5 Scientific Reasons a Zombie Apocalypse Could Actually Happen. What do you believe?

Asked by deepdivercwa55m (353points) January 9th, 2010

They found out recently that if you try to leave a little kid in a graveyard late at night, he’ll freak out. Even if you offer to leave him a gun to protect himself. Why? It’s because on some instinctual level, all humans know it’s just a matter of time until the zombies show up.

Our culture is full of tales of the undead walking the Earth, from our religions to our comic books. But, some sort of zombie apocalypse isn’t actually possible, right?
Right?

Guys?
Actually, yes. It’s quite possible. Here’s some ways it could happen, according to science.
1)Brain Parasites:
There are parasites that turn victims into mindless, zombie-like slaves are fairly common in nature. There’s one called toxoplasmosa gondii that seems to devote its entire existence to being terrifying.

This bug infects rats, but can only breed inside the intestines of a cat. The parasite knows it needs to get the rat inside the cat (yes, we realize this sounds like the beginning of the most fucked-up Dr. Seuss poem ever) so the parasite takes over the rat’s freaking brain, and intentionally makes it scurry toward where the cats hang out. The rat is being programmed to get itself eaten, and it doesn’t even know.
Of course, those are just rats, right?
How it can result in zombies:
Hey, did we mention that half the human population on Earth is infected with toxoplasmosa, and don’t know it? Hey, maybe you’re one of them. Flip a coin.

Oh, also, they’ve done studies and shown that the infected see a change in their personality and have a higher chance of going batshit insane.

2)Chances this could cause a zombie apocalypse:
Humans and rats aren’t all that different; thats why they use them to test our drugs. All it takes is a more evolved version of toxoplasmosa, one that could to do us what it does to the rats. So, imagine if half the world suddenly had no instinct for self-preservation or rational thought. Even less than they do now, we mean.
3)If you’re comforting yourself with the thought that it may take forever for such a parasite to evolve, you’re forgetting about all the biological weapons programs around the world, intentionally weaponizing such bugs. You’ve got to wonder if the lab workers don’t carry out their work under the unwitting command of the toxoplasmosa gondii already in their brains. If you don’t want to sleep at night, that is.

You may be protesting that technically these people have never been dead and thus don’t fit the dictionary definition of “zombies,” but we can assure you that the distinction won’t matter a whole lot once these groaning hordes are clawing their way through your windows.
So do you believe this scientific researches??

Actual Zombies by our own definition….........no I dont think so, but Zombie-like behaviour, sure why not.
Whether they would eat human Brains and infect others by biting them though is another thing.
I personally prefer Zombies to stay in the realms of films and books and stuff though.

There already is a growing army of zombies. We call them Meth heads. A Methamphetamine addict in the advanced stages has permanently changed their brain chemistry and presents with all the mental, emotional and physical charactaristics of a zombie.

Number of scientific reasons as of today: zero.

Science fiction? Sure. Mind uploading into a computer comes to mind. There are good science fiction books about it. Although these computers are not called zombies. Well, if they are running on Unix there might be a few defunct zombie processes pestering the processor.

I thought it was common knowledge zombies are already amongst us. Paris Hilton, Amy Winehouse,Sarah Jessica Parker,Barbara Bush,Pee Wee,Marylin Manson,Ozzy Osbourne,to name but a few. They’re all brain dead pug ugly individuals so surely they qualify.. don’t they? I don’t rate their chances highly of causing an apocalypse though. Tying their own shoe lace would be a challenge for these invaders. We could however put them in a kinda zombie zoo throw peanuts at them & so forth. Just an idea.

This is an excerpt from a Cracked article, isn’t it? It reads like something they would write.

