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.
You didn't say "random mutation" before; you said "random natural selection".....
However, that clarifies your meaning so that I can frame my response in more detail. I've been feeling really ill for about an hour though, so I'm gonna go lie down. =(
If I recover, I'll be back!
