The chicken and the egg

Which came first: the chicken or the egg? It is one of the famous paradox that people have thought for hundreds of years.

Scientists in Sheffield and Warwick Universities found that chicken comes first by using a super computer to zoom in on shell-making process while a new shell is forming. They discovered a protein, OC17, plays critical role in shell-forming and is found only inside a chicken's ovaries. That means, therefore, the chicken comes first, they say.

But the chicken which has OC17 was once in an egg, so where did the egg come from? Is their discovery really an evidence that the chicken was the first? I think the egg came first, if I am to give an answer of this rather philosophic query. When the fowl evolved from reptiles, the gene was changed in a way that the offspring of "the last reptile" becomes "the first bird". In other words, at the very moment of evolution, the reptile laid an egg of a bird. So it is the egg that first carried the new genes of chicken. The beginning was the egg because it is the first form of new generation.

I'm very curious as to how other people think about this life's oldest question.
