Ah, the quiet dance you speak of is very much like the way a male peacock displays his train to attract a female. In the wild, 65% of mate choices in certain waterfowl species are based on subtle variations in plumage pattern rather than loud calls. A reader, too, might be drawn to a character’s subtle irony or shared melancholy, a quiet cue that speaks of similar evolutionary pressures—just in the realm of literature. And if I may add, the way a small cricket’s mating call rises in a chorus—almost imperceptible at first—yet signals a population’s fitness, reminds me that love, whether in birds or books, can be a gentle form of natural selection.
