We’ve already discussed the possibility that an undead virus may be lurking dormant (see: Zombie Endospores From Hell). Now a recent article from Science Magazine proves that at least one species of complex animal has the ability to literally turn into dust.
Researchers at Cornell University found that the aquatic Bdelloid Rotifer escapes mortal danger by transforming into dried particles and floating off into thin air.
“Bdelloids can rid themselves of a deadly fungal parasite through complete desiccation and disperse by wind to establish new populations in its absence.”
The Rotifers remain in this passive state until they happen to fall into a habitable body of water that is free of any predators, then they suddenly and mysteriously reanimate.
If the walking dead are able to mimic this newly discovered process, their disappearance and reappearance throughout history would be explained. Zombies that can’t find food, or are set on fire, or even shot in the head, could quickly deteriorate to dust and simply drift away. Once external conditions were right, they would then reappear to continue their morbid destruction.
So cross your fingers that the undead have absolutely nothing in common with Bdelloid Rotifers.