Fun fact: if you stimulate the right parts of the brain of a rat, you can make it think it it’s full when it’s actually literally starving, or that it’s hungry when it’s about to burst. I’d speculate that what these “brain parasites” do to rats is similarly messing with the rats’ brains to give them certain stimuli the rats stupidly act on.
Humans on the other hand have some meta-cognitive awareness. That’s a term I just made up, to say people are aware of what happens in their minds. If you or I suddenly find ourselves having an impulse to climb onto a roof top and jump off, we’ll know that something odd is going on. We also probably wouldn’t climb onto a roof top and jump off just because we feel an impulse to. We’ll know it’s a bad idea.

I also wouldn’t be afraid of zombie lab workers creating zombie apocalypses because a brain parasite wants that to happen. That would require foresight on the part of the parasite, and as far as we know the only other life forms with anything that remotely looks like foresight are other vertebrates, and even they can’t make long term plans for the world.
Toxoplasmosa gondii are single-cell life forms. They don’t make conscious decisions. They definitely don’t make evil world domination plans. They don’t think ahead. They don’t think.
And if they did, controlling a scientific mind to use its knowledge, intelligence and creativity to find ways to bring about a brain parasite zombie apocalypse would also take much more intricate control than required to make a rat get itself eaten.

Γεια σου Δημήτρη! I don’t believe there is a way in reality for a healthy man to turn into a zombie through parasites or microscopic bugs. Microrobots can disturb the healthy living of a person with controlled actions though

You say, ”They found out recently that if you try to leave a little kid in a graveyard late at night, he’ll freak out. Even if you offer to leave him a gun to protect himself. Why? It’s because on some instinctual level, all humans know it’s just a matter of time until the zombies show up.

Who are “they?” Where is this evidence? Which scientists are offering guns to children in a graveyard, and who is funding these “experiments?”

How could toxoplasma gondii possibly program humans to be eaten by cats? It would take a completely different organism with a completely different reproductive cycle to have this effect on a human.

Also, the child will freak out in a cemetery, not because they are scared of the undead (unless they have been exposed to such nonsense in the past), but because being in a cemetery reminds a person of their own mortality. Once you come to terms with your mortality, and you realise that there is no hope of further life for a dead person, a cemetery is no longer scary.

Oh, and lurve for @Fyrius.

Oh, yeah. I forgot all about that part.
I addition to ^ their good points, I’m pretty sure little kids would be just as scared if left in a kindergarten alone at night if they’d grow up hearing stories about ghosts and zombies and other scary stuff being associated with that place. Or in a theme park, or wherever. Cemeteries are spooky because everybody always says they’re spooky.

Should we have a Zombie Apocalypse we are protected by the greatest Zombie killer of them all: Keira Knightley.
This idea came from my looking at the book Pride and Prejudice and Zombies.
Before reading the book, I thought it would be a good idea to watch the original version. Keira Knightley did a version some years back, and I began to think about her interaction with Zombies. If beauty were brains, she would be Einstein, but if brains were beauty, well, she’d be Einstein.
Since she lacks the very thing Zombies crave, she could easily move amongst them, and destroy them.

I did a Web search on toxoplasmosa gondii and found this link The article mentions that infected rats gravitate toward cat hangouts, but it does not say anything about turning into zombies, just that the rats are drawn to novelty and open spaces.

@brownlemur Good luck getting that study through the ethics board…

@rhodes54 has exposed this as a plagiarized article from Cracked.

@Dimitris If you have nothing original to contribute please go sit in a graveyard cross legged at midnight in -40 degree temperatures.

I have done this a million times. I am not a small kid you know

@Dr_Lawrence
Are you serious? Plagiarism?

This is the internet, mate. If you still assume everything you read is the original work of the person who posted it, you must be new here. People repost stuff all the time. Often without giving the source. You can usually tell what’s original and what’s copy-pasted.
In this case I doubt @dimitris wanted to make anyone believe this was his own writing. If he did, he did a pretty poor job at it. You can tell this was written like a list article, and that it’s incomplete.

So lighten up.

no mate i just paste it here because I found the contect of the article interesting.. I wanted to know what you think
