Which came first, The chicken or the egg?

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. \n\nChickens 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. \n\nPrior 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.

Well, the chicken has evolved from a previous species. That species wasn't really a chicken, but it laid a mutated egg, which was a chicken. So, the egg came first.

The egg. Dinosaurs lived before birds and they layed eggs. Therefore the egg came before the chicken. :)

its the chicken which came first\n\negg is the method of reproduction\n\nnow u may say "From where did the chicken come?"\n\nits the course of evolution\n\nfinally\nchicken came first\nand found a method of reprodution\nthat is the EGG

The egg came first, because before there were any chickens at all, there was the species that mutated/evolved into the chicken (some sort of dinosaur, no doubt). That species was invariably an egg laying creature, and therefore, there were eggs long before there were chickens.

Just depends on what you believe in.  If you believe in Adam and Eve then you believe the hen probably came first.  The bible states that god created everything in 7 days.  \n\nIf you believe in the egg first you believe in evolution.  The egg was probably a mutated form of a dinosaur.  The creature probably didnt look much like a bird, but over millions of years the thing evolved into a chicken

My guess: chickens evolved from animals who breed via eggs, so eggs were first. Like there was one animal similiar to a chicken, that one day dropped an egg, and out of the egg came the first chicken. Or something like that...

We don't actually know. If the chicken came first, an egg was needed to hatch into that chicken in the first place. If the egg came first, a chicken would be needed to hatch an egg. There is no definite answer (yet anyway).

You mean ...what came first...Chicken or Egg...?

From the bible,especially the book of Genesis which talks about creation, We have not been told that God created an egg but all birds and from there it is the bird that layed the egg therefore, it is the chicken which came first and we cannot doubt that.

the chicken came first becuse the origin is the living thing's,so if the egg come befor there is No one going to hatch it .

Reptiles were laying shelled eggs for millions of years before some of them evolved into birds - and chickens came even later than that. So, by the time the first chicken laid the first chicken egg, eggs were already ancient. If your question is supposed to pertain only to chicken eggs, then obviously a species and its reproductive cells evolve simultaneously. Neither of them can exist before the other.

The egg.\nBefore chickens evloved into chickens, they were some other species that laid egss.\nOf course, if you are a creationist, you'll dispute that.

A team made up of a geneticist, philosopher and chicken farmer claim to have found an answer. It was the egg.\n\nPut simply, the reason is down to the fact that genetic material does not change during an animal's life.\n\nTherefore the first bird that evolved into what we would call a chicken, probably in prehistoric times, must have first existed as an embryo inside an egg.\n\nProfessor John Brookfield, a specialist in evolutionary genetics at the University of Nottingham, told the UK Press Association the pecking order was clear.\n\nThe living organism inside the eggshell would have had the same DNA as the chicken it would develop into, he said.\n\n"Therefore, the first living thing which we could say unequivocally was a member of the species would be this first egg," he added. "So, I would conclude that the egg came first."\n\nThe same conclusion was reached by his fellow "eggsperts" Professor David Papineau, of King's College London, and poultry farmer Charles Bourns.\n\nMr Papineau, an expert in the philosophy of science, agreed that the first chicken came from an egg and that proves there were chicken eggs before chickens.\n\nHe told PA people were mistaken if they argued that the mutant egg belonged to the "non-chicken" bird parents.\n\n"I would argue it is a chicken egg if it has a chicken in it," he said.\n\n"If a kangaroo laid an egg from which an ostrich hatched, that would surely be an ostrich egg, not a kangaroo egg."\n\nBourns, chairman of trade body Great British Chicken, said he was also firmly in the pro-egg camp.\n\nHe said: "Eggs were around long before the first chicken arrived. Of course, they may not have been chicken eggs as we see them today, but they were eggs."

the chicken came first as each animal came first and then their children if not than who came first  an adult human being or a child , an adult reptile or a child reptile , a bird or an egg?
