Yeah, I see what's happened - I wasn't suggesting that you believe that to be the case: what I was saying was that when you used the example of birds vs. fish to illustrate people who don't fully grasp the concept of Evolution - I didn't feel that the analogy worked for the reasons I specified. Essentially I felt the part where you said
Would we say that birds are better than fish or vice versa? Don't either of those statements sound absolutely ridiculous?
was superfluous as I don't think it's a sentiment that even needs denouncing. I've never heard anyone use that as an example of evolutionary one-upmanship as it obviously does not apply in either instance. I think this goes back to my earlier point which you highlighted:
I think this applies to this whole discussion because the word Evolution in most people's minds comes with a capital E. It's a word with pretty strong connotations that tend to obfuscate any use of the word that doesn't hark back to
On the Origin of Species. Seeing as the crux of your argument is based around:
I would have thought a more appropriate analogy would be that of language. The grammar and speech sounds that Shakespeare had at his disposal were not all that different to what English speakers have today despite a gap of four centuries or so; and in that time there have been many cultural changes and changes in styles, fashions, politics, population etc. However the nuts and bolts of English are largely unchanged - especially with regard to speech. As someone has already alluded to there are a finite amount of physical articulations a human can make to produce speech sounds and until our bodies fundamentally change that will continue to be the case.
Bearing all this in mind - many things about English may have changed since Shakespeare's day, but has it improved? Or is it just new? Can we confidently say that after four centuries we have found a writer to kick Bill's arse?
You see what I mean? I would have thought something like that would support your argument in a context more befitting music. It also circumvents the whole problem with the E-word. Humans have not evolved in the last 400 years. Evolutionary steps in that sense are tens of thousands of years apart. We have changed, yes. Grown, learned, developed, built, nurtured, created, imagined, realised, pioneered, explored . . . all of these things. I just feel the E-word is too strong when talking about less than a century of popular music. Adaptation, perhaps; but then I'm just nit-picking again.
