  Without going into the dilemma of chicken and egg, how can we... &nbsp; Too often we hear the use of the term 'chicken and egg' to describe a dilemma or paradox, where the occurrence of both A and B are dependant upon the existence of each other as a pre-condition.
Not very surprisingly, too often this term is also used as an excuse in many&nbsp;loosely constructed&nbsp;arguments. Which one existed first, chicken or egg? Like it or not, there is actually an absolute answer to this question. It wouldn't be so hard to realise that&nbsp;the world must have had an egg&nbsp;before we had a chicken if we think logically, carefully and scientifically.&nbsp; Modern science theories tell us that all living things today are&nbsp;products of generations of evolutions from single cell organism.
The first chicken on earth, like any other creature, must have come from a close species, probably some kind of bird-like being.&nbsp; Let's name this 'bird' a 'pre-chicken' for the sake of this discussion.&nbsp; The difference between a chicken and a pre-chicken is arbitary and is of no importance. Regardless of&nbsp;the criterion we use to differentiate a chicken from a pre-chicken, there is always going to be a boundary that we have to draw between these 2 species.
Now, one day a pre-chicken must have produced a chicken egg, before&nbsp;the first chicken in the world can be hatched. Of course, you can argue that this egg might not necessarily be a chicken egg. However, such argument would have ignored the fact that a non-chicken egg would have produced something else, probably another kind of pre-chicken,&nbsp;instead of a chicken. Based on this simple yet conclusive deduction, we can very confidently claim that an egg must have existed before a chicken.
Chicken and egg, it's far from being a dilemma!
