What came first - the chicken or the egg? ?

Question: “Which came first - the chicken or the future chicken, that is, the egg?” - has haunted man since ancient times. After all, one could not be born without the other. However, modern paleontologists have strong evidence and know the answer.

The history of the search for an answer goes back to ancient times. Aristotle also tried to get a reliable answer, and he lived more than 2 thousand years ago. As a result of thinking that eggs could not be the first, because they had to be laid by a bird, the Greek philosopher came to the conclusion that chickens and their product came into being at the same time.

In the Middle Ages, scholasticism emerged. This movement combined religion and science. According to biblical scripture, God created all earthly creatures and blessed them for reproduction. During the debate, the scholastics came to more complex conclusions, but they still determined the primacy of chickens. Darwin believed that the world arose from cells that were “self-animate,” and the rounded object of debate represented the largest egg cell. That's why it should be in the beginning.

Modern philosophers distinguish 2 approaches to the question:

According to some of them, there are no clear boundaries in the concepts of “chicken” and “egg”. The latter may exist in different types, for example, egg, egg, etc. There were also a great variety of intermediate forms of birds in the process of evolution. Before the hen's hour of existence, someone also laid eggs.
The second approach clearly distinguishes chickens and their eggs in the shell. With this formulation of the problem, the chicken should appear first.

Attention! British scientists have isolated a special protein from the shells of chicken eggs that is not found in other birds.

Paleontologists answer

Paleontologists unequivocally say that the oval future appeared first. The Galliformes order is considered the most ancient and numerous. The first representatives existed at the beginning of the Cenozoic.

Birds evolved quickly, resulting in the modern chicken. However, eggs in a dense shell appeared long before this. The relationship of modern birds with ancient dinosaurs has been scientifically proven. Confirmation is the discovery in Madagascar of the remains of a small creature similar to a dinosaur. At one time it had feather cover and actively flew.

Attention! With the help of eggs, the predecessors of dinosaurs reproduced - the first land reptiles, cotylosaurs, which existed more than 300 million years ago.

Despite the evidence, discussions about what came first do not subside and will probably continue for another dozen years.

Which comes first, the egg or the chicken: video

There is still a debate about what came first, the egg or the chicken. Scientists, philosophers and ordinary people have pondered this question for a long time. This is a mystery: a vicious circle, because if the egg came first from which it later hatched chicken, it should have been chicken, which demolished primordial egg– well, I think it’s clear; We won’t walk in circles forever, but let’s move on.

But it turned out that dinosaurs laid eggs similar to birds long before chickens appeared on Earth. A rare fossilized dinosaur nest helps answer the mystery of which came first, the chicken or the egg, two paleontologists say.

A small carnivorous dinosaur sat above its nest of eggs 77 million years ago on a sandy river beach. When the water level rose, the dinosaur ran away and its babies did not hatch.
Researchers are now studying the fossil nest and at least five individual eggs. The nest is a pile of sand about 1.6 feet (half a meter) wide, and weighs as much as a small person, about 110 pounds (50 kg).

“Some characteristics of the nest are the same as those of birds, and analysis can reveal how ancient in time such evolved characteristics as egg incubation, nest building, and pointy-tipped eggs are partial answers to the old question of which came first, the chicken or egg," said researcher Francois Therrien, director of dinosaur paleoecology at the Royal Tyrrell Museum in Alberta, Canada.

Answer?
It's still unclear whether the hen's or hen's eggs came first (the question asked in the original riddle), noted Darla Zelenitsky, a paleontologist at the University of Calgary in Alberta who was the first scientist to thoroughly study the dinosaur's nest.
But when interpreted literally, the answer to the riddle is obvious. Dinosaurs built bird-like nests and laid bird-like eggs long before birds (including chickens) evolved from dinosaurs.

« The egg came before the chicken« , Zelenitsky said. “Chickens evolved much later than the carnivorous dinosaurs that laid these eggs.”

Now the original riddle can be rephrased: Which came first, the dinosaur or the egg? Meanwhile, the new nest provides some of the strongest evidence in North America for a bird-like egg appearing before the chicken.

The fossilized nest was found in the 1990s and was stored at Canada Fossils Limited in Calgary, Alberta. There, Zelenitsky first discovered remains that were initially labeled as belonging to a herbivorous duck-billed dinosaur. (In 2007, the fossil remains were acquired by the Royal Tyrrell Museum of Palaeontology in Alberta.)

Zelenitsky realized that the nest and eggs actually belonged to a small theropod, a carnivorous dinosaur. In particular, the dinosaur that laid the eggs was most likely a maniraptoran, a group of theropods from which paleontologists believe birds evolved 150 million years ago during the Jurassic period.

