The Worker and soldier ants also divide into smaller groups. Each group has a job that complements the others. For example, one worker group extends the nest, and another repairs it. Others grow their own food like farmers, and still others manage small'farms'in which they raise smaller animals. In the same way as humans breed cows and use their milk, ants breed small insects called aphids and'milk'them to obtain a sugary liquid. Some scientists are examining how studying ants can lead to a better understanding of labor issues, social class, and the use of natural resources in human communities. Ants have had millions of years of practice in working together to survive and grow. For a colony to function successfully, ants have to cooperate, and they do so without exception. Researchers hope that gathering information about how ants live together m communities can help people learn to cooperate and compromise with each other. However, others argue that there are fundamental differences between ants and humans that mean human societies are unlikely ever to attain ant-like levels of collaboration. For example, ants in a colony don't compete with each other. When there is a shortage of food in the colony, some worker ants automatically become'feeder' ants and feed others with the food in their stomach, regardless of their usual job. When the food supply is replenished, they become worker ants again. In addition, ants are able to work together without a leader giving them directions. Despite their name, queen ants are not leaders. Instead, ants find out what they need to do from their sense of smell. Research on harvester ants by Deborah Gordon and Michael Greene in 2010 showed that when harvester ants pass each other, they pick up a chemical smell which tells them what the other ant is doing. The number of ants they pass doing a particular job determines what they need to do. It is a form of communication, but unlike human communication It has no content; It Is just based on numbers. If you are working in an office and you receive an email instructing you to do somethi ng, you know what to do because of the content of the email. If humans were like ants, it wouldn't matter what the email said — the important thing would be the number of emails. While ants undoubtedly have a great deal to teach us about organization and the structure of networks, those searching for a greater understanding of human behavior and morals may need to look elsewhere.
