The Chicken May Have Come Before the Egg 341

Posted by samzenpus
from the that-settles-that dept.
Muondecay writes "The age old question of which came first, the chicken or the egg, has been tentatively answered. The verdict? The chicken, or rather a key protein needed to form the shell of the egg. The protein, called ovocledidin-17, was known to be involved in binding calcite molecules that formed the shells, but the mechanism behind this was unclear until now. The protein acts as a molecular machine, binding to nanoparticles of calcite and guiding them to begin self-assembly of the shell. This gives tremendous insight for developing methods of nano-scale self-assembly based on natural processes, as well as settling heated cocktail party arguments everywhere."

      Well it would have been soft eggs first. In some of these soft eggs, there would have been mutations in the DNA resulting in a slightly increased amount of ovocledidin-17. These eggs would then have slightly harder shells and likely a higher survival rate due to more durability. As time goes on, those mutations giving even more ovocledidin-17 and resulting in even harder eggs, become more dominant than those DNA strands without the mutation etc.

      At least, that's my understanding of how it all works...

      So the egg came first, later developing an evolutionary advantageous shell.

        If you're implying that the egg came first, you're wrong, but not for the reason you might suspect. The question is not about evolution of eggs or chickens, and pre-dates evolutionary theory. Originally it was probably a metaphysical question, how do you have a chicken that lays eggs without either a chicken or an egg? It never was about timetables, it was about where do things come from if they don't exist?

        "If there has been a first man he must have been born without father or mother -- which is repugnant to nature. For there could not have been a first egg to give a beginning to birds, or there should have been a first bird which gave a beginning to eggs; for a bird comes from an egg."

        Aristotle, (Isis Unveiled I, 428.)
        http://www.blavatsky.net/magazine/theosophy/ww/additional/ancientlandmarks/PlatoAndAristotle.html [blavatsky.net]

        With the your understanding, we can declare eggs the winner. But it still does not quell the anti-evolutionary forces which ask ok fine, which came first the dinosaur or the egg? The question can be rephrased for today's audience as: how do codependent traits arise? How can something irreducibly complex as the human visual system come from nothing?

        We know the answers to those questions, roughly speaking, just as we knew the answer to this one. But we didn't have a concrete explanation of just how that happened.

        In addition, the questino of chicken-egg primacy has always implied hard-shelled eggs, at least to my understanding. So reptiles and extinct species would not count. Hard shells came from the same place chickens did, at the same time, is the implication. Finding the protein means we have an explanation that hard shells are independent of an actual chicken. Many reptile species probably contain the ability to create this protein, but it is supressed or under-developed. Finding that would be the best way to put to rest anti-scientific rhetoric. The hard-shell egg probably came both before and after chickens, and we have just the one species left that has both chickenness and hard eggs.

        An updated version of the question is asked and addressed here, along the lines of your thought, but this is merely grafting modern terminology onto an ancient question and making it a concrete, rather than abstract question:

Maybe everyone who can tell the difference between a-protein-now-found-in-chickens and a chicken has long ago come to the conclusion that what came first was some animal different enough from a chicken that we wouldn't call it that, which laid an egg that contained an animal similar enough to a chicken that we would call it a chicken.

          What came first? The molecule or the cell? The prion or the virus?

          Not sure if you want real answers to those or not, but obviously the molecule, and evidence suggests the prion. However, with prions your question doesn't quite make sense because it's not like viruses descended from prions. Prions are simply "rogue" proteins which force proteins that they come in contact with to conform to the same secondary structure (usually beta folded sheets). It is thought that amino acid chains probably formed (perhaps without any necessary "function") early during the origin of life, and were quite possibly prion-like. Here's an interesting paper about it:

          Milner-White, E.J. & Russell, M.J., 2008. Predicting the conformations of peptides and proteins in early evolution. Biology direct, 3, 3. Available at: http://biology-direct.com/content/3/1/3 [biology-direct.com].

