Yes, I know a thread with the same title was just locked, but I hope this one will be more intelligent. I would like YOUR opinion, and an explanation of why you see it that way. I myself would have to say the chicken, because of evolution, it could have evolved from a different bird, so it wouldn't be an actual chicken egg, it would be a different species' egg, but the first chicken came from it.

The ovaries of the pre-chicken could have contained the ovocledidin-17 and used this to produce the first chicken egg. Could it not?


No, because it would have been observed in the remains of the eggs of previous species. This is how scientists know that it is a unique protein.

Sorry for DP, had to refresh and it sent my post before I was finished writing.

It appears that you aren't reading the mass of my statements


No, I'm reading them. They are just pointless because they are semantic musings which are attempting to deny a proven scientific study. If you truly understood the implications of this study then it would seem to me that you wouldn't bother with half of what you are saying. This is why I get the impression that you do not fully understand the publication, or perhaps even the finer workings of evolutionary biology.

I do not say this to be offensive, I say these things because as someone who does understand and study these things it seems painfully obvious to me that an understanding would negate the basis of your argument and thus you would not even attempt to propose such things as you have.

Why must you assume that the chicken was existent and then it evolved it's abilities?


The new traits would have come into existence with the new species, not after.

Let me see if I can explain.

Notchicken lays notchicken egg, inside notchicken egg is a baby with new traits making the baby a chicken, but the egg itself is still like the notchicken's. So the egg itself is lacking what makes a chicken egg, a chicken egg, but what's inside the egg does not.

Thank you for elucidating that for me Mage, I often have trouble putting concepts into simpler and concise terms.

Before I go on I would like to point out that I have structurally disassembled your arguments. Leaving a lot of my questions unanswered even if you find them ridiculous only spawns gaping holes in your argument. It appears as though you are ignoring challenges. Just a friendly reminder to continue to deconstruct all opposing views.

No, because it would have been observed in the remains of the eggs of previous species. This is how scientists know that it is a unique protein.


And they did this research? May I see the evidence?
From the sources I have read, the scientists were merely looking at the structural construct of an eggshell. It appears the media transformed it into a chicken first scenario.

And again what evidence is there that this figurative scenario took place? This presumption seems to depend on the idea of your personal thoughts. Why would the chicken only arise from an unrelated egg? This seems to relate back to one of my earlier ignored queries. If the egg is birthed by another pseudo-chicken yet contains a chicken, is it a chicken egg?
Or, does the classification of the egg lie in the animal that lays it?
The semantics are key to certain questions. Especially those which have been introduced into the common vernacular.

If you say so. But I'll play along with you. You want structural disassembly, even of extraneous and irrelevant comments? Here we go. (for the last time, because I really loath repeating myself)

Leaving a lot of my questions unanswered even if you find them ridiculous only spawns gaping holes in your argument. It appears as though you are ignoring challenges. Just a friendly reminder to continue to deconstruct all opposing views.


No, because most of your questions are irrelevant in light of the facts, which are all I have argued for here. Any other position, no matter how semantically pleasing, is irrelevant in light of evidence and as such it is pointless to address them. This is why I have refrained from dissecting your position piece by piece and in it's entirety until now.

Also, standard debate format is not the dissection of your opponents position piece by piece but to address the primary issue, or the opponents position as a whole.

And they did this research? May I see the evidence?

Attached to the article was the scientific paper which was published. I also looked it up elsewhere the other day to see any more articles on the issue. As was stated in the link, ovocleidin-17 is not only a protein necessary in the formation of the chicken egg, but it is only found in the ovaries of the chicken.

It has also been discovered in several species which evolved from the chicken, and never in a species who evolved prior to the chicken. This indicates that this protein did not exist prior to the chicken. This information was all there for you look at.

And again what evidence is there that this figurative scenario took place? This presumption seems to depend on the idea of your personal thoughts.


Yet again, it is all there in the initial report, as well as the attached publication.

Why would the chicken only arise from an unrelated egg?


Evolution. That's how it works. This goes back to my earlier statement that it is rather obvious that you do not have a solid grasp on the functions of evolutionary biology. I believe Mage put it in the simplest terms for you.

If the egg is birthed by another pseudo-chicken yet contains a chicken, is it a chicken egg?


No, it's not. For the sake of clarification, and not to imply that such an extreme example takes place in nature: An eagle lays an egg. This would be an eagle egg. from that egg a chicken is born. This does not change the fact that the egg was an eagle egg. So the egg from whence the first chicken hatched was not a chicken egg. And now we have scientific proof of this.

Or, does the classification of the egg lie in the animal that lays it?


Yes. This is the point we have been trying to make clear to you for 12 hours. Thank you for finally catching on.

The semantics are key to certain questions. Especially those which have been introduced into the common vernacular.


