The chicken or the egg came first in the world? You have to think about it

According to the American Life Science Network, Darla Zelensky, a paleontologist at the University of Calgary in Alberta, Canada, has a clear answer to the puzzle after studying the fossilized dinosaur eggs from 77 million years ago: dinosaurs first built nests that resemble birds' nests and laid eggs that resemble bird eggs, and then dinosaurs evolve into birds (chickens are also a type of birds), which is clear that eggs preceded chickens. Chickens evolved from these carnivorous dinosaurs that laid egg-like shapes.

This issue needs to be discussed separately.

1. "Egg" refers to "egg" in a broad sense, such as "snake egg", "dinosaur egg", "turtle king bastard", etc.

In this case, the world has eggs first, and chickens later. It is hereby proven as follows:

According to Darwin's theory of evolution, birds evolved from reptiles. That is to say, before there were birds, there were reptiles. As we all know, reptiles are "egg-born", such as dinosaurs. That is, before there were birds, there were already eggs.

Chickens belong to birds, so chickens appear after the eggs. That is, the eggs that came first in the world, and the chickens that came later.

2. "Egg" refers to "egg" in a narrow sense.

In this case, the world has chickens first, and eggs later. It is hereby proven as follows:

"Eggs", as the name suggests, are eggs laid by chickens.

As for how the world's first chicken appeared, here is another classification discussion:

1) A female bird that is not a chicken for some reason gradually becomes a chicken while it is alive. Let's name the bird A, then A is hatched from the "A egg", and the eggs laid after it becomes a chicken are called "eggs". Thus, the world came first with chickens, and then with eggs.

2) Some kind of bird egg that is not an egg, such as an "egg", for some reason, hatches a hen. Then the eggs laid by this chicken will be called "eggs" in the future. Thus, the world came first with chickens, and then with eggs.

In summary, as mentioned in (1) and (2) above, there are chickens and eggs in the world first.

3. Special circumstances. The chicken here refers to the "prostitute", and the same as 1, the chicken that comes first with the egg and then comes from the world. Certification.

First there is the egg, and then there is the excitement, because the egg may be born by another animal, but after the egg hatches, it is a chicken, and then it repeats, and repeats...

There are eggs first, and there is a program that specifically talks about this problem, mainly because of genetic variation. Genetic mutations occur every time a new life is born, and the "ancestor" of chickens (said to be a type of bird) from ancient times will have a genetic mutation every time they reproduce, and when the generation closest to chickens lays eggs, they have all the genes that belong to chickens, that is, eggs. So it's the eggs that come first, and then the chickens hatch.

Chicken or egg?

This seems to be everyone's confusion, but we should still make sure that it is the egg that came first. Today's domestic chickens are derived from wild wild chickens, which have been domesticated for at least 4,000 years. Early domestic chickens were drilled out of eggs laid by a single raw chicken.

Many experts believe that the protochicken is a type of pheasant that is the ancestor of the chicken we see today. But there are also those who believe that today's chickens are the product of crossbreeding of different species of chickens. From an evolutionary point of view, there is no question of whether the egg lays the chicken or the chicken lays the egg, because the early members of a species, whether chickens or other organisms, are the descendants of another similar species.

Egg. Chicken or egg is actually a matter of evolution or mutation, and it is a question of the emergence of a new species.

Whether it comes first with the chicken or the egg, let's analyze the "first chicken". According to Darwin's theory of evolution, we can understand that the predecessor of chickens is birds, which are birds, and birds are all "oviparous animals", that is, this "first chicken" must be ** an egg. Since what comes out of this egg is a "chicken", then this egg can certainly be called an "egg".

Of course, some people will say, how did this first "egg" come about? Isn't it a "chicken" birth?

So, let's analyze, the animal that lays the "first egg", must it be a chicken?

Not necessarily. The animal that laid the "first egg" is the ancestor of the chicken, and we might as well call her the "ancestor of the chicken". "Jizu"Like his companions, he laid a lot of eggs (not eggs, note), but at one point he laid an egg that was always special, because it was an egg that later hatched what we call the "first chicken".

Of course, this is the "first egg".

The "chicken ancestor" gave birth to the first "egg" with its inevitable and accidental factors. For example, sex lies in the fact that in the evolution of birds to chickens, there will always be a chance for a "bird" to lay its first egg, and chance is that the egg is produced from an individual of a certain "bird". There are many factors for this accident, such as light, sound, disease, and so on.

In other words, the animal that lays the "first egg" cannot be called a chicken.

Did the chicken come first, or did the egg come first? If there were chickens in the world, but chickens hatched from eggs, but if there were eggs that appeared first in the world, and the eggs were laid by chickens, this seems to be a very contradictory question. This question has plagued mankind for thousands of years, not only stumped the ancients, but also a large number of modern scientists.

