The Chicken May Have Come Before the Egg 341
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."

Putting aside extremely rare mutations in DNA (usually only caused by nuclear anonmoly), whatever DNA you have when you are born, you have when you die.
Life forms do not mutate/evolve/ during their lifespan; the mutations occur at the DNA copying phase when they are creating the next generation.
As such - the egg (IE embryo) came first. It is totally fundamentally impossible for the chicken to come first, because the chicken came from an embryo.

Specifically, the Bible states fish were created first, birds of the air second, and mammals third, which may roughly line up with evolution, if you're supposing birds evolved from dinosaurs, and dinosaurs came out of the seas, and mammals came along after the dinosaurs left the scene...
Kinda lines up; weird, huh?

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.

Once again, the Bible was right. Sadly, science doesn't even agree with itself, so there are many who are going to disagree. Personally, I don't find this "evidence" to be particularly compeling, but then I'm no longer the blind faith in science type. Science will never prove anything conclusively because it's a game where they continually move the goal posts.
It boils down to this: God made chickens and those chickens laid eggs. If you believe in macro evolution (I do not), then it's just a type of heap paradox, and therefore subjective.

I work in science labs, and the above is why half of scientists absolutely refuse to talk to journalists while the other half punches them on sight. The only time I did talk with them, I ended up on prime-time falling on my ass (slipping on ice, yup, that's the segment they kept).

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?

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:

The word evolution is a very elastic word. If the world and everything in it is a product of time and chance, then it specifically contradicts the Bible. Anyone who does not believe in God, can offer no explanation for what exists, other than time and chance.
Only a belief in God can offer purpose and meaning for your life. If Carl Sagan was right, if the cosmos is all there is and ever will be, then there is no meaning to life. If there is no God beyond the universe, (one verse) then life truly is "a tale told by an idiot signifying nothing".
Suppose someone gives you a gift, a package. You open it and find a beautiful but complicated device or appliance. Is your first thought to determine when or how it was made? Probably not. Foremost, you would like to know who gave it to you and why. Hopefully it comes with some instructions telling you what it is good for and how to use it. You might ignore the instructions and try to figure it out on your own. In doing so, you could damage or totally ruin the gift.
God gave you the gift of life and wants you to operate this life correctly in his beautiful, complex universe. Doesn't it stand to reason that he would have included an instruction manual? I believe this instruction manual is the Bible, a very unique book. In it he tells you not only how to operate this thing called life, but also why he gave this life to you in the first place.
He gives a lot of detail, but the bottom line is that he loves you and created you in such a manner that you can love him in return. Ask your stepfather and friends WHY they believe in God.
