They might seem simple and insignificant, but like humans, ants have discovered the benefits, and costs of agriculture. In the ant world there are species which farm livestock, protecting them from predators and milking them for rich nectar, and others which cultivate tiny underground fields of fungus, pruning it and using chemicals to prevent disease and pests.
Crops and Livestock
Humans developed farming around 10,000 years ago, but the ants have been at it much longer. In its simplest form, ant farming consists of simply pruning the surrounding forest. Ants of one species found in the Amazonian rainforest have been found to remove unwanted plant species when they appear in its foraging area. Although simple, this ‘weeding’ behaviour can be devastating, with ants clearing huge sections of forest of any species which is not beneficial to them.
