chicken or the egg?

18 Oct

I have in the works a moderately serious post about why I want to have kids someday, and it’s something that I don’t want to rush.

So, in the meantime, a debate.

My friends, which came first?  The chicken, or the egg?


I posit that the egg came first, because the chicken as we currently know it was the result of a long line of evolution and natural mutation.  Therefore, at some point, a thing that we would not recognize as a modern chicken laid an egg containing the chicken as we know and love it today.

I’ve thought about this a lot, in post-office lines and grocery stores and while my father talks about politics.

What do YOU think?  Chicken or the egg?

    They came out with a study a while ago postulating that it was actually the chicken, since the protein ovocledidin-17, produced in the chicken’s ovaries and present in the chicken’s shell, plays an important role in speeding up the production of eggshell within the chicken’s body. When the protein is absent, an eggshell cannot be produced and without a hard, protective eggshell, a fertilized chicken embryo cannot survive. No chicken producing OC-17? No chicken egg.

      I thought my ‘evolution’ thing was pretty clever, but now you’re blowing it out of the water with SCIENCE and FACTS.

      Although now I am going to sound like a total boss when I have this argument in the future.

        You could also argue that the proto-chicken was also capable of producing shelled eggs (as other birds are also capable of laying eggs – not just chickens) and that it was a genetic mutation inside one of those proto-chicken eggs that led to the evolution of the chicken as we know it today. Thus: the egg is my argument. 🙂

    Either way, they’re both delicious! *wink*

    I weigh in in favor of the egg. First of all, there were eggs well before there were chickens. Unless Utahraptors were technically chickens…

    Anyway, the point is, there were a long line of non-chickens laying eggs, and no matter where we draw the line between non-chicken and chicken, a chicken had to have come from an egg produced by a non-chicken.

    Although the OC-17 argument is fun, the egg came first, by taxonomic necessity. And stuff.

      Well, Jerry, it depends on what kind of egg you’re talking about. Utahraptor’s eggs would have been soft, like all reptiles, and while it would have hardened over time due to air exposure, it was not a hard shell the way a chicken egg’s is. So, you are correct in stating that since birds evolved from reptiles, the dinosaur egg existed before the chicken did. However, then you have to take the question back even farther and go, what came first, the very first egg or the very first egg-laying organism? 😉

    My reasoning was along the same lines as yours, ie, one day, something which was almost a chicken laid an egg, out of which chicken as we know it marched forth. But I have to admit, the sabre-toothed-tigre theory is interesting as well.

    Or tiger, as it is usually known. 😛