Finally, after years of research, scientists have finally come up with the answer. Today, let's take a look together, maybe we were all wrong before.

After a series of studies, a British scientist found that the formation of eggs requires a special protein, which is produced in the body of hens, and without this special protein, eggs would not be formed. In other words, if there were no hens, they would not produce these substances, and there would be no eggs. Therefore, it is scientific to have the chicken before the egg.

Next, we can't help but ask: since there are chickens first and then eggs, then how did chickens come about?

The first fossil of the world's first chicken found is 66.7 million to 66.8 million years old, and this is by far the first modern bird fossil of the dinosaur age found by scientists in the Northern Hemisphere.

At the same time, researchers have found that dinosaur eggs are similar to eggs in many ways. Researchers have found that modern birds appeared just before the end-Cretaceous mass extinction event (less than 1 million years before the asteroid hit Earth, which wiped out all the big dinosaurs). So, they guessed that the ancestor of the chicken was a pterosaur of dinosaurs, and the chicken evolved from a dinosaur.

The world is so big that there are no surprises, chickens are actually from the essence of dinosaurs, we often say weak chickens, it seems that we are all wrong, the ancestors of chickens are dinosaurs, but not weak chickens, and the appearance of chickens is earlier than humans, chickens really can't be called "weak chickens".

With the speculation that chickens evolved from dinosaurs, we can better understand the answer given by scientists that "chickens come first, then eggs". We boldly guess that the first in the world was just the evolution of dinosaurs, and then chickens laid eggs, and then chickens laid eggs, and eggs laid chickens, and life continued in this cycle, and chickens continued to evolve, and finally became what we see now.

In fact, there is no need to bother experts about this question, we only need to change this question a little to get the answer, try to ask which animal cub was born in front of its mother? Therefore, sometimes you can't just look at the surface of a problem, you have to learn to think about it from a different angle, otherwise you will be surrounded by problems. When someone asks this kind of question in the future, you can directly say that it is the chicken that comes first and then the egg!

Guys, what do you think?

Chicken or Egg The question of "chicken or egg" 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

Chickens are one of the earliest domesticated "six animals" by humans, and in the history of mankind, chickens have been recorded for a long time. According to foreign research, it has been found that in fossils such as Tyrannosaurus rex and Tyrannosaurus rex, the protein structure contained is similar to that of chickens. At the same time, the common ancestor of birds is Archaeopteryx, which also evolved from dinosaurs.

In the process of environmental evolution, with the advent of the Ice Age, dinosaurs became smaller in size and began to grow hair on their epidermis, and after a long period of evolution, they gradually evolved into various birds and animals. According to this line of thinking, the ancestors of chickens were dinosaurs, and dinosaurs were oviparous. It can be said that before the appearance of chickens, the ancestors of chickens began to lay eggs.

So, it should be the eggs first and then the chickens. Moreover, eggs will hatch chicks in a specific environment, and a long time ago, there was no science and technology like now, and without the hatching of chicken mothers, eggs would not produce chicks on their own. Since it is an existing chicken, then there are no eggs, and the chicken comes from **?

Many experts agree that chickens are mutated from other organisms. If we think about it seriously, a long, long time ago, there were not so many species on the earth, and because of changes in the environment or climate, biological genes were also affected, so there were many organisms on the earth.

First of all, this is an academic question, whether you have a chicken or an egg first, which is a difficult research question, so there is no answer so far.

Scientists in the United Kingdom have discovered a substance that catalyzes the formation of eggshells, which is only found in the ovaries of chickens.

Only in the right. In other words, if there are no chickens, there is no such protein, then it is impossible to form eggshells at all, and the formation of eggshells can also protect the chicks from being successfully hatched, so they conclude that there are chickens first, and then eggs.

Most people may think that it should be the first egg, but according to the latest scientific evidence, it is actually the chicken that should be there first. The above protein has been confirmed to be inseparable from the formation of eggs, and scientists have also learned about the formation process of eggs.

In fact, it is not difficult for us to answer the answer to this question, and we can use reverse extrapolation to answer this question. If we talk about the first egg, then it proves that the egg originally existed in this world, but how could there be an egg in the world for no reason? This undoubtedly does not make sense.

Furthermore, with an egg, it was not hatched, how did the first chicken come out?

So let's assume that if there were chickens first, all of this would be easier to explain. We all know that all creatures in the world have evolved gradually, so the theory that chickens evolved from other animals is obviously true, so before, the ancestors of chickens did not necessarily lay eggs, with the change of genes and the influence of the environment, chickens gradually formed, and then began to lay eggs to reproduce. This explanation is perfect.
