The experiment proved that they are not home by smell, but by the way of visual recognition. Ants from the backtrack by the vision, but this vision is very narrow, vision alone is not enough, the ants also have a very strong memory. This impression of memory can be retained even longer the next day. This memory is very loyal, because it guides the team through the various uneven ground, walking the same road in front of a day.
