chicken or egg

this is a million dollar question from our earth existance and no one knows the exact answer.this question is like,which one is first ,seed or tree. The chicken or the egg causality dilemma is commonly stated as "which came first, the chicken or the egg?" To ancient philosophers, the question about the first chicken or egg also evoked the questions of how life and the universe in general began. Cultural references to the chicken and egg intend to point out the futility of identifying the first case of a circular cause and consequence. It could be considered that in this approach lies the most fundamental nature of the question. A literal answer is somewhat obvious, as opposed to the logical fallacy of the metaphorical view, which sets a metaphysical ground on the dilemma. So, to understand its metaphorical meaning better, it could be reformulated as follows: "Which came first, X that can't come without Y, or Y that can't come without X?" An equivalent situation arises in engineering and science known as circular reference, in which a parameter is required to calculate that parameter itself. Examples are Van der Waals equation and the famous Colebrook equation. Another example is the problem of calculating the required thickness of a roof -- we must first know the weight of the roof itself, which is possible only by already knowing its thickness. The problem is solved by initially assuming the parameter and by repeated iterations converging towards finer values. Responses to the dilemma: In biology, the term egg is biologically ambiguous and the theory of punctuated equilibrium, for example, does not support a clear division between the egg and the chicken and the closest ancestors of that chicken. Both of those factors tend to contribute to the circular nature of the question (causing problems similar to either a hasty generalization or a fallacy of definition). Below are a few different definitions that could be assumed and their logical outcomes. If the egg is not necessarily of any specific type: Then it could be said that the egg came first, because other animals had been laying eggs long before chickens existed, such as the dinosaurs. In biology, egg is used as a general term in this way. If only an egg that will hatch into a chicken can be considered a chicken egg: Then a re-consideration of the original question suggests: Some animal other than a chicken laid the first chicken egg which contained the first chicken. In this case the chicken egg came before the chicken. In reality, many scientific theories suggest that this would not have been a simple event. For example, the theory of punctuated equilibrium theorizes that the actual speciation of an organism from its ancestral species is usually the result of many mutations combined with new geographical surroundings, called cladogenesis. If only an egg laid by a chicken can be considered a chicken egg: Then a re-consideration of the original question suggests: The first chicken (which hatched from a non-chicken egg) laid the first chicken egg. In this case the chicken came before the chicken egg. Again, this would not necessarily be a straightforward event. Science and evolution: Evolution states that species change over time via mutation and selection. Since DNA can be modified only before birth, a mutation must have taken place at conception or within an egg such that an animal similar to a chicken, but not a chicken, laid the first chicken egg.In this light, both the egg and the chicken evolved simultaneously from birds who weren't chickens and didn't lay chicken eggs but gradually became more and more like chickens over time. However, a mutation in one individual is not normally considered a new species. A speciation event involves the separation of one population from its parent population, so that interbreeding ceases; this is the process whereby domesticated animals are genetically separated from their wild forebears. The whole separated group can then be recognized as a new species. The modern chicken was believed to have descended from another closely related species of birds, the red junglefowl, but recently discovered genetic evidence suggests that the modern domestic chicken is a hybrid descendant of both the red junglefowl and the grey junglefowl. Assuming the evidence bears out, a hybrid is a compelling scenario that the chicken egg, based on the second definition, came before the chicken. Theology: Judeo-Christian writings indicate God's creation of birds along with the rest of the universe. The Judeo-Christian story of creation describes God creating birds, and commanding them to multiply, but makes no direct mention of eggs. According to Genesis 1: 19 And there was evening and there was morning, a fourth day. 20 And God said, Let the waters swarm with swarms of living creatures, and let birds fly above the earth in the open firmament of heaven. 21 And God created the great sea-monsters, and every living creature that moveth, wherewith the waters swarmed, after their kind, and every winged bird after its kind: and God saw that it was good. 22 And God blessed them, saying, Be fruitful, and multiply, and fill the waters in the seas, and let birds multiply on the earth. In indian writings, creation of birds (and other life forms) by God through superhuman beings is stated in Puranas and Dharmasastras. Examples: There are many real-world examples in which the chicken-or-egg question helps identify the analytical problem: A graduate can't get a job because they have no experience, and can't get experience because no one will give them a job. (This is also an example of a Catch-22.) Companies find it difficult to introduce new consumer media formats, such as audio recording formats. Most consumers won't buy players for the format until there are many recordings to play on those machines, but record companies won't offer most of their recordings in the new format until many customers have the players. The same scenario applies to video recording formats, video game console systems, and computer systems. An actor cannot join the actor's union unless he has played a role in a union film, but a non-union actor cannot get a role in a union film because he isn't in the union. In the popular Christmas song, it is stated that 'The Snowman brings the snow', but how did the Snowman originally get there. source:http://en.wikipedia.org/wiki/Chicken_or_the_egg

chicken

Both..lol. Sorry I don't have a logical answer for this one! If I had to pick I would say the egg.

Hi Rrenwa! Welcome to Mylot! I think the egg cell came first. I mean, from the embryo, came the egg with shell and then the chicken.~~lol Happy Posting! Enjoy Mylot and Happy Earning! And please check the "guidelines" and "about mylot" situated on this page below..for a great successful kick start in Mylot. Have a great day! (^^,)

hi brod, this is an old question, but i guess the egg comes first.

the chicken...
