He began bringing her tea. He began arriving early, leaving late. He began, she noticed, adjusting his collar when she looked at him—a small, unconscious display. She recognized the gesture from a hundred courting species. What she could not decide was whether she was meant to be the chooser or the prize.
The trouble with Darwin’s theory, Clara thought one night as she walked home under a sky clotted with stars, was that it assumed desire was legible. But in humans, the ornaments were not always feathers. Sometimes they were kindness. Sometimes they were silence. Sometimes a man with a fine jaw and a second-rate mind would win, while a shy naturalist with a brilliant one would lose, because the criteria were never fixed. Sexual selection was not a ladder; it was a river, constantly shifting its banks.
The silence between them lengthened, and in it Clara heard the descent of something—not love, exactly, but the love of knowing her own mind. Darwin had written that the female’s preference could shape a lineage across millennia. He had not written that the hardest preference was the one that refused the obvious ornament in favor of an invisible, unfinished future.
