We all know what zombies are, from all kinds of movies and shows that try to show what a zombie really looks like and what a zombie apocalypse looks like. Have you ever wondered what a zombie outbreak might actually look like? Research shows that zombies may exist or be created because viruses, bacterial infections, fungi, and many other things show symptoms of possible zombie-like behavior. Humans can be infected by fungi. Mushrooms exist in most of the world's forests. Mushrooms, trees and other plants have a symbiotic relationship by exchanging nutrients. Studies show that chemical signals can be transmitted from one plant to another through fungi. This means that fungal filaments could serve both vascular and neural functions within a corpse. A fungus transports nutrients to muscles in the absence of respiration. The fungi grow inside the brain, where it interfaces with the medulla and cerebellum. Mushrooms release chemicals that activate basic responses within these areas of the brain. A fungus is capable of converting chemical signals that can be transmitted by fungi that extend throughout much of the body. The signal method is slow and imperfect, which results in uncoordinated movements of the zombies. The fungus needs to metabolize the flesh, and the zombies appear to be able to function. A fungus evolves to extract energy and nutrients from flesh in carnivorous plants. The fungi could draw energy from the decay of the host's organic material, meaning it gives an effective shelf life to the zombies. There was a fungal species that used the digestive tract of mammals for travel. The animals ingested the fungus, including the spores. The host's immune system could destroy the fungus. Once the host dies, mutations could lead to the formation of spores. Pigs, which are omnivores, could move to a new host. A Nanobot zombie's final act would mean punching a hole in a healthy victim, allowing the nanobots to enter and set up camp in the new host. Once inside, they can shut down the part of the brain that resists (the cortex) and leave the brainstem intact. In the future, escaping microscopic nanobots will end civilization by flooding the plant with cannibalistic undead.
