PS. It'd be easier to seriously discuss your question if you reframe it to state exactly what you mean instead of random. If you mean "undirected" or "unguided" or "undesigned" or whatever.
I meant random.
As I remember the theory, survival of the fittest only applies after the advent of some random mutation based change.
Given that understanding, I'm certain I meant random. That's not to say you won't argue with my understanding, but is the understanding that I have.
