Life on earth has evolved from amino acids-unicellular organisms-multicellular organisms-to arthropods-ringed animals ... fish-reptiles-birds.

Complete eggs (with shells) probably began to appear from reptiles, mainly to adapt to the dryness of the land environment and maintain the moisture in the eggs.

Chicken is a kind of birds, which appeared much later than reptiles. So there was an egg first, and the first chicken came out of the egg.

The appearance of the ball can be said to be an adaptation of ancient marine life shortly after it left the ocean and landed.

If you think further, the earliest structure of an egg is an egg cell, which is a form of sexual reproduction. So push forward, when the life form becomes more and more primitive, sexual reproduction will be replaced by asexual reproduction, and the balls will not exist. In this sense, "egg" can be said to be later.

That is, there is a life form like "chicken" first, and then there is a reproductive form like "egg"-here "chicken" and "egg" are not literal.

Chicken or egg first? This is an old and difficult problem to solve.

Legend has it that Zhuge Liang has three spirits. Zhou Yu asked Zhuge Liang a difficult question: which came first, the chicken or the egg? Zhuge Liang replied: there was a chicken first. Zhou Yu said with a smile, no chicken, no eggs. Zhuge Liang asked: If the first egg is an egg, what about the chicken? Zhou Yuyi was speechless, his anger was born from the outside, his blood was wet from the inside, and he began to vomit blood.

This folk story is far-fetched, full of loopholes, and has no substantive help to the answer to the "egg mystery". Zhou Yu's questioning is puzzling. Zhuge Liang's rhetorical question is full of sophistry. However, from this folktale, we can feel how radiant, deeply rooted in people's hearts and how "Theory of Three Represents" the "egg dispute" is.

Chicken or egg first? The "first chicken pie" thinks that eggs are born by chickens, so there are chickens first. The "egg first pie" thinks that chickens are hatched from eggs, so there are eggs first. This is a big trouble in logic. Although eggs are laid by chickens, aren't chickens hatched from eggs? It can be said that chicken is right for eggs! Both sides are caught in a cycle. It's like running in a circle, you can't tell who is in front and who is behind.

Chicken or egg first? Many masters and sages can't answer this eternal question, but I can! Because I am much better than them. . .

I am an out-and-out skeptic. The first thing that comes to mind in this "egg fight" is a joke. The joke goes like this: The driver took part in the "CET-6 interview", and the examiner asked the driver: If there was a man and a cat in front (that is, the kind of animal that caused an uproar in major forums recently), would you hit people or cats? The driver replied without thinking: of course it is a cat! The examiner said: Wrong! You should brake immediately!

Brake immediately! This is the correct answer to the question! The examiner gave the driver a thinking trap! The problem is that you have to jump out of the trap. Only in this way can we have a wide choice. Exactly: the future is boundless, thousands of villages and thousands of townships!

The problem of the "egg dispute" is also here. It is difficult to verify the earliest time when this question was put forward, but it is certain that the background of this question was put forward in the era of science and its underdevelopment. So the first and most important thing to do is not how to answer this question, but to question the scientific nature of this question.

The theory of evolution tells us that any living thing is constantly evolving. So what is a chicken and what is an egg? How to define chicken and egg in time? Chicken or egg first? So what year does this chicken refer to and what year does the egg refer to? Obviously, the object of discussion is ambiguous! From a mathematical point of view, it can only be discussed in this way: which came first, the chicken or the egg? In 2004, which came first, chicken or egg? In 2003, which came first, chicken or egg? . . . And so on until the first year! And the answer is not necessarily the same every year. This means "which came first, the chicken or the egg?" Will present different answers at different discussion times!

Of course, "which came first, the chicken or the egg" is mainly asked in the first year, but the first such question has no basic biological knowledge. Secondly, the person who first raised this question had no basic biological knowledge in his mind. The so-called chicken and egg in this question is a static value, not a dynamic concept! The chickens and eggs here are obviously the chickens and eggs when the question was first raised. Not biological chickens and eggs.

The second problem of this "egg dispute" is that chicken is an egg-laying animal, so chicken and egg are the same creature, not two different creatures! Under such a premise, it is meaningless to discuss whether the chicken or the egg comes first. This is like saying whether a person has a left hand or a right hand first.

And the "egg fight" is really possessed by the above two places. "Chicken or egg first?" Evolved into "chicken or egg first?" . As mentioned above, organisms evolve, and the objects of discussion are both ambiguous. What are chickens and eggs? Can you give a specific time?

Get to the bottom of it: I want the first one, the first one, and I don't need specific time. It's just that if it's the first, it's not a chicken laying eggs!

Take a step back and say, which came first, the chicken or the egg? There are unscientific elements in this entanglement. People who have this idea regard the appearance of creatures as individuals! This is absolutely anti-science! Modern science tells us that creatures appear in groups! In other words, there is no first chicken and egg in the world! Only the first group of chickens and the first group of eggs. The so-called chicken and egg come first, without the entanglement of modern scientific knowledge, possession comes out of nothing!

If creatures appear as individuals. With the first chicken, how can chickens reproduce? The first egg comes first, so how can the egg reproduce?

Having said that, to sum up: which came first, the chicken or the egg, is an unscientific proposition. Let's take a step back to 654.38+00,000 to discuss that chickens and eggs are the same creature, and creatures appear as a population. For one chicken in this population, the chicken comes before the egg, and for another chicken, the egg comes before the chicken. For the whole population, it follows the probability distribution, that is, half of the chickens in the whole population have the egg first and the other half have the egg first! In other words, for chickens, chickens and eggs are produced at the same time!

Doubt everything, but don't doubt your ability to doubt!

There is an argument between chicken and egg. Chicken comes first.