Certainly they can be. However when you are arguing from a semantic position which is in direct odds with the facts it makes your position seem juvenile and fruitless, much to my ire. I know I have difficulty at times elucidating the facts but this particular conversation has been highly frustrating. I do hope that I have fully answered all of your questions because I cannot explain this any more clearly.

I thought it was already established that the eggs of the chicken's predecessor lacked the qualities associated with chicken eggs.

Why would the chicken only arise from an unrelated egg?


No it's not an unrelated egg, it's directly related. It simply lacks that final step that gives it the quality associated with chicken eggs.

If the egg is birthed by another pseudo-chicken yet contains a chicken, is it a chicken egg?


Using the notchicken analogy. If you took two notchicken eggs containing notchicken babies and one containing a chicken and separated the babies from the eggs, all three eggs would show as being notchicken eggs instead of two notchicken and one chicken. So the egg itself would not be a chicken egg, even if it contained a chicken.

im with chicken, u cant have a chicken egg unless a chicken lays it, unless you classify the egg of an animal as the animal that comes out of it.....then again, that might be the smarter way to classify eggs....but srsly, you guys take this topic too seriously

Cool. Thread ended, thanks guys! It's nice to see other peoples take on it, and that mutant gene thing actually is very logical, Thanks for the new view! No new posts please!

Did you really expect no more posts? Anyways my view is that the chicken came first somehow or someway because the chicken in the egg wouldn't have been able to survive the cold without the mom sitting on the egg to keep it warm. And the chicken in the egg wouldn't have been able to learn how to live without a mentor.

I thought I would sign up just to contribute to this thread. Gallus Gallus (aka the "Chicken&quot, as we all know, lays eggs. In order to figure out what "came first" we need to analyze the chemical makeup of an egg. Eggs, essentially, are composed of bound calcium. This calcium is bound together, in the case of Gallus Gallus, by a protein called ovocleidin. Ovocleidin is a member of a group of C type lectin-like proteins. In birds, ovocleidin and similar proteins have used to regulate egg shell formation. Chickens have ovocleidin, but geese have an ortholog, ansocalcin, and ostriches have struthiocleidin. There seems to be a bit of "wiggle room" in which protein is used in shell binding processes, which probably means that most of the sequence is free to mutate without a big affect on the nucleating function. Looking at it from a evolutionary PoV, the species before Gallus Gallus, the first birds, and the reptiles before them all laid eggs. The appearance with egg laying was not coincident with the evolution of ovocleidin. The first chicken that acquired the protein we call ovocleidin now by mutation of a prior protein also hatched from an egg.

In conclusion, to sum it all up, since egg laying began, animals have used mutations of those main [ancient] proteins to form their eggs. Chickens also use a variation of these ancient proteins, but the first chicken that "came to be", came to be from an egg, though a mutation, most likely also carrying this mutated ovocleidin.

To those that may ask, which came first, the egg laying animal or the egg, I would respond... the purpose of this thread was to answer "Which came first, the chicken or the egg", and that is what I have attempted to answer (at the best of my ability).

And, just as an addition, that MSNBC "article" is a load of BS. I usually do watch MSNBC, and have their app on my iPhone, but that article was completely unscientific. Like I stated above, you could not have Gallus Gallus hatch without the premutation of ovocleidin. MSNBC's article suggests that "The scientists found that a protein found only in a chicken's ovaries is necessary for the formation of the egg, according to the paper Wednesday. The egg can therefore only exist if it has been created inside a chicken." You simply cannot come to the conclusion the author of this article was making here because, as previously stated, all predecessors of Gallus Gallus laid eggs. The egg, in general, does not need ovocleidin. As I have stated, there are many other types of similar proteins used in similar birds' eggs, as well as mutations.

@kjak
Let me see if I'm following. The genetic mutation that made a chicken a chicken would have also had effected the egg. Thus the egg it came from if tested would have tested as chicken egg even though it came from the species one mutation away from being a chicken. Would that be accurate?

@MageGrayWolf well, if you were to "test" it, I would suppose it would show up as an egg of the animal tested, although with a protein mutation (ovocleidin). So, in a way, it would test as both the egg of the species one mutation away, and an egg of Gallus Gallus. Although, I would also suppose that the mutation of the ovocleidin proteins in the egg would come before the actual mutation that would form what we now know as Gallus Gallus, in a way forming the right circumstances for the evolution/mutation into Gallus Gallus.

I do not know why so many people ask this, and it's so easy! if you believe in creation God made animals so he did the first chicken egg rigth! and if you believe in evolution. birds evolved from reptiles so ...DID YOU REALLY THING THAT MILLIONS OF YEARS OF EVOLUTION WILL MADE A CHICKEN EGG FROM A BIG LIZARD???
