Every Halloween, we talk about zombies. But what if nature already made them? In this Fright Facts Week episode of Smartest Year Ever, Gordy explores the real-life fungus that controls ants like puppets, forcing them to climb, freeze, and die so it can spread. Known as Ophiocordyceps unilateralis — or the zombie ant fungus — this mind-controlling parasite shows that nature’s horror stories can be even more chilling than fiction.
Gordy breaks down how this fungus invades an ant’s body, grows through its muscles, hijacks its movements, and even makes it clamp down on leaves before sprouting a spore-filled stalk from its head. Scientists have discovered that it doesn’t even need to touch the brain — it’s pure biological manipulation, what Richard Dawkins called an “extended phenotype.”
This episode dives into the evolutionary precision of parasitic fungi, how Cordyceps species target specific insects, and what they reveal about behavioral control in nature. And yes — it even touches on whether something like this could ever infect humans (fans of The Last of Us, listen closely).
Perfect for fans of science, horror, and biology, this one proves that the most terrifying monsters aren’t in movies — they’re in the rainforest.
