Did the chicken come first or the egg came first?! Tell me why!

A controversial but inconclusive question is now scientifically confirmed: "The chicken comes before the egg". Researchers at the University of Sheffield and the University of Warwick in the United Kingdom have teamed up to scientifically scrutinize the age-old chicken-and-egg debate.

In the end, the scientists concluded that there must be chickens before there are eggs, because the formation of eggs requires a special protein that is only present in the ovaries of hens. Colin Freeman of the University of Sheffield said: "We have always suspected that there were eggs before chickens, but now we have scientific evidence to conclude that in fact there are chickens and eggs.

Egg Formation "Egg formation requires a protein that has been known to the scientific community for a long time, but after careful study, we can clearly see how this protein controls the formation of eggs. The protein, known as OC-17, acts as a catalyst that accelerates the development and formation of eggshells. Using a supercomputer to amplify the structure of an egg, scientists found that OC-17 initiated the crystallization of the eggshell in its initial form.

This protein converts calcium carbonate into "calcite crystals", which are the building blocks of eggshells. John Harding, professor in the Department of Engineering Materials at the University of Sheffield, said: "Studying and understanding the process of laying eggs is an interesting subject in itself, but more importantly we can apply it to designing new materials. ”

The one that came first was the egg. Whether it came first with the egg or the chicken. Darla Zelenitsky, a paleontologist from the University of Calgary in Canada who specializes in dinosaur breeding, said

Until now, the question of whether the egg or the chicken came first has not been answered. But as the research deepened, the mystery gradually became clear: dinosaurs first built nests similar to birds' nests, laid eggs that resembled bird eggs, and then dinosaurs evolved into birds (chickens are also a type of birds), which is clear, eggs preceded chickens.

Chinese paleontologists from 100 million years ago"Caged spine"Fossilized embryos have been found to have regular cell migration and recombination during embryonic development, which means that at some point in history, a species that resembles a chicken, but is not a chicken, has produced its first "egg" because of a genetic mutation, and therefore for a single individual chicken, it is a chicken that has an egg and then a chicken.

Chicken or egg? Aristotle, a scholarly authority active in 3000 B.C., said: "There is an egg without a father and a mother, and the first chicken pops out of the egg".

Did the chicken come first or the egg came first? It's a difficult question for us. But on the issue of first-come-first-served or first-served, we can make a decision.

Chicken or egg?

The key to solving the problem is how we define the "egg" -- if we think that the "egg" must be the egg laid by the chicken, then it must be the chicken that came first.

From a scientific point of view, we start with the first life on Earth, and the first life on Earth should be infinitely close to the way bacteria or viruses reproduce.

Eggs, of course, are chickens first, and eggs later.

1. According to the analysis of the evolution of organisms, I think there are eggs first;

Just like the evolution of man, eggs are the tissue of thousands of cells, and then the egg evolves into a chicken.

It's like a butterfly that first turns from an egg into a caterpillar, then through a cocoon, and finally breaks out of the cocoon, that's the real butterfly ......

2, but according to recent reports, scientists from the University of Sheffield and the University of Warwick in the United Kingdom recently gave a definite answer to this question: "There are chickens first." A team of researchers found that eggshell formation relies on a protein called OC-17, which can only be produced in the ovaries of hens.

The researchers concluded that the first egg could only be produced if there were chickens first!

From a scientific point of view, we start with the first life on Earth, and the first life on Earth should be infinitely close to the way bacteria or viruses reproduce.

The key to solving the problem is how we define the "egg" -- if we think that the "egg" must be the egg laid by the chicken, then it must be the chicken that came first.

In the long history of the evolution of life on the earth, living things are constantly evolving, when the ancestors of the first chicken (when they were not chickens) laid eggs, the eggs hatched into our current chickens, so it was the first egg, and the egg came out of the ancestor of that chicken. So, first came the eggs, hehe.

Chickens lay eggs, eggs lay chickens! Species, species, in the derivation of all things, there is something first, and then there is a species. In the process of hybridization and reclassification, the species fission into new species and finally reproduce through stereotyped branches, and in the process of reproduction, it determines its own effective reproduction mode according to various special conditions of the environment, namely:

Oviparous, viviparous, nursing, oviparous lactation, anti-chicks....That's why I'm passionate about chickens and eggs.

Chinese paleontologists from 100 million years ago"Caged spine"Fossilized embryos have been found to have regular cell migration and recombination during embryonic development, which means that at some point in history, a species that resembles a chicken, but is not a chicken, has produced its first "egg" because of a genetic mutation, and therefore for a single individual chicken, it is a chicken that has an egg and then a chicken.

Neither. It's a question that depends on what answer you want to get.

