Humankind has been familiar to zombie apocalypse scenarios for decades and probably centuries, but has neglected the actual possibility of one happening.

These take over their hosts’ bodies, and get them to commit actions unlikely for the species affected and use them as servants. Is it possible for these parasites and fungi to evolve and start affecting humans? One of the parasites responsible for action controlling a certain type of snails is the flatworm Leucochloridium Paradoxum. It enters the snail, as the snail eats a bird dropping.

Slowly, a fungus grows out from the ant’s head. When it grows completely, the fungus releases spores, meant to infect entire colonies.
