I guess it would also depend on what the definition of "chicken" is as well. Essentially there are different stages in the development of any egg, so just like the abortion issue...when does the "egg" become the "chicken". Before birth there is a "chicken" inside the egg waiting to unveil itself to the world, and in this respect the chicken and the egg are one and the same. Chickens evolved from changes or mutation in the DNA that produced the Zygote. So, by this thinking, yes, the egg would come first...but when can you effectively call a newly created species by a new name? In mammals one cannot easily detect the difference between the early stages of development of chickens, humans, elephants, etc...the list goes on. The chicken only becomes a "chicken" at the instance it diverges from the structure of other known lifeforms. If the species that first evolved into the chicken by means of fertilization was not known as a chicken (which is true), how would the observer know if the newly created lifeform would become a present day chicken? One cannot know because only at the instance it differentiates itself from other mammals it becomes "itself".

Now, assuming that the original species that created the modern chicken laid hardshelled eggs as well...would mean they would have to incubate it. The fact that that species had the "potential" to evolve into the chicken makes it part chicken itself, and thus if the new chicken is killed because of improper care it negates the possibility of the egg coming first. Since said species has "potential" to become a chicken it would effectively mean that the Chicken came first.

Eggs cannot breed eggs. As they say...only life can give life, and in the same way, only the chicken can give an egg!

Chicken wins


Wow...we really have too much time on our hands

Now that creature will lay and egg and the genetic change this time will cause the egg to contain the DNA of a chicken.



How on earth can a dinosaur lay an egg containing a chicken or a bird. That is absurd. I have never heard of a reptile laying an egg that has hatched something with wings, it is illogical.



It was probably more along the lines of... Feathers came first, then feathers with stubs, then more feathers and bigger stubs, lighter weight bones, etc. It didn't just come out and say "Baawk!", it evolved. Have you ever seen a walking catfish?

encarta.msn.com...

There are plenty of species today with strange, half-usable appendages on their bodies, or similar things that appear at first to be lame freak-of-nature traits but with a million years of reproduction could become functional. It also works backwards, for instance, a species that is gradually losing something - like a tail, for example.

Indeed, a t-rex didn't produce a chicken, but gradually certain types of dinosaurs became more and more birdlike until they became birds.

EDIT: I should add -- while many species of dinosaur became extinct, many simply evolved, and we are surrounded by them today.
