"randomness

It IS important to specify which sense you mean"

I am specifying that there is no room for this term in a discussion of evolution. Nothing that happens to make species change is ever random in that there will always be a cause. Mutations are never random, in spite of the ludicrous received-wisdom term "random mutations." Natural selection is the very opposite of random. "Random" is a term that is overwhelmingly used by people who just don't get evolution.
