Four billion years, and it comes down to this: the runner sits on the edge of a bed at three in the morning, terrified to move, because the whole race is now asleep on its forearm.
We have opinions. The lungfish, who first gambled on air, thinks the little one breathes too fast. The shrew who hid from the sky-death in a burrow of leaves keeps counting the ten fingers, the ten toes, tallying survival gear as she always did. And the woman who kept the fire through the long dark, who slept in shifts so the coals would not die, she recognizes this.
The vigil. The refusal to look away from the flame in case it goes out.
But look what we made possible. The runner is not afraid of cold. There is a machine humming that keeps the whole den warm, effortless, all night. No wolves at the door. No famine winter to outlast. Nobody has to be buried. The runner's only job, the only one, is to sit very still and hold the smallest of us and be frightened of the wrong things: a slightly odd sound, a hiccup, whether the head is supported correctly.
We who watched half our children go, we cannot stop laughing at the luxury of that fear. Worry about a hiccup. Please. Worry about a hiccup forever.
The new one opens its eyes. Unfocused, ancient, brand new. Every crawl and hide and crossing and buried seed we did not eat, all of it folded into this one drooling, blinking scrap.
We go quiet now. All of us. The whole line leans in to watch the runner do the oldest thing there is.
They lift the baby a little higher, and they smell its head.
That was the finish.
Well run.
