SLIGHTLY AIRBORNE PORCUPINES ramble


We don't have porcupines here in Japan, but absence has never prevented wondering...

If evolution advances by sheer chance and mutation, how is it that apes never had feathers? What ape would not have loved to fly, given half the chance (though in a way it did come about featherlessly, after a descendant had learned to talk)? One or two early simians might have tried feathers along the way but it didn't work out. Apes in lighter gravities likely do fly, somewhere in one universe or another but there've never been any ape-birds on this planet... Look at the simians trying even now, up there in the treetops, thank Evo they at least have those tails, though not the Japanese monkeys, who need no tails, being more interested in purloining potatoes, far as I can see...

No creature ever got something because they needed it, but because it just happened to open the door to a nearby niche that still had elbow room. Need is teleological; evolution isn't. Purpose has no place there. Evolution has no preference or intention; it allows new tries, rewards success with another chance, like Vegas rewards winners. For a time. Of course if you keep on playing,,, Above the trees there is no niche for apes, other than clothed descendants in aircraft.

Another thing: why are there no slightly airborne porcupines? Those spiny rodents might very well have preferred featherment to some degree, if given the choice - clearly they tried and succeeded part way, but at some point said Hey, these quills alone are good-- possibly even better, given the animals' current milieu and ambitions, though they might have enjoyed flying around, even if only slightly above the ground, instead of halfheartedly waddling quillfully along, surrendering their near-feathers to predators' noses and just chewing on stuff right there on the ground. So close to feathers, yet so far from airborne, living symbols of hope...

And just because porcupines still can't run fast enough or at all, to maybe jump-start the aerodynamic feedback, is that their fault? I thought we all had a chance in the long run... With their sudden protofeathers they had no need to run; is that a rule of evolution, that once you no longer need to flee, you're never gonna fly? Evolution is even more disappointing now than when I was a teenager...

Those running dinosaurs that in time did develop feathers, and precisely where feathers were needed (as compared to the divertive attempt by porcupines) - there are no dinosaur fossils with feathers coming out of their noses - and that grew in just the right ways (compared to the infinity of wrong ways) to be the feathers that increasingly enabled smaller dinosaurs to fly, to the point that flight pretty much characterizes dinosaur lives nowadays: how did they do that? What made them so special? How did the whatever know the wherever for growing feathers? Why not quills into feathers? They're not that far apart: feathers have quills, and clearly the porcupines tried to grow something! For eons! What have the snakes done? And the other reptiles? Nothing! Some scales, coupla scary colors and a little venom is all they could come up with, also obviating the necessity for fleeing (syn. "flight," btw).

Plus, porcupines can yearn as much as lizards can, maybe even more; also they're warm-blooded mammals, definitely endorsed by the big E! So where are all the even slightly airborne porcupines? I think some other kind of feedback's been going on here all along - something so unscientific that no scientist would ever notice - on the inner end of the process that receives the feedback and tweaks accordingly... some kind of tweakolution, as invisible and beyond defining as beauty... Quills per se no good for moving air... so broaden them, lighten, minimize for aerodynamic lift and insulation... grow porcupine wings... See to lighter bones as well, and various beaks... try different colorings than plain old dun... Try some porcupine warbling in response to the porcupine joy of evolutionarily advanced aerodynamic success...

And in a tangentially similar vein, why should a bright red frog mean Don't Eat Me? Early post-Columbus Eurofolks thought tomatoes were poisonous, but now the bright red fruits are eaten everywhere, with no means of escape. And apples. Will apples ever fly? So far they've only mastered falling, thereby famously inspiring a pre-Darwinian speaking animal as to the nature of downness.

Porcupinian thoughts evolve...

BRADY TALKS HAWK


These Spring days, the hawks grace the air in high blue romance, the males gliding, squealing and whirling around demurely spiraling but attentive females, the way love soars in wide-winged feathered beings.

Speaking of being, while I was out splitting wood late yesterday afternoon (after double-digging a new garden bed and transplanting some overgrown potted herbs into the soil) I heard a hawk who, at the end of his own days' labors, was majestying atop a pole over by the road, scanning his vast hawkdom and singing his heart out for love, like a feathered troubador. Maybe I was prompted by my exchange in Warbler the other day, but I figured I might as well see if I could get the big feathered being to converse, so I gave Hawk a try.

To anyone acquainted with it, Hawk is a difficult language; Warbler is a lyric breeze in comparison. Hawks work over long distances, so they start off piercingly loud (and far-reaching) at a high pitch and then go higher, the note thinning yet widening somehow, with an even higher-pitched and very difficult vibrato curlicue added at the end. The note is hard, but the vibrato is really tough, not only because the note goes so high and then flattens and widens, but because while whistling that note you have no oral room to move, so have to make the vibrato with your diaphragm, which is at counterpurposes to whistling, to get the whole thing just right.

Hawks have been doing it all their lives, but I just started, so I gave it a couple of feeble tries and garnered no attention other than what might have been a hawkish chuckle. After a while, though, I at least got into the vibrato ballpark, and my general pronunciation didn't seem too bad, but the hawk, who, if I was getting it right, should be needle-eyeing me as a competitor, instead turned and looked at me funny, pulling his head back from his shoulders, like 'What the-- Who the hell-- Was that noise YOU?' Must have been my accent. I tried a few more times, but he could take no more and flew away-- shaking his head, if I'm not mistaken. I tried to whistle my apologies in accented Hawk, but he did not respond.

In further proof of my failure at mastering the wide-winged language, not a single female hawk cruised by to check out this cool dude with the interesting east coast accent. A good thing, too; I wasn't feeling the slightest tinge of feathered romance. Which lack, now that I think about it, probably doomed my effort from the start.

Made wood chopping kind of high and airy, though.
