Would zombie insects, zombie bacteria, zombie parasites still do the same thing and have the same control if the partnership was somehow transported and living on another planet?
If they could not do the same thing then would that show they could not access the same universe information? Or would it be purely an environmental issue?
If the host animal, plant or lifeform was not there but other lifeforms were, would they adapt to make zombie slaves of different life forms?
Would human infections and diseases by external parasites such as bacteria, viruses and other animals still target humans, would they still work in the same manner?
