zombie ants, the basis of the show Last Of US
The show got me wondering is Fungi intelligent. How can a non- intelligent life form take control and use a life form with intelligence, even if it is very low. My research came up with:
The zombie ant fungus doesn't give precise step-by-step movement commands like a remote control. Instead, it hijacks the ant’s nervous and muscular systems in a way that makes it behave in a strangely "normal" way—at least until it reaches the climb-and-bite stage.
How It Moves Without Getting Detected:
-
Preserved Locomotion – The fungus doesn’t completely destroy motor functions; it keeps the ant walking in a somewhat natural way to avoid detection.
-
Stealth Mode – The infected ant may avoid erratic movements or unnatural behaviors until the final climb, reducing the chance of nestmates noticing and removing it.
-
Neural Hijacking, Not Brain Control – The fungus mainly affects muscles, not higher brain functions, allowing the ant to navigate obstacles as if it were making its own choices.
-
Environmental Triggers – The fungus seems to time its control mechanisms based on temperature, humidity, and light conditions to guide the ant to an optimal location.
It's a blend of biochemical control and letting the ant’s existing instincts do most of the work.
Infection Timeline (From Spore to Death)
-
Spore Attachment (0–2 Days) – The fungal spores land on an ant, penetrate its exoskeleton, and begin spreading inside.
-
Growth & Manipulation (4–10 Days) – The fungus spreads through the ant’s body, hijacking muscles and subtly altering behavior.
-
The Death March (10–14 Days) – The ant leaves its colony, climbs vegetation, and locks its jaws in place (the "death grip").
-
Death & Fungal Emergence (15–25 Days) – The fungus kills the ant, then a stalk grows out of its head, releasing spores to infect others.
Can Ants Resist the Infection?
Yes, but it depends on several factors:
-
Social Hygiene – Healthy ants recognize infected nestmates and remove or kill them before the fungus can spread.
-
Self-Removal – Some infected ants seem to leave the colony earlier, possibly as an instinctive defense mechanism.
-
Colony Relocation – Some ant colonies have been observed moving away from high-infection zones.
-
Immune Response – If an ant's immune system is strong enough, it might fight off the fungus before it takes hold.
Despite these defenses, Ophiocordyceps is incredibly effective, and infected ants rarely survive once spores take root inside them.
