The age old question is how many come first or come first

"Egg" does not simply refer to eggs, but egg-laying animals existed long before chickens appeared. So, there are eggs first, and then there are chickens.

Eggs, eggs, chickens in front, eggs in the back, of course, chickens first and eggs later.

I don't have a long scientific theory about the eggs that come first, but I do know that the change of biological breeds starts with eggs, for example, two different chickens cross to produce a new breed of chickens, which starts from the eggs born from the crossing, so there should be eggs first, and then chickens

It's been a long time, my eyes hurt and I haven't finished reading it yet.

It depends on how you define that "egg", if it's an "egg", there is the chicken first. If it is "eggs that can hatch chickens", there are eggs first. The "protochicken" before the appearance of the chicken accidentally laid a mutated egg that gave birth to the first chicken, and then hatched the first chicken.

First there is the egg John, an expert in evolutionary genetics at the University of Nottingham in the United Kingdom. According to the principle of genetics, the genetic material in an organism does not change throughout its life cycle, and because of this, the first creature to evolve into a chicken very long ago must have existed in an object in the form of an embryo, and the object that stored this embryo was the egg.

The organism inside the egg has the same DNA as the chick that hatches from the egg, and the first living thing to appear in the chicken species is the first egg.

For the conclusion of "the egg came first", many people unconsciously have a question, that is, how did the first egg come about? What is the creature that laid the first egg, if not a chicken?

Obviously, these doubts are layman's. This world is the world that evolved from the world of inorganic matter to the world of organic matter, and with organic matter slowly produced life, and the first egg was formed by the slow accumulation and evolution of organic matter.

Therefore, there are the eggs first.

It should be said that first of all, you should figure out whether you are asking about "eggs" or "eggs", "eggs" must be earlier than "chickens", because dinosaurs, for example, are also egg hatching, but "chickens" must be earlier than "eggs", because eggs born by other things are not called "eggs", since they are called "eggs", they must be born by "chickens", and there must be "chickens" first, and "eggs" must be regenerated first.

There were chickens first, and it has been confirmed.

This is a question that has been debated for a long time, and it has plagued people for thousands of years, and every time I think about it, I often get stuck in a causal cycle. Even some scientists have been puzzled and have not yet received an accurate answerIn fact, it is a question that people often ask, did the chicken come first or the egg came first? From some scientific point of view, there must be a chicken before an egg.

We all know that it belongs to the subclass of birds, is a kind of birds, at the beginning of scientists in the ovaries of chickens, found a substance that can form eggshells, the original proto-machine can lay eggs, but this egg can not hatch chicks, and to a certain extent, when this egg hatches chicks that can continue to lay eggs, inherits this gene, so all subsequent machines can lay eggs, and can also hatch chicks. The chicken or the egg is the most basic question in life, no matter from which point of view, it is the chicken and then the egg.

In ancient Greece, the famous philosopher Aristotle was very troubled by the problem of chickens and eggs, but he believed that both substances existed at the same time, whether there was a chicken or an egg. It's like a person is born without a father or mother, which is impossible, it does not conform to the laws and development of nature, so there is no possibility that there is an egg that will hatch directly into a chicken, because the egg is laid by the chicken. In the past, some special species in history, because of the development of the times, slowly evolved into chickens, and then slowly laid eggs and hatched chicks little by little, so it is said that there are chickens first and then eggs.

This question has been debated for a long time, whether from the point of view of animal and plant development, or from some scientific point of view, it is the chicken and then the egg. It is impossible for chickens and eggs to appear at the same time, no matter from any point of view, they are hatched chicks, and then chicks lay eggs, and then the eggs hatch chicks, so chickens are always in the first place.

Did the chicken come first, or did the egg come first?

First there were chickens. In the earliest days, it was not necessarily through eggs that the offspring were reproduced. It must have taken many years to evolve to the current method of propagating offspring with eggs.

I think there are eggs, from the perspective of biological evolution, the species of chickens is mutated in the environment of natural selection and survival of the fittest, and the genes are mutated in the genetic process, so there are eggs first, and what hatches is chickens, that is to say, the species that gave birth to chickens may not be chickens, and the above are all personal guesses.

First there were chickens. Because chickens evolved from other species, and eggs can only be laid by chickens, there are chickens first and then eggs.

Did the chicken come first or the egg came first? This classic question has plagued mankind for hundreds of years. Recently, British scientists claimed to have solved the mystery, and the answer is that there are chickens and then eggs, on the grounds that they have found a protein that can catalyze the formation of eggshells only found in the ovaries of chickens.

According to the British "Daily Mail" 14**, researchers from the University of Sheffield and the University of Warwick recently wrote an article entitled "Structural Control of Eggshell Protein Crystal Nucleus", which elaborated on the conclusion that scientists used a supercomputer to "amplify" the egg formation process: a protein called Ovocledidin-17 (referred to as OC-17) is a catalyst that accelerates the growth of eggshells, without OC-17 proteins, the appearance of eggs cannot crystallize to form eggshells. This protein converts calcium carbonate into the calcite crystals that make up the eggshell.

Calcite crystals are found inside many bones and eggshells, but hens form calcite crystals faster than any species——— producing 6 grams of eggshells every 24 hours.

Colin Freeman, Ph.D. from the Department of Engineering Materials at the University of Sheffield, said: "Scientists have previously discovered the OC-17 protein and speculated that it is involved in egg formation. But after careful research, we finally understood how it controls the egg formation process.

Interestingly, various birds appear to have proteins like OC-17 that catalyze eggshell formation. Freeman concluded, "There is a place to live with the eggshell, yolk and liquid that protects the chicks, and there would be no eggs without the OC-17 protein in the ovaries."

