Are chickens evolving or degenerating? What did chickens evolve from

Evolution and degradation are both, the degradation is that the chicken cannot fly, but it has adapted to the way of coexistence with people, that is, from the pheasant to the meaty broiler, the nourishing black chicken, and so on.

From the loss of flight function is a degradation, for it to become the chicken that people need is evolution.

Evolution in nature can also degenerate at the same time. The two coexist.

Being kept in a cage and unable to adapt to the survival of the outside world. The ability to survive in nature also decreases. Therefore, it cannot but be said that this is its degradation.

This is due to changes in the environment.

Adaptation Some of the original features are no longer needed.

And it disappears as the years go by, and that's a natural phenomenon.

It has nothing to do with evolutionary degradation.

The so-called evolutionary degradation is defined in order to adapt to nature.

What is the concept of evolution?

It's not a question of whether to fly or not.

It's a question of adaptation to the environment.

As you wish.

Monkeys can climb trees with great agility. What about people?

Degraded, he has lost the instinct to survive.

It doesn't matter if it's evolution or degradation, it's just adaptation.

Evolved. Now they have learned to spend a lot of money

There are gains and losses. The chickens are comfortable, they are all fat, and their wings can't hold up.

The original ancestors of our human beings also went up to the tree, but we can't, is it that we humans have faded?

According to evolutionary biology, chickens evolved from a species of bird. And first there were eggs, and then there were chickens.

The ancestors of domestic chickens were domesticated from the original chicken, and the history of domesticating chickens in China has a history of about 8,000 years. Primordial chickens first appeared 9 million years ago, when humans and chimpanzees shared the same ancestor. The proto-chicken evolved from an earlier species of bird, which in turn originated from the avian dinosaurs.

Evolutionary process:

Species evolution is a very slow process, and it is difficult to say on what specific day the birds of the order Chickiformes evolved into protochickens. Fundamentally, the evolution of species is due to changes in genes, because the traits that can be inherited are determined by genes. If there is a distinct characteristic in the genes, then the species will also be different.

However, genes do not change dramatically all at once, genes only change little by little with food, environment and other factors, and this change will be passed on from generation to generation. Over time, the quantity changes to the mass, and the genes of the offspring have changed significantly from the genes of the ancestors, so that a new species is born.

The genes of the ancestors of the original chicken changed over time, and eventually one day they gave birth to a special egg, and the gene contained in this egg is the gene that we can call "chicken", so the egg eventually hatches into a chicken, and then the chicken continues to make the genes continue by laying eggs and hatching chicks. Therefore, it is only possible to have chickens later if there are eggs first.

Chickens evolved from birds. Chickens are a type of poultry derived from wild raw chickens, which have been domesticated for at least about 4,000 years, but it was not until around 1800 that chicken and eggs became mass-produced commodities. The types of chickens are turkey, black chicken, pheasant, etc.

And the rooster is also one of the 12 zodiac signs.

Chinese chicken culture has a long history and rich and colorful connotations. In the first phase of the culture of Dadiwan in Tianshui, Gansu Province, it has been found that about 8,000 years ago there is the word "chicken" in the oracle bone inscription of our country, indicating that our country knew chickens more than 3,000 years ago, and raised chickens in China has a history of 8,000 years, and there is a history that can be checked by words for at least more than 3,000 years, which is one of the earliest countries in the world to raise chickens, and it is also the first country to find that chickens have a variety of medicinal values.

Yes, and most likely 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.

Tyrannosaurus rex was a massive carnivorous dinosaur. This fossilized femur was discovered in 2003 in Montana, USA. A team led by Mary Schweitzer, a researcher at North Carolina State University, took a closer look at the fossil and found fragments of protein collagen that remained in the fossil.

"For hundreds of years, it was believed that the process of fossilization destroyed all the original material, so that no one looked closely at the real old bones," Schweitzel said. However, the researchers found through mass spectrometry that the Tyrannosaurus fossil contained amino acid sequences, which are the building blocks of proteins.

This specimen looks like collagen in chickens and bears similarities to frog and newt proteins.

It's just that these dinosaurs gradually adapted to the environment and evolved into protochickens, about 4,000 years ago, people began to raise it, and gradually it will not fly, and will only glide for a short distance without changing direction.

Chickens evolved from eggs, in 100 million years ago it should be said that it was the dinosaur incident, the dinosaurs dropped the little dinosaur eggs and fled, and then there were chickens, probably this means, this is the conclusion of scientists, I remember that I had a collection of this note in 08 years, and I had time to find it out.

Belonging to birds, evolved from birds.

Chickens belong to the class Ornithischia, Pheasantidae, and belong to the same category as long-tailed pheasants, peacocks, etc.

Chickens are said to be the first to fly animals called "protochickens". This kind of raw chicken still exists, foraging on the ground and sleeping in trees. Domestic chickens gradually lose their ability to fly during long-term captivity. As for the various breeds of chickens now, they are artificially bred.

The history of chickens is redundant to look at the history of chickens from the beginning of life on Earth, but when considering the relationship between chickens and humans, it makes sense to start from 100 million years ago, when the last common ancestors of humans and chickens lived. At that time, everyone was a reptile, and 100 million years ago, the ancestors of mammals gradually separated from the ancestors of birds and modern reptiles. Then, about 100 million years ago, birds evolved from dinosaurs – and the theory that birds originated from dinosaurs has been widely accepted due to the many fossils unearthed in China in recent years.

The ancestors of the birds belonged to a branch of dinosaurs called the Void Bone Dragon, and the terrible Tyrannosaurus was also a member of this family, which is really a strange relative. The earliest bird was the Archaeopteryx of the Late Jurassic, which was the size of a crow and had sound plumage, but still retained some distinct reptilian features. X0d protopherds appeared about 800,900,000 years ago, and they evolved from chiniformes, and the current members of the order also include mound pheasants, grouse, and spitted pheasants.

There are several types of raw chickens, including red jungle chicken, gray jungle chicken, green jungle chicken, and Ceylon wild chicken, etc. In 1896, Darwin first proposed that modern domestic chickens were domesticated from the red junglefowl, because the red junglefowl could be crossed with domestic chickens to produce fertile offspring. This view was later confirmed by the Mitochondrial DNA Institute.

x0d archaeological evidence suggests that the Chinese began raising chickens at least around 5400 BC, a history that may even go back to 8000 BC. However, at that time, whether the chickens raised by Chinese were the same as modern domestic chickens, we are not sure. Some scientists believe that the modern domestic chicken originated from the Harappan culture (2500-2100 BC), a bronze civilization in the Indus Valley, and later spread to the Mediterranean.

The ancient Greeks said that chickens came from Persia, which is similar to "rice comes from shops", referring to goods** rather than the birthplace of chickens.

Chickens evolved from eLong.

Birds evolved from the degeneration of their wings from the sky to the land.
