Indigenous cultures, such as the Salishan and the Hopi, have long recognized the similarities between ants and our own species. These creation stories were deeply influenced by what pre-columbus indigenous people experienced and observed in the natural world. The behavior of ants helped them to learn and adapt to their surroundings, as well as to build self-reliant and supportive communities. Scientists have also begun to take note of the similarities between humans and ants through research into ant behavior. Ants have been compared to humans because of their remarkable ability to perform agriculture. The ants of the Attini tribe (subfamily Myrmicinae) can only eat specific fungus that they have learned to grow for themselves within specialized chambers of their colonies (Schultz et al, 2005). Ants are also being researched for their ability to optimize space utilization and traffic flow under extremely crowded conditions (Dussutour et al, 2004). The results of this research may one day lead to better city planning and civil engineering in order to minimize traffic jams.
