[First, my apologies to all readers for the length of this post — I don’t like over-long posts myself, but in this case I felt it was necessary, precisely because the phenomenon I’m addressing is unfamiliar to most evolutionary thinkers, and often misunderstood.]
Coda: when I say “failure of inclusion”, I’m pointing out a very real phenomenon, not the trivial one you seem to think — also, I’m not saying that it’s something that “shouldn’t” happen. The example of inclusion you give of inclusion (modern coloratura) is mistaken. Coloratura is not in any sense a survival of melismatic singing, and their vague resemblance is trivial. As for the tradition of Gregorian chant, it has been lost forever. What the monks sing today is a hypothetical 19th-century reconstruction of a long-dead tradition, with interpretations that are total guesswork, some of which are demonstrably inadequate, and others almost certainly wrong. It’s no substitute for a living tradition — nevertheless, I, like most listeners, am grateful that they at least made the attempt, however impossible the resurrection. Moreover, the equal-tempered scale is fundamentally out-of-tune, something which our ears have gotten used to; but if you practice singing and playing in an in-tune tradition, such as Indian or Mideastern music (as I have), then you’ll hear JUST how out-of-tune a piano really is, and then, maybe you’ll begin to understand what has been lost in the Western tradition …yet I’d be the last to say that equal-temperament shouldn’t have happened, and that I need to stop loving Chopin, and deny my ability to “shift ears”, so that his music becomes plenty harmonious enough for me!! … but I won’t go on about musicology, for it gets into a lot of technical terms, and your knowledge of the subject seems limited, to say nothing of the risk of boring other readers in this forum. Instead, let’s go back to the far more important subject of agriculture. Its extremely destructive effects on average human happiness and well-being are brilliantly described by Yuval Noah Harari, in his book Sapiens, which I recommend you read, if you haven’t.
And when you talk about :
high rates of death and discomfort from illnesses, genetic conditions, and natural disasters, as well as infant mortality, inter-tribal rape, kidnapping, and slavery,
… then from my point of view, you’re just dishing out that same old, ancient old, civilized propaganda, with all of its “nasty, brutish, and short” bullshit about “primitive” nomadic tribal life …yes, they had a very high rate of infant mortality — and that’s about the only true statement in all that list of stereotypes… But high infant mortality (the most ancient means of checking overpopulation) doesn’t necessarily mean that older youths and adults didn’t have a high quality of life; and it certainly doesn’t support that baseless old stereotypical image of ancient tribal people dying like flies after the age of thirty or so… for all we know, early bronze-age tribal nomads may have had a much higher adult longevity than the average of later civilized peoples. Let’s not forget that it wasn’t all that long ago, geologically speaking, that all humans were nomads, and had been living in tribes for at least 500,000 years (by far the most stable form of social organization ever discovered by H. sapiens) … then, less than ten millennia ago, those who refused to become sedentary were progressively forced to live in ever-more disadvantageous and degraded conditions by pressure from civilized peoples and their armies. The logic of civilization’s ancient, endlessly-repeated, self-serving propaganda isn’t all that different from the old, post-civil-war white supremacist’s argument, which used to point out the (then-incontestable) fact that shoeshine boys are always black men … and propose that as evidence that most of these people are incapable of anything but menial work.
I hope you understand that I am NOT saying that these failures (or if you prefer, “limitations”) of inclusion shouldn’t have happened … the fact is, such failures, or limitations do happen, and they are all over the place, if you look with an open mind, and drop the assumption that evolution is always about something (conveniently undefined) called “advancement” or “progress” . Just one example out of many: in the Phaedrus
dialogue, Socrates warns against attempting to put any true philosophical teaching into writing, because writing inevitably distorts, and even betrays the living teaching (and, believe me, Plato is well aware of the irony…). Socrates never wrote anything; Jesus never wrote anything; Buddha never wrote anything; Lao-tse never wrote anything, until he was forced to … do you think all that is mere coincidence?
But again, I’m not claiming that this kind of evolutionary loss is something that needs to be fixed, or corrected. I don’t know if it’s even possible; and anyway, it’s beside my point. What I am saying, is that it’s something that is often overlooked, and deserves to be studied more, in an attempt to understand it … and that so far, I have found little or no mention (much less understanding) of it in any evolutionary theories, including Ken Wilber’s. My most general, basic point is that (unless I’ve missed out on a very important discussion somewhere) evolution is more subtle and complex than we have realized in any of our theories, so far. Should that come as a surprise?
{…The only possible exception I know of is Rudolf Steiner, who said somewhere that every evolutionary gain must be paid for with a loss (unless I’m mistaken… … I’m far from being a believer, or even knowledgeable about anthroposophy, but I do think the man had some amazing insights. }
