(Ok, here's the beginning to the Thesis. I'll be posting them once a week, every Sunday afternoon until I've completed the Thesis. Keep in mind that this is being written for an internet audience that reads at leisure and this is not the formal draft that I will be submitting.)
Zombies are a fairly new addition to the long list of mythical beasts that plague the human imagination. From the beginning of man, we have feared these creatures of our psyche and have attributed much lore and superstition about them. Ghosts, demons, and monsters all have long stories in our history and even today with all our scientific evolution and understanding, our human nature still promotes the continuation of these lords of lore. A poor lost soul
The Romero Zombie can be described as this. It is the reanimated corpse of a once living individual that has succumbed to the virus which has changed the laws of life. From being a person capable of reason, the person has been transformed into a almost unstoppable force, whoís physiology alone makes them the top of the food chain. Having no need for sleep, air, shelter, or anything that was once a necessity in itís life, it is a creature with plenty of reason to fear. Itís sole motivation is to feed on the living, a instinct that cannot be supplemented in any other way. Once it sees a living human, it will pursue them to the ends of the earth, wanting only to sink itís teeth into our warm, living flesh.
However, it does have one weakness. As we human cannot live without our brain, the undead cannot exist without theirs either. That, is our only way to survive. By destroying the brain in one way or another, we extinguish the threat that has harassed us. The running theory of the Romero Zombie is that, however the cause of itís creation, the Brain must still be intact to give the creature movement. Unfortunately, their brain differs greatly from ours. It doesnít need a flow of oxygen for it to function and most of itís functions have ceased. The ability to reason and form cognitive memories is non-existent and other than the nervous systems control over the body, the pain receptors no longer carry that information to the brain. That means that the body, the most well engineered machine on the planet has no limitations. The body no longer feels pain, fatigue, exhaustion or need to let the body recuperate.
With this knowledge we are lead to only one conclusion. If we are to kill the thing, we gotta blow itís fucking brains out before it eats ours.
