Fluke: Or, I Know Why the Winged Whale Sings

were certain things that you accepted if you were going to be a biologist, and one of them was that complex life was a process of evolution by natural selection, that you got a new species because the genes that favored survival in a certain environment were replicated in that species, selected by being passed on, often a process that took millions of years. You didn't put in your order and pick up a new species at the window. There was no cosmic fry cook, there was no watchmaker, there was no designer. There was only process and time. "How could you possibly know that anyway?"
    "I just know things by being in contact with the Goo, but I'm not far off. It might be less time – two hundred years."
    "Two hundred years? The whaley boys are definitely sentient by any definition, and I don't even know what the whale ships are, but they're definitely alive, too. That kind of complexity doesn't happen in that short a time."
    "No, I'd say the Goo has probably been here as long as three and a half billion years. The rocks around these caves are some of the oldest in the world. I'm just saying the whaley boys and the ships are new. They're only a few hundred years old because that's how long ago the Goo needed them."
    "The Goo needed them, so it made them to serve it? Like it has will?"
    "It does have will. It's self-aware, and it knows a lot. In fact, I'd venture to say that the Goo is a repository for every bit of biological knowledge on the planet. This, Nate, this Goo is as close to God as we are ever going to see. It's the perfect soup."
    "As in primordial soup?"
    "Precisely. Four billion years ago some big organic molecules grouped up, probably around some deep-sea source of geothermal heat, and they learned how to divide, how to replicate. Since replication is the name of life's game, it very quickly – probably in the span of less than a hundred million years – covered the entire planet. Big organic molecules that couldn't exist now because there are millions of bacteria that would eat them, but back then there were no bacteria. At one time the entire oceanic surface of the earth was populated by one single living thing that had learned to replicate itself. Sure, as the replicators were exposed to different conditions they mutated, they developed into new species, they fed on each other, some colonized each other and turned into complex animals, and then more complex animals, but part of that original living animal pulled back into its original niche. By this time chemical information was being exchanged – first by UNA, then by DNA – and as each new species evolved, it carried on all the information for making the next species, and that information came back to the original animal. But it had its safe niche, pulling energy from the earth's heat, sheltered in the deep ocean and by rock. It took in all the information from the animals that it came in contact with, but it changed only enough to protect itself, replicate itself. While a million million species lived and died in the sea, this original animal evolved very slowly, learning, always learning. Think of it, Nate: Within the cells of your body is not only the blueprint for every living thing on earth but everything that has ever lived. Ninety-eight percent of your DNA is just hitching a ride, just lucky little genes that were smart enough to align themselves to other successful genes, like marrying into money, if you will. But the Goo, not only does it have all of those genes, it has the diagram to turn them on and off. That seat you're sitting on may well be three billion years old."
    Nate suddenly felt something he'd felt before only when waking up in a hotel with the bedspread pulled up around his face: a deep and earnest hope, motivated by disgust, that in all the time it had been there, someone had cleaned the cast-off genetic material from it. He stood up, just for safety. "How could you possibly know this, Growl? It goes against everything we know about evolution."
    "No it doesn't. It completely fits. Yes, a complex process like life can develop, given enough time, but we also know that an animal that fits perfectly into its niche isn't pressured to change. Sharks have remained basically the same for a hundred million years, the chambered nautilus for five hundred million. Well, you're just looking at the animal that found its niche first. The first animal, the source."
    Nate shook his head at the magnitude of it. "You might be able to explain the