I'll give you a scientifically backed answer

There are eggs first, because chickens hatch from eggs, but you will ask where the eggs come from.

Because as soon as an animal is born, its genes determine what it is.

No other major mutations will be created, so it will be the next generation that can mutate.

So there must be an animal that lays a mutated egg before there is a chicken.

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.

Eggs 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.

The animal that lays the "first egg" is not called a chicken...

Chickens were transformed from dinosaurs, so there were chickens first.

First, there was a chicken study that said that there is an element in the eggshell, which is only present in the ovaries of chickens, so there are chickens first, and then eggs can be conceived.

This question has been around for a long time, but there is no one absolutely right answer, and there can be no one.

This is not a matter of science, but of logic.

Let's assume that the chicken here refers specifically to the domestic chicken, and the egg refers specifically to the egg. Otherwise, if the dinosaur egg is also counted in the scope of "eggs", the answer must be that there are eggs first, and there will be no debate for so long.

The answer can be either the chicken or the egg. It depends on the identification of the first "chicken" and the first "egg".

According to the more popular view now, birds (including chickens, of course) evolved from a branch of the dinosaurs. And the evolution of species is an extremely long and gradual process. Even from the end of the Cretaceous period, when the dinosaurs became extinct, it is more than 65 million years ago, and the evolutionary process from dinosaurs to birds must have begun even earlier.

In such a long evolutionary process, it has gone through millions of generations and countless small evolutions to come to the "chicken" we see today and discuss here.

Suppose the first dinosaur that started this evolutionary process was N1, and it laid an egg N1, N1 hatched the second generation of N2 in the evolutionary process, and N2 gave birth to the egg N2, followed by N3, N3, N4, N4, N5, N5, 、......ni、ni、ni+1、ni+1……Until today's N1000000 and N1000000, in this process, the characteristics of dinosaurs continue to decrease and the characteristics of chickens continue to increase, so the generation of animals Ni is defined as the first "chicken", and which egg Ni is defined as the first "egg", which is the crux of the problem. Suppose N800000 is defined as the first "chicken" and its egg N800000 is defined as the first "egg", and the conclusion is that there is a chicken and then an egg, and if N799999 is defined as the first "egg" and its hatched N800000 is defined as the first "chicken", the conclusion becomes the first egg. The process is so long, the evolution is so slow, the changes in each generation are so small, there is absolutely no clear demarcation, before there was no doubt about the dinosaur, and one generation has changed into the undoubted chicken.

In this process, you can define N8000000 as the first chicken, N7000000 as the first chicken, and the same is true for the definition of eggs.

So don't seek a clear and absolutely correct answer to the question of chicken or egg: it can be the chicken or the egg, depending on your identification of the first "chicken" and the first "egg".

Chicken or egg?

Do you think it came first, the chicken or the egg?

Did the chicken come first or the egg came first? It's a difficult question for us. But on the issue of first-come-first-served or first-served, we can make a decision.

Chinese paleontologists from 100 million years ago"Caged spine"Fossilized embryos have been found to have regular cell migration and recombination during embryonic development, which means that at some point in history, a species that resembles a chicken, but is not a chicken, has produced its first "egg" because of a genetic mutation, and therefore for a single individual chicken, it is a chicken that has an egg and then a chicken.

Chicken or egg? Aristotle, a scholarly authority active in 3000 B.C., said: "There is an egg without a father and a mother, and the first chicken pops out of the egg".

Two understandings: 1. If the question is whether there was a chicken or an egg: from an evolutionary point of view, it should be the chicken that came first. Because only when a certain species evolves into an animal called a chicken, then the eggs laid by chickens can be called eggs.

2. If the question is the chicken or the egg: of course, the egg comes first. Because dinosaur eggs, crocodile eggs, and other eggs can appear much earlier than chickens.

This question again.

If the egg was laid by the chicken, it was the chicken that came first.

If the chicken hatches from this egg, it is the first egg.

Your question involves the study of "biological evolution", because there are still many natural mysteries that have not been solved, so there have always been different opinions on this issue

Some people say that first there are chickens, then there are eggs; Obviously, the eggs are laid by chickens, which is a very common natural phenomenon and there is no criticism;

There are also people who say that there are eggs first, and then there are chickens, so I don't think this statement is necessarily wrong, why? According to the theory of biological evolution, in the process of biological evolution, there will also be "mutation", for example, according to the traditional saying, fish can mutate, become reptiles, and then mutate into mammals, etc., then, it is likely that in ancient times, as the "ancestor of chickens" an ancient animal, laid an egg (of course, it is also a bird), this egg obtained special environmental conditions, and after a long period of gestation, hatched the world's first "chicken";
