Zombie Origins

There are many ways that a Zombie Apocalypse can begin. There is the classic way of being exposed to too much radiation. There are also myths of ancient idols and artifacts that can change a man into a zombie. Another common way is for it to come from a drug that goes horribly wrong and turns people into flesh eating monsters. The last way--and the most common--is the Virus Origin, where a horrible virus spreads usually originating from from ponds, lakes and rivers in the African region.

If one of these things were to happen, the man made into the monster would typically be called a zombie. But as you can see, through all of these different ways, each way would have a different result. Too much radiation would make your classic zombie while an artifact turned man would make some sort of possessed man. While he would still be called a zombie, he is quite different from your "average every-day zombie". He would be possessed by a god or spirit of some sort and start feeding on the flesh of the living. So, while there are many ways for the zombie apocalypse to start, not every way will have the same result.

(I am basing this Wiki on the Virus Origin, since that is the most common. All of the other Origins are very uncommon.)
