Excuse me, is it the chicken or the egg, is it the chicken or the egg?

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.

Upstairs is right.,I also watched it.,The chicken that came first.。。

Hello! The most concise way is that there is a chicken first, and then there is an egg. Scientists have confirmed that some people copied it over.

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".

Do you think it came first, the chicken or the 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.

Eggs are, of course, chickens first.

Existing eggs.

It is a mutant egg laid by an avian animal, or a cross between two animals. Now it is common to see mules. If mules can be inherited, they will be the same as chickens.

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.

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

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

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.

As an academic issue, there are eggs first: the ancestors of chickens are called chicken-likes, and the eggs laid by a certain chicken-like chickens are mutated and become chickens as a species.

Didn't explain!! The chicken is a mutation of the egg of a certain type of chicken species, and the chicken lays eggs again!! How do you explain that? Is the mutated egg an egg?,If you count, it's not a chicken-like species.,If not, where does the chicken come from??

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

So what comes first, matter or energy?

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.

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".

Then there are chickens directly, so do you want eggs?

There should be eggs first, and everything in the world evolves slowly.

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?

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