The species' name refers to the way the little creatures dash about, frequently changing direction with apparently aimless abandon.
But the new findings suggest that the level of aimlessness in these ants' behaviour is in fact very finely tuned.
He said the ants seem to have just the right amount of erratic individualism. About 90% of the time, they will "go with the flow" and pull in the same direction as everybody else; the other 10% of the time they live up to their name.
That means that on the whole, each ant transport team works together and avoids a fruitless tug-of-war. But crucially, their erratic streak leaves a degree of instability - and this allows a single ant with new information to join in and change the directio成立公司
