The researchers were inspired when they made a fascinating chance observation in nature: individual crazy ant workers used their mandibles to pick up and carry away tiny gravel pebbles near groups of workers cooperating to transport large insect prey.

“When we first saw ants clearing small obstacles ahead of the moving load we were in awe. It appeared as if these tiny creatures understand the difficulties that lie ahead and try to help their friends in advance,”

I used to think ants were such nuisances, but now I’m just fascinated by their behavior and how smart they are! Just as long as they stay away from my food lol