“Nests of small theropods are rare in North America, and only Troodon dinosaur nests have been discovered in the past,” Zelenitsky said. "Based on the characteristics of the eggs and the nest, we know that the nest belonged to a caenagnathid [maniraptoran family] or a small raptor, both of which are small carnivorous dinosaurs closely related to birds."

One way or another, this is the first nest of these small dinosaurs found.

The only other maniraptoran egg nest found in North America was that of Troodon formosus.

Oviposition pattern
Nest analysis, detailed in latest issue journal Paleontology, gives paleontologists information about egg laying by this particular dinosaur and others, along with the evolution of different egg-laying patterns, Therrien said.

“Our study reveals a lot of information about the dinosaur that laid its eggs and how it built its nest,” he said.

For example, the position and spacing of the eggs suggests that the nest originally contained at least 12 eggs arranged in a ring around the flat top of a pile on which the theropod would have sat while incubating its eggs. The eggs were approximately 5 inches (12 cm) tall and, like bird eggs, were pointed at one end.

The study also shows that the dinosaur laid two eggs at a time on the sloping sides of the pile. This is not like crocodiles laying all their eggs at once, and more like birds laying one egg at a time. (The ancestors of crocodiles gave rise to dinosaurs and later birds.)

A special discussion was also created about this pressing issue, in which the following took part: geneticist John Brookfield - a specialist from the University of Nottingham, an expert in the field of philosophy David Papineau - University College London, as well as Charles Bournes - the owner of a poultry farm.

All three agreed that initially the egg appeared .

“During the life of an animal, the genetic material remains unchanged. Therefore, the first bird, which gradually developed into what is the modern chicken (apparently this was back in prehistoric times), first existed as an embryo inside an egg."

John Brookfield

The embryo in the egg has the same DNA as the chicken that hatches from that egg. From everything that has been said above from the point of view of evolution an egg should appear first.

Two other experts fully agreed with the geneticist’s conclusions, and the philosopher’s answer was simple and laconic:

“The first chicken came from an egg, therefore the egg came before the chicken»

David Papineau

However, do you think everything is so simple? But no...

A scientific team from the universities of Sheffield and Warwick (UK) has given an answer to the question that for centuries has puzzled the most brilliant minds of mankind: which came first - the chicken or the egg.

The chicken appeared first, scientists say.

The relevant research was carried out using a powerful computer, which simulated the process of the appearance of a chicken egg at the genetic level. At the same time, scientists discovered that the protein ovocledinin-17 or OC-17 plays a key role in its formation. He is involved in the creation of eggshells.

Without this protein, which is in the chicken’s body, an egg cannot appear.

“This protein has been known for a long time, but only now have we established that it is directly related to the formation of the egg and controls this process,” said one of the leaders of the work, Professor Colin Freeman. “It should be noted that various types birds exist various options of this protein, although they perform similar functions. Thus, chickens have a unique form of OS-17, without which the well-known chicken egg cannot be born,” he noted. As a result, British scientists were able to answer a scientific question that was considered unsolvable, establishing that the chicken appeared first, and only then the egg.

This conclusion is consistent with the results of modern genetic studies showing that the domestic chicken is the result of hybridization between the bank rooster and the gray jungle fowl, and, therefore, the clear line is the moment of obtaining the first hybrid female.

We must understand that these options for resolving the paradox do not negate the very fact of the existence of this type of paradox, which is still conventionally called the chicken and egg paradox.

So what is the correct answer?

Well, out of all sorts of interesting things, I would advise you to read whether or or The original article is on the website InfoGlaz.rf Link to the article from which this copy was made -

Well, it is obvious that in the process of evolution, the egg from which that chicken appeared first should appear. I think the egg came first. Yes, and the question is asked in a completely childish way. We must ask the question, who is the ancestor of this chicken. Over millions of years, species have evolved, genes have mutated. New species appeared, and some died out.

And here you have a question: did the chicken or the egg come first? Well, I’m right, it’s childishly naive. It's like it's a matter of a couple of hours. Here is a chicken and it will produce an egg, or an egg and it will produce a chicken. Question on children's development and imagination. In adults, uneducated and unread people, on the contrary, it “may” click and jam.

There is still a debate about what came first, the egg or the chicken. Scientists, philosophers and ordinary people have pondered this question for a long time. This is a mystery: a vicious circle, because if first an egg appeared, from which a chicken subsequently hatched, then there must have been a chicken that laid the original one.
