Antecedents fared less well (since Juke was a variation become his own theme), upstaging all fellow players in the Mega-continents Cre-volutionary farce: mugging, posturing, pulling focus, smacking outsize lips or gnashing ill-adapted teeth (incisors never rivaled those of bona fide predators), lumbering toward the day their spawn would strut.
Meanwhile, the forgotten pair, those supernumeraries, so to speak, of primate Primogenitry, they who wandered off in search of a less vainglorious path, a less aggressive co-existence, a less pernicious approach to meeting their daily needs, accordingly shrank got littler. Not all at once, naturally; offspring for several generations retained the Juke-line size. But as the concept less became ingrained (then adopted as an axiom) those who put it into practice gradually grew diminutive. Which is not to say their gray matter similarly dwindledat least with respect to aptitude and complexity. Quite the contrary; smarts were due to neuro-circuitry, not to skull capacity. Mass, as density, held significance; mass, as bulk, was extraneoustherefore Juke & Ilk were no more on or off the ball potentially than the couple they saw fit to leave behind. Animal protein no doubt changed the grist for mental milling, but the gist remained equivalent for meat-eater and vegetarian alike. Not that either camp produced, at this stage, mental giants. Apes, both Great and Lesser, trudged through their existence, knuckles dragging, wits as razor-sharp as barbells for a long, LONG while. Still, development proceededat a hamstrung turtles clipas two, of a once-identical species, shuffled toward a showdown.
