The Chicken or Egg problem had been solved by a group of British genetic, a philosopher, and a egger. They say that they have solved one of the world's most ancient problems: What came first - the chicken or the egg? The answer: the Egg. The reason is the fact that the genetic material does not change in the chicken life course, so, the first bird existed is what we called today the chicken. Events most likely happened in a pre-historic must have happen earlier as a Chicken's fetus inside the egg. Professor John Brookfield, an expert for evolutionary genetics in the Nottingham University said to the I.P news agency, that the thing is quite simple. The organism living inside the egg, must have had the same D.N.A of the chicken it evolved to eventually. Therefore The first living thing you can say about it, that first it was an egg. To this conclusion reached his associates: Professor David Papiano from King Collage in London, and the chicken farmer Charles Barnes. Professor Papiano, and expert in the philosophy of science, agreed that the first chicken must have been hatching from an egg, which proves that there were chicken eggs before there were chickens. The simplest explanation is that a chicken can only hatch from a chicken egg, but a bird that isn't a chicken, can lay an egg that a chicken will hatch from it. That's the way evolution works. "If from an egg some sort of an animal lay, a chicken comes, that egg is chicken egg and not the animal-egg.", that what Professor Papiano said and repeated: If a kangaroo would lay an egg, and an Ostrich would hatch from it, it would be an Ostrich egg, and not a kangaroo egg. That's the answer to the ultimate "what came first?" question.
