved teeth, claws, and long bony tails.

Sixty-six million years ago, an asteroid collision led to a widespread extinction: dinosaurs on Earth, pterosaurs in the sky, plesiosaurs in the ocean.

and other animals, and many other creatures that are almost extinct. But some birds survived and survived.

Second, there is a significant increase in birds

In the evolutionary history of birds, there have been three significant increases in the net percentage of adult species.

The first period was 165-135 million years ago, and with the accelerated evolution of anatomical modules, the increase of morphological differentiation and the spatial changes in morphology suggest that the basal bird had experienced an adaptation radiation and was in a different niche from its progenitor group.

The second period was 90-55 million years ago, and 70-65 million years ago there was a significant decline and subsequent rapid recovery. At the beginning of this stage, the morphological evolution of the cranium of the crested birds was significantly accelerated, suggesting that the irradiation in this period was different from the first time, which may be due to the diversity of feeding and feeding patterns.

The third period was between 40 and 45 million years ago, because only a small number of crested birds were used for morphological support in the analysis of the rate of morphological evolution.

3. The extinction of birds in modern society

Among the extinct birds on many islands around the world is one of the largest land birds, the largest ever on Earth. For example, Madagascar.

A flightless bird that can reach up to 3 meters in height. Another example is New Zealand.

There are more than a dozen species of moa in the archipelago.

Many of them are huge birds.

At first, they originated from flying dinosaurs, and at first they were very large, but with the change of the times, they slowly reduced their size in order to survive better.

I think it evolved from dinosaurs, the way the birds feathers are arranged, the rudiments of the wings appear on the dinosaurs; Some follicle fossils, as well as tissues such as muscles and blood vessels, are studied.

The process of evolution has gone through a long time, through many stages of development and changes in form and state, and there have been many changes.

There is no such thing as evolution. Because the ancestors of birds are birds. Dinosaurs are dinosaurs. There is no such thing as a transition species, such as reptiles to birds. The reason is simple:

1.Evolution is the upgrading of a series of traits in living organisms, and to achieve this, the genome needs to produce new, functional genetic information, and this new genetic information should be achieved overnight, because the long combination can only consume the energy of living organisms, and the result is not partial elimination, but the extinction of species.

2.The unique structure of birds is complex and sophisticated, and it is unlikely that it was formed through a long process of transition. Let's say:

feathers, which bear no resemblance to reptile scales; The lungs, the lungs of birds, are specially designed for flight, which can avoid the influx of air during flight, which cannot also be formed by slow transition, and the lungs of an organism mutate, which directly affects its survival.

3.There is no evidence of any transitional species. From reptiles to birds, if there is evolution, there must be a large number of intermediate species that have been eliminated, but in fact, there is no evidence!

There was only one fossil of what was called Archaeopteryx, but brain scans confirmed that it was 100% bird. And the presence of claws at the wing tips is not evidence of evolution, as modern birds also have this trait, such as:

Hoatzin. To sum up, birds are birds.

So, life is designed and created, according to its kind, and the truly great one is the Creator!

Chickens evolved from birds, first birds evolved into pheasants, and finally humans domesticated into domestic fowl. Chickens are not descendants of dinosaurs because dinosaurs had collectively perished in ancient times. Chickens evolved through birds to become what they are now.

It's that it's slowly changing, and it's becoming very good, so that it slowly flies, and it's also a good change, which is affected by the environment. This is the offspring of a dinosaur, good.

Chickens evolved due to some mammals. It is a living creature that belongs to the land. Not descendants of dinosaurs. Such a statement is ridiculous.

Yes, scientists have found that chickens are the offspring of dinosaurs.

In fact, dinosaurs are the common ancestors of modern birds, and chickens also belong to birds, so it can be said that chickens are descendants of dinosaurs, and to be precise, chickens evolved from dinosaurs.

According to the research of biological researchers, chickens evolved from ancestral birds, and ancestral birds are not suitable for large dinosaurs because the entire earth's environment has changed after the earth was hit by meteorites.

As a result, some dinosaurs gradually became extinct, and some dinosaurs began to change their bodies. In addition to its own body becoming smaller, it also grew feathers and beaks to suit the living environment, and its mutated dinosaur is the ancestral bird.

Some scientists have compared the genes of birds and dinosaurs, and found that the DNA sequence similarity between birds and dinosaurs is as high as 80%, so that there must be a certain connection between birds and dinosaurs, and birds are likely to be creatures evolved from dinosaurs.

This discovery also shocked the scientific community, and many scientists later began to study the relationship between birds and dinosaurs, and compared the skeletons of Archaeopteryx with dinosaurs.

The final comparison results showed that Archaeopteryx and dinosaurs were very similar, so it is very likely that the ancestors of Archaeopteryx were dinosaurs. And the ancestor of the chicken is Archaeopteryx, so it is estimated that the ancestor of the chicken is a dinosaur.

The evolution of dinosaurs to birds: the body size became smaller (the bones were hollow; skull swelling; Forelimbs are getting longer and longer) - feathers grow on the surface of the body - to survive in trees to avoid injury or find food—and have the ability to glide and fly.

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.

Researchers have found that more than 90% of the mature feathers of modern birds are composed of -keratin, and the diameter of the structural fibers formed by it is only about 3 nanometers, which is the molecular structure that supports the flight of birds. Although the flight feathers of modern ornithosaur fossils also have a small amount of -keratin, they are mainly composed of -keratin.

But it was the discovery of the double giant raptor, and the text titled "Dinosaurs Flying to the Blue Sky", broke the stereotype of dinosaurs in people's minds and was quite attractive. The article begins with a vivid presentation of the bulky, sluggish dinosaur and the light, nimble bird, two seemingly unrelated animals in the reader's mind.

Tell us that during the Mesozoic Era, a branch of the dinosaur evolved into a soaring bird after a long period of tearing down the plum, and then described the general process of this scientific discovery. These results indicate 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.

This is a popular science article that introduces people to a hypothesis that scientists have put forward based on research: birds are likely to be descendants of a small dinosaur. At the end of the 20th century, Chinese scientists discovered for the first time in western Liaoning Province the dinosaur Luhengchi Stone with feather imprints, which provided evidence for people to imagine the evolution process of dinosaurs flying into the blue sky and changing into birds.

The article not only reveals the major discoveries made by scientists in paleontological research, but also opens the door to the science of paleontology to students, arousing their strong interest in science.

Chickens evolved from dinosaurs. In fact, the answer we said above is scientific and comes from the perspective of genetic mutation and biological evolution. Because we know that biological evolution is actually the result of genetic mutations, relevant data show that chickens evolved from dinosaurs.

If you don't believe me, you can take a look at the schematic diagram of the Tyrannosaurus Rex Evolution Chicken. Dinosaurs were oviparous animals.

The first chicken appeared because the dinosaur egg mutated, and the chicken's DNA mutated, so the first ancestor chicken hatched, so there were eggs before the chicken. This is the classic answer.

The Archaeopteryx is very different from the chickens we see now, and can only be called a chicken. Later, after a long period of noisy artificial selection and natural selection, the genes of chickens became stronger and stronger, and we had our current chickens.