Therefore, there must be chickens and then eggs. ”

According to scientists, in addition to figuring out how chickens produce eggs, the research could also help develop new materials or ways to process them.

I searched for the information, take a closer look, it won't take a few minutes.

British scientists claim to have solved the mystery of the ages: first there is a chicken and then there is an egg.

Beijing time on July 14, according to foreign ** reports, the chicken or the egg first? This is a classic and often asked question, and the ultimate philosophical and scientific mystery that has lasted for hundreds of years. Now, with the help of advanced computing technology, British scientists have finally unraveled the mystery – and the answer is that there is a chicken before an egg.

Researchers have found that the structure of eggs depends on a protein found in the hen's ovaries, so eggs are only present when the hen is in the body. This protein, called ovocledidin-17 (OC-17 for short), is a catalyst that accelerates the development of eggshells, which are essential for protecting the yolk and egg whites, allowing the embryo to fully develop inside.

Scientists at the University of Sheffield and the University of Warwick used a supercomputer to "amplify" the egg-forming process. The supercomputer, called "Hector", was located in Edinburgh. The results showed that without OC-17 protein, the outer part of the egg could not crystallize, forming an eggshell.

This protein converts calcium carbonate into the calcite crystals that make up the eggshell. Calcite crystals are found inside many bones and eggshells, but hens form calcite crystals faster than any species – producing 6 grams of eggshells every 24 hours.

Dr Colin Freeman, from the Department of Engineering Materials at the University of Sheffield, said: "There has long been a suspicion that there was an egg, but the scientific evidence we now have proves that it was actually the chicken. Scientists have previously discovered the OC-17 protein, which is involved in egg formation, but after careful study, we can understand that the OC-17 protein actually controls the egg formation process.

This is a very interesting finding, and all kinds of birds seem to have proteins that can do the same job. ”

John Harding, a professor in the Department of Engineering Materials at the University of Sheffield, said the discovery had other uses. "Unraveling the mystery of hen egg formation is interesting in itself, while also providing clues to design new materials and techniques," he said.

Scientists have found innovative solutions to the problems of materials science and technology from nature – and we can learn a lot from them. ”

The egg or the chicken came first in the world? In order to find the truth, the chicken clan actually traveled to 100 worlds, where there were eggs or chickens first? In order to find the truth, the chicken clan actually crossed over to 100

Recently, Dara Zelensky, a paleontologist at the University of Calgary in Alberta, Canada, said that after studying the fossilized dinosaur eggs from 77 million years ago, a clear answer to the puzzle emerged: dinosaurs first built nests similar to birds' nests and laid eggs similar to bird eggs, and then dinosaurs evolved into birds (chickens are also a type of birds), which is very clear, eggs preceded chickens. Chickens evolved from these carnivorous dinosaurs that laid egg-like shapes.

The person who asks this question is brain-dead.

First came the eggs. Because chickens belong to birds, and from the perspective of biological evolution, birds evolved from reptiles, and reptiles reproduce by laying eggs, so there are eggs before chickens.

A British scientific journal has published a question that proves from an evolutionary point of view that there are eggs before chickens.

There was the egg, and the egg was a single-celled individual. It can be assumed that in ancient times, a bird should have given birth to a mutated egg in response to changes in the external environment, and this egg hatched and gave birth to what we now call chickens. So I think there are eggs first.

Instead of having a chicken or an egg (eggs and eggs are two different concepts).

The chicken or the egg.

The chicken-and-egg question is a question that has been debated for a long time and there has been no clear answer. In fact, the appearance of eggs was much earlier than the appearance of chickens, because as early as 280 million years ago in the Permian, reptiles appeared, and reptiles (such as crocodiles, dinosaurs, etc.) would lay eggs, and birds appeared in the Jurassic period 180 million years ago, and chickens appeared even later, but the question about "chicken or egg" is actually asked who comes first and who comes first, chicken or egg.

Chickens lay eggs, eggs hatch chickens, if you say that chickens appear first, then "how can no laying hens hatch"? If you say that the eggs appear first, you will encounter the problem of "who lays the eggs without the chicken", which is really confusing.

According to evolutionary point of view, there is no question of who comes first and who comes after chickens and eggs. As a species in the class of birds, chickens are differentiated from primitive birds, and eggs are the fertilized eggs of chickens (referring to eggs that can breed chicks), and in the long process of the formation of chickens, they have always been a bridge connecting the generations in the evolution of "primitive birds-chickens". In the formation process of chickens, there are three factors:

i.e. variation, heredity, natural selection. "Chickens" lay eggs (they can't be called chickens when they were more primitive), and eggs give birth to "chickens", which are not exactly the same between the two generations, and there are always differences in the offspring born to the same parent. A "chicken" can lay many eggs, but not all of them end up as adult chickens.

In the struggle for survival, individuals with favorable mutations get the best chance to preserve themselves, and the advantages and disadvantages are determined by nature, and chickens are formed precisely because nature gradually retains their good running. Variation characteristics such as more ground activities and poor flight ability, and differentiated from primitive birds. Obviously, heredity plays a role in maintaining and consolidating variation, which accumulates through heredity.

After a long-term, generational process of "chicken" to egg and egg to "chicken", under the action of natural selection, the variation of species is accumulated in a directional manner, resulting in the differentiation of species and the formation of new species, and the "chicken" slowly evolves and the egg also evolves.

Eggs are said first about chickens and then about eggs, so there are chickens first and then eggs.

The first chicken, because the chicken was degraded from the primitive birds of prey, the eggs that came after the chicken.

Of course, there were chickens first, and all life on Earth was born in the ocean and then slowly evolved.

You go and ask Nuwa Niangniang, he made the eggs first, but he still made the chickens first. Go to the temple and burn a stick of incense, and she will give you a dream.
