When a foraging ant returns to the colony from a food source, it emits a chemical signal called a pheromone that marks a trail for other ants to follow. The other ants can follow the pheromone trail, traveling efficiently to the indicated food source. When the food source is plentiful, all of the ants returning to the colony emit the pheromone, reinforcing the signal. When the food source is depleted, the returning ants stop emitting the pheromone, and the trail eventually goes away. Explain the evolutionary origins and benefit of this behavior in ants
