Evolution is neither random nor designed. You're presenting a false dichotomy. Natural selection is exactly what it sounds like: natural (as in natural, not designed) and selection (as in non-random).
Not really. Darwinian evolution relies on random mutations as the engine of change. No random mutation, no evolution. NS acts after RM rears its ugly head. Natural selection alone gets you black moths instead of white moths in heavily polluted forests. That's it and for NS to do even that alleles for white and black moths had to be a precondition.
So what is this "third way" you are implying. If something in not designed and not random - what is this third way you are talking about. If selection is not random than who or what is doing the selection? Your statement really makes no sense - are you claiming nature evolved the ability to select? How does nature perform the selection?
Like I said - if it is not random - than who or what does the selecting (please don't say nature)
Natural Selection is an observed process (in the past tense), not a force of power.
