Eusociality can be seen in a variety of insect families, including the ants (Formicidae). There is no clear understanding on how it evolved but it is well understood that transitions between social phases must happen. Several theories and hypothesis have been presented but none of them completely encapsulate the whole evolution of eusociality. Several studies on ants focus on different aspects of their evolution in the eusocial context and provide good supporting data. Two major models, Alternate Inclusive Fitness Model and Worker Behavior Model, are good blueprints for future research. As more data is collected and studies were done, more light will be shed on the subject.
