The Big Idea: David Walton
Zombie books just aren’t creepy enough.
They’re exciting, don’t get me wrong. When some drooling dead guy is breaking down your door to sink his teeth into your flesh, it’ll get your blood pumping. But the thing is, he’s dead. He’s not a person anymore. You can shoot him in the head and not even feel guilty about it.
But what if the zombies weren’t mindless? What if they were smarter than you? What if you let them into your house because you didn’t know there was anything wrong, because they didn’t even know they were zombies, and when they stabbed you in the back and infected your family, they truly believed they were doing the right thing?
My zombies aren’t really zombies at all, not in the classic undead sense, although they’ve been infected with a fungus that sends microscopic tendrils to set up shop in their brains. The fungus doesn’t turn them into moaning, decaying corpses, though. It’s much more subtle than that.
At first, it even seems to be beneficial. The fungus streamlines certain pathways of the brain and makes the hosts smarter, with better memory and learning ability and communication skills. Researchers think it could cure Alzheimer’s and dementia. Kids start taking it as a drug to do better on their exams. But the more beneficial the fungus appears, the more committed its hosts become to protecting it and spreading it to every human on Earth.
And why wouldn’t they? It’s a good thing, right? And if they have to kill anyone that gets in their way, that’s just what’s best for humanity. Or for the fungus. Whatever.
My zombie horde is spreading the plague on purpose, and they’re smarter than you are.
I first thought of this idea when I heard the suggestion that from an evolutionary perspective, wheat is the most successful organism on Earth. After all, wheat has taken humans that used to roam wild and domesticated them, getting them to spread its seeds all over the globe, and then enslaved them to weed out any competing plants and eradicate pests. All so stalks of wheat can grow tall and strong by the trillions.
It’s an amusing notion, and it’s not exactly wrong. But I realized that fungus is even better suited to using humans than wheat is, not because we want to eat it, but because fungus already directly manipulates animals to spread its spores. The zombie ants are the famous ones, of course (go watch the Planet Earth video if you don’t know what I’m talking about), but there are various other ways that fungus subverts animals to do its bidding. And fungus is smarter than you think — some single organisms create vast networks of microscopic tendrils that spread through an entire forest and pass information about where the moisture and nutrients are, basically acting like a giant Internet. Or a giant brain.
So what would you do, if there was a drug that could make you smarter? Or cure your dad of Alzheimer’s? No need to be squeamish about a little fungus living in your brain — you already have trillions of microorganisms living in your mouth, throat, stomach, lungs, and all over your skin. You won’t feel a thing. It’s a simple choice, really, given all the problems you have in your life. There’s not much at stake: just the free will of every human on Earth.
