Throughout their history army ants developed an evolutionary trait whereby, when separated from the group of other army ants, one ant chooses a random direction and the other ants simply follow the ant in front of them.
Eventually, the army of ants ends up in what is called a 'circular mill,' or a large circle of ants. Some mills can reach up to a 1,200 foot circumference (with a lap time of 2 ½ hours) and will continue until the ants collapse and die or a group accidentally stray from the circle.
