The Walking Dead

[Cinjin]

We should make a list of the inherent problems with zombies.

Another would be (from resident evil) "the need to feed"
If only the most basic of functions are reanimated, why wouldn't zombies feed on eachother? In nature, every animal when hungry, scavenger or not, will feed on dead flesh. A zombie with only "basic functions" isn't going to have any idea what flesh is infected and what is not.

... I have others

*raises hand*

How about energy? Going through all these biology classes is teaching me something: to live, our bodies need to produce ATP energy (in fact, a teacher commented that a lazy doctor could list any 'cause of death' as 'lack of ATP'). Our bodies produce ATP from a combination of respiration and digestion of food, yet zombie stories have shown zombies still going, long after they haven't eaten anything for months.

That's yet another inherent problem.


Another:
No stomach or intestines ... no hunger pains. Why would a zombie need to feed an empty hole?

Another:
Vocal chords would decay very very quickly. If a zombie could make a noise it would be minimal and there would certainly be no growling or screaming without air being pushed up our of your lungs ( which the walking dead has made it clear they do not have)

A zombie with only "basic functions" isn't going to have any idea what flesh is infected and what is not.

In some films and series they can smell people, so perhaps they can identify the infected by smell.

A fair point, but one would have to assume that a dead human is not going to have any better smell than he had when he was alive. I can smell red meat. Can you smell cancer? The flu virus? Cause I can't.

Here's another one that even the zombie film makers should keep in mind because it's so obvious.

Zombies popping out of the ground. Utterly ridiculous even assuming that zombies could exist.
Biggest problem: The dead are buried in a reinforced heavy wooden box 6 to 8 feet under ground with 4000 pounds of dirt and a concrete slab stacked on top of them. Even if one or two somehow managed to reanimate, there's no way they could pop up out of the ground.