From the perspective of biological evolution, of course, there are chickens before eggs. As we all know, organisms have evolved from low to high, from aquatic to terrestrial, and from simple to complex. Chickens belong to birds and evolved from reptiles, which evolved from fish, while fish originated from invertebrates. We know that lower organisms divide and reproduce on their own, while fish reptiles lay eggs, and when they evolve to a proper level, they produce the first egg. How to distinguish eggs from eggs? Quite simply, eggs are hard shells and eggs are soft shells. Therefore, we can understand that when an organism no longer differentiates to produce an egg, then this organism is the ancestor of this egg. Similarly, the first generation of chickens came from eggs and became the ancestors of eggs after laying eggs. So, the chicken comes first, and then the egg comes.

Chicken comes first, egg comes first.

The above is very clear, but it is also extremely absurd. How to master the hardness of eggs? This change is not immediate, but gradual. My thickness of 0.0 1mm can be regarded as an egg, so why not 0.009mm? I think eggs come first. First of all, a species can only be called a chicken if it has evolved to have the characteristics of a complete chicken, then that egg is the ancestor of the chicken, and the guy who laid this egg is not a chicken because he is a little shorter than the chicken, so it can be concluded that the chicken came first.

Eggs come first, chickens come first.

It is true that things change from quantitative change to qualitative change, but science is science, and science also has its definition, such as pH, with 7 as the standard, small is acid, and excessive is alkali. This is well known. So an egg is an egg and an egg is an egg. As for what the other party said about the ancestors of chickens, it was ridiculous and generous. The question we are discussing is which comes first, the chicken or the egg. Of course, eggs are eggs. You're talking about that guy's egg, not that egg, which just confirms what I said: the chicken comes before the egg. This is a matter of common sense. Eggs are naturally born by chickens, and chickens themselves are gradually evolved from birds.

Again, chicken comes first, then eggs.

If the other person wants to say that, I can't help it, so I can say that I am not a person and I am changing every day. Does that mean that one day we will become inhuman? Because science has proved that many human organs are degenerating, such as our wisdom teeth, and now many human beings no longer grow wisdom teeth, then the original definition is that human beings have 32 teeth (of course, accidental injuries such as knocking out are not recorded). Does it mean that those 28 teeth are not human now? This is very funny and absurd. What is a chicken? What is an egg? This is the most basic knowledge. The chicken I mentioned earlier is a chicken with complete chicken characteristics, not a data. The other person wants to say that eggs are not eggs, which is very funny. The eggs that can hatch chickens are not chicken eggs or anything, but that guy's eggs. Interesting. Do you know how many eggs that guy laid? Does that mean the rest is the same? Can hatch chickens? No, only this one is, so this one is naturally a chicken's egg, and of course it is also that guy's egg, which is not contradictory. The so-called Longsheng Jiuzi is different. This is an egg. So, there are eggs first.

Two bargains have eggs first, three stands have chickens first.

It's good that the other party put forward such a concept. The dragon gave birth to nine sons, and the nine sons were different. But I suddenly found that the other party may have overlooked an extremely important issue, and the other party may have actually fallen into a thinking trap. I have to ask? Must the ancestors of chickens be laid by eggs? Isn't it something else? Although according to the law of biological evolution, we generally believe that as one of the representatives of birds, when a chicken becomes a chicken, its path is likely to be egg-laid, but we can never exclude others! But we can be sure that chickens can lay eggs. If the chicken was born by his path, there is no doubt that the chicken came first, but at the same time, I can boldly say that if the path is as we have been expecting, the chicken will come first and the egg will come again. What I want to ask is, did the dragon lay nine dragon eggs or other eggs? The same guy laid several eggs, such as quail, sparrow, peacock and chicken. It's hard to say who would naively say that he laid a quail egg, a peacock egg, a sparrow egg and an egg? At the same time, the other party is obviously confusing. According to the law of biological evolution, that guy should have been very close to a chicken. Even if his eggs can't hatch a chicken for a while, then a chicken must be born later. So I stick to my point of view, that guy laid an egg and hatched a chicken, which is the ancestor of the chicken. And that egg is not an egg, because hatching is not only the reason of the egg itself, but also a series of factors such as climate and environment. Only eggs laid after hatching can become eggs.

Chicken comes first, egg comes first.

What the other party said was very good, but in fact it was your Excellency who confused the audience, not me. First, in order to suppress me, the other party deliberately raised a question of suddenness. I can say that biological variation is not what you say, but a problem of quantitative change to mutation. Chickens evolved step by step, and there is no doubt that they came from eggs. I have repeated the reason many times, so I don't need to repeat it. China traditional dragon gave birth to nine sons, although different, but all belong to the dragon species. Anyway, the eggs laid by the same guy are different, and the things hatched will be a fraction. Do we have to divide eggs into male eggs, female eggs, black eggs and white eggs? This is unnecessary, purely redundant. Anyway, that guy laid an egg and hatched a chicken. Is it necessary for us to argue whether this egg is an egg or not? The so-called environmental factors over there are secondary. Can it be said that swans hatch at the water's edge? At most, it affects some trivial details, such as coat color and texture, so the fact that it is an egg cannot be denied. And the guy who laid the egg really can't be called a chicken, so do we still need to deny such an egg? Of course, the egg comes first, then the chicken! !

Final theory

In fact, this is a common sense mistake in our consciousness. For example, we named the egg laid by chicken A as egg A, which gave birth to chicken B, and chicken B gave birth to egg B. In fact, chicken A is different from chicken B, and so are eggs A and B. They are constantly changing, or evolution, but we habitually divide them into chickens and eggs and forget their differences.

Actually, I don't know.
