I'm perplexed by Gibb Sahib's dismissal of the notion of evolution. There are countless instances of what is evidently the "same" tune existing in different versions, which must have come into existence through a process of some sort. If you don't call that process "evolution" why does that term not fit, and what do you call it?

Is the objection to that concept based on an understanding that "evolution" implies "improvement" in some respect? In the case of biological species it typically does imply improvement in their fitness for their particular niches, but not necessarily in any wider sense.