          And, obviously, since molecules are required to make cells (as cells are made up of molecules), the molecule would have to come first. There are some hypotheses about the origins of life suggesting that it is possible that most or all of of the biochemistry of early cells were in place before they even became cells. Here's a good starting point read about that:

          Martin, W. & Russell, M.J., 2003. On the origins of cells: a hypothesis for the evolutionary transitions from abiotic geochemistry to chemoautotrophic prokaryotes, and from prokaryotes to nucleated cells.

Available at: http://rstb.royalsocietypublishing.org/content/358/1429/59.abstract [royalsocie...ishing.org].

        This is mostly irrelevant. A "Chicken" is just a point in time of a particular leaf point in the tree of life. Whatever creatures that were part of that tree that laid the first "chicken" egg was still able to mate with the first "chicken". The point at which you call them "Chickens" is when they're no longer able to successfully mate (as a population) with other offshoots from the tree, or the original, larger, body.

        There's no hard point at which one species changes into another (which will confound your average creationist, who are constantly asking for there to be a sharp division between ancestors and child species), it's a gradual process involving thousands of mutations over many generations. Whatever laid the first Chicken egg was still a chicken, and if you go back far enough, it wasn't a chicken, so much as it was the ancestral node in the tree of life's species.

  • If one accepts the premise of natural selection based evolution, then the only possibility is that the egg came first.

    The first chicken would have been laid in an egg, whose parent was something other than a chicken (perhaps a bit more dinosaur like, reflecting its earlier origins).

    The paper as I understand it isn't showing whether the "chicken" or the egg came first, but rather, the original chicken-like organism (either a dinosaur or something earlier) or the egg it came in. These are actually two very di

Phew, that's certainly a relief, I was worried about mankind not having that to put in our time capsule for future generations to gawk at...

    On a genetic scale the egg formed long before the chicken -- like dinosaur egg long ago.

    But even on a more "recent" time scale the egg came first. For clearly a not-chicken laid an egg and from it was hatched a chicken. Of course this was unbeknown to the not-chicken, which simply thought, "you are one ugly not-chicken".

    To think otherwise would argue the the not-chicken did not lay eggs but rather gave live birth --which would not even be a bird. I'm pretty sure the Chicken isn't the missing link between Viviparous and Oviporous.

      Actually, the proto-chicken laid an egg which was also a proto-chicken. Eventually the proto-chickens crossed the threshold for which we would consider a chicken, but it's difficult to draw an exact line in the sand, because the entire chicken population evolved so slowly.

      It most certainly was not a spontaneous one generation change.

      In order for there being a conundrum, by egg must implicitly be meant a chicken egg. Now the question becomes one of defining that. Is a chicken egg an egg laid by a chicken (chicken first) or one from which a chicken will hatch (egg first)?

    • by jabuzz (182671)

      The problem with this is that the chicken is a cross between a Red Junglefowl and a Grey Junglefowl. As both these birds lay eggs, it is quite clear that the egg came *before* the chicken. Clearly while this is the technically correct answer that is beyond doubt to the possed question, it does not answer the wider question that was being posed.

      However even if you where to widen the question to which came first the bird or the egg, you would still get the same answer as eggs predate birds by some considerabl

    We're missing the bit about Evolution. Chickens and Eggs didn't appear, they evolved. What eventually became a chicken, was laying eggs long before a chicken walked the earth. In describing what defines a chicken, one attribute we can mention is that it "lays eggs". When doing the same with an egg, we cannot argue that a requirement is that it contains or came from a chicken. So, an egg is necessary for a chicken.

  • could you please explain the riddle of schrodinger's chicken?

    it laid an egg, and yet it did not lay an egg, and the egg, that may or may not exist, possibly hatched a chicken, which may or may not be the same chicken that laid the egg, because we don't know which came first, if either came at all. and then schrodinger killed the chicken, or maybe he didn't, and nobody knows what the hell he might have or might not have done to the egg, whether or not he killed the chicken, that may or may not have come firs

    Every kid knows the first eggs were put out by the Easter Bunny.
  • ... is the most absurd debate I have ever heard, it is analogous to asking, "which came first, the mother or the child?". Of course the chicken, which developed from another creature, came first in order to lay the egg.
