Which came first, the chicken or the egg?
This question appears regularly in the question file, so let's take a shot at it.
In nature, living things evolve through changes in their DNA. In an animal like a chicken, DNA from a male sperm cell and a female ovum meet and combine to form a zygote -- the first cell of a new baby chicken. This first cell divides innumerable times to form all of the cells of the complete animal. In any animal, every cell contains exactly the same DNA, and that DNA comes from the zygote.
Chickens evolved from non-chickens through small changes caused by the mixing of male and female DNA or by mutations to the DNA that produced the zygote. These changes and mutations only have an effect at the point where a new zygote is created. That is, two non-chickens mated and the DNA in their new zygote contained the mutation(s) that produced the first true chicken. That one zygote cell divided to produce the first true chicken.
Prior to that first true chicken zygote, there were only non-chickens. The zygote cell is the only place where DNA mutations could produce a new animal, and the zygote cell is housed in the chicken's egg. So, the egg must have come first.

The experts looked at the evidence in the long-standing debate over which came first - the chicken or the egg - and opted for the egg.
Professor John Brookfield, a genetics expert from Nottingham University, said the first chicken must have started out as an embryo in an egg.
This means the organism in the eggshell would have the same DNA as the chicken.
He explained that the reason was due to the fact that genetic material does not change during an animal's life.
Professor Brookfield said: "The first living thing which we could say unequivocally was a member of the species would be this first egg, so I would conclude that the egg came first."

Theres a simple easy answer to this question and its the egg. Lets examine this issue a chicken couldnt have just came out of nowhere it had to come out of something so there we go the egg but wait the egg in that case didnt come from a chicken which is possible maybe the chicken was the evolution of the egg and if this theory is true that means that us humans may one day involve into something else.
Ah, The theory of evolution might be true it does add up...

In religion I believe it is the chicken,but in science it is an egg.
