Death spiral Memes

What looks like adorable animal behavior to humans is actually a death spiral for ants. These poor little formicids follow pheromone trails so religiously that if the trail loops, they'll march in circles until they literally drop dead from exhaustion. Evolution gave them an elegant solution for colony navigation but forgot the "infinite loop" error handler. Meanwhile, deer are just prancing around having a grand old time. Nature's coding skills: sometimes brilliant, sometimes fatally flawed.
