The Fascinating World of Ant Colonies

Look down at a sidewalk crack, and you might see an ant—a single individual. But that ant is part of a superorganism, a colony that functions as a single entity. Ants communicate using pheromones, leaving chemical trails to food sources that others can follow. They have specialized roles: foragers, nurses who tend to the brood, soldiers who defend the nest, and the queen who lays eggs. Some species even farm fungi or herd aphids for their honeydew. What’s amazing is that no single ant is in charge; it’s a decentralized system of simple interactions that leads to complex, intelligent collective behavior.
