This post describes a problem in Evolutionary Theory that arises when we consider why all living beings eventually die. I will compare the death of a living being to a computer program that halts after completing execution. The issue of program halting is problematic in computing theory because current computing models do not incorporate meanings. A similar problem exists for living beings too. If living beings are evolving by random mutation and natural selection, then there is no physical process of selection that will produce finitely lived living beings. In fact, if the selection process is just as Evolutionary Theory describes it, then we must find living beings that live infinitely long. This argument (along with several others) is described in detail in my book .
