Today, I will tackle the conundrum of Which came first:  the chicken or the egg? This is an age-old dilemma, confounding early philosophers.  The core argument takes the form of a catch-22.  All chicken hatch from an egg.  Hence, to have a chicken, one must first have had an egg.  But chicken eggs need to be laid by a chicken.  Hence, to have an egg, one must first have a chicken to lay it.  Phrased this way, this question does not seem to have a good solution.  Nevertheless, evolutionary biology has been able to resolve the issue with a correct but perhaps unsatisfactory answer.
