(Things that don't matter but are interesting)
You see lots of movies and books about zombies. They have all sorts of scientific explanations in these movies and books about how the zombies came to be. What makes them animated, why they do what they do, how it spreads, etc. There's one thing they never explain, and I think it's because they can't.
Why don't the zombies eat each other?
In every movie, a living person can't blend in at all. I've even read a book where they tried to make themselves look dead and walk around slowly, and still got found.
Zombies can spot the living from a distance, and walk as a hording team to go get them and consume their flesh/brains/whatever. They never attack each other. In fact, in most cases, they seem to utterly disregard each other, falling over other zombies as they claw their way towards the living.
Let's look at the brain-eating side of it. Do they only want to eat functional brains? Zombies have functional brains. They can walk and maintain somewhat of a sense of balance. They don't crash into walls. They try for the doors and windows if you lock them out. They know to head towards the living. They have the mind to stand up when knocked down, or to crawl on their hands if their legs stop working. Sounds like some gears are turning, so why not eat THAT brain?
Or just the flesh instance. Why not eat zombie flesh? It's the same stuff as the living, except mildly decayed and cold. Do the zombies prefer fresh meat? Have they developed a sophisticated taste for meat that's still within the expiration date and can detect it? If so, how can they detect it? Infrared? Does undead status provide you with heat sensors that can operate at a distance? What about pheromone detectors?
It seems strange that a living person cannot determine such things. In fact, a living person may even have to check for a pulse to make sure someone is dead. The zombies, however, do not. They can spot a living person at a hundred yards or more, and discern them from an undead.
HOW??
Another aspect is in movies like "28 Days Later". They are technically zombies, but overwhelmed by anger and instinct. Thus, they can run and and never stop trying to kill. Yet, the same thing happens. Maybe I don't remember the movie entirely, but if I recall, two raging zombies will fight side by side against a living person, tripping over eachother to do the most damage. Why do they not rage on each other?
If I ever wrote a story about zombies, it'd be boring as hell, and less than one page.
"There was a breakout of zombies in New York City. The National Guard closed all highways leading out and provided air and satellite surveillance for unguarded offbeat routes out of the city. The zombies eventually ate each other and we slowly reconstituted the city after shooting the remainders. The End"
Just random stuff. LOL
