what came first the chicken or the egg?

chicken

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 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. 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
