The ants are among the best explorers in the world. Their species and environment may vary but their way to forage for food is similar — when an ant finds a food source, it lays down a pheromone trail on its way back to its nest. Other ants of the colony follow that single path, and they eventually reinforce the pheromone density to strengthen the route.
When I was in grade school, I used to wonder if these ants ever get lost. So, I did an experiment by blocking the ants’ path with a stone. I remembered that the first ant who faced the blockage got disoriented. Then, it randomly moved around the stone as it tried to pick up the pheromone trail again.
