Referring to a discussion about surviving a zombie apocalypse as 'philosophical' is pretty bold. This is pure fantasy, and I think people know that. Any sane person who thinks about biology for a few minutes should come to a realization that a zombie apocalypse is literally impossible due to necrosis. This discussion is for fun. So of course these things are going to be ignored.This philosophical discussion ignores the fact that zombie infections are magical in nature in basically all media, other than maybe 28 Days Later.
In The Walking Dead they play it up as a disease but you have zombies melted into the ground with nothing left but half of their head and they're still 'alive.' And decapitation stops everything below the neck but somehow the head still tries to bite you, and it never relies on any fuel from a body. That's necromancy at work. In 7 Days to Die you have crawler zombies whose bodies are almost completely destroyed and drained of blood but you can poke them and make them bleed to death. Plus you have burning zombies you can kill with fire. That's necromancy mixed with drugs.
In short, everything you think you know about how the disease could work will go out the window once our dark lords actually rise up and decide to rid the planet of us.
The term 'zombie ant' is quite misleading. The ant, while infected, is not dead. It's not in control of its own actions, but it is definitely not dead, and therefore, not a zombie.Well..... this would be possible for ... fungus. zombie ants can be "heavy" damaged but still able to walk
Of course, we can debate what you define as a zombie, but in general terms, I'm pretty sure mist will agree that it is a reanimated corpse. This is why I think it's funny that people categorize '28 Days Later' as a zombie movie. Even Danny Boyle, the director, doesn't categorize it as a zombie film.
