"The Evolution of Eusociality." Nature 466.7310 (2010): 1057-62.
Two forms of life have come to develop eusociality, or, highly-sophisticated, complex societies: humankind and insects (ants, bees, wasps, and termites).
Eusociality, in the rare instances it is achieved, evolves through the process called multi-level selection.
The notion emerged just as sociobiology began promoting the genetics of behavior, and it was all too easy to consider all behavior "selfish." Explanations of cooperation, "altruism," and eusociality were reduced to genes through the concepts of inclusive fitness and kin selection.
But Martin Nowak, a mathematical biologist at Harvard University in Cambridge, Massachusetts, and the lead author of the analysis, said:, "there is no need for inclusive fitness to explain eusociality," reports Nature.
We could continue the trend of ever finer task specialization of our members (Smith, 1838), eventually including specialization in reproductive tasks, following the path to eusociality as exemplified by social insects and the naked mole rats (Heterocephalus glaber).

Examples of specific topics include the influence of intrinsic and extrinsic factors on agonistic behavior in freshwater crayfish, chemical communication and social behavior of the lobster Homarus americanus, ecology and evolution of mating behavior in freshwater amphipods, mating strategies in isopods, sperm demand and allocation in decapod crustaceans, hermaphroditism in caridean shrimps, social behavior of parent-offspring groups in crustaceans, sociobiology of terrestrial isopods, the social breeding system of the Jamaican bromeliad crab, ecology and evolution of eusociality in sponge-dwelling shrimp, and anthropogenic stressors and their effects on the behavior of aquatic crustaceans.
Superorganism is a term used to describe a collection of organisms that exhibit individual division of labor and eusociality. (4)
"For mammals, you don't have to be super related for eusociality to evolve," Faulkes concludes.
Social parasitism is discussed in relation to the evolution of higher grades of sociality (eusociality, cooperative breeding), manipulation success (infectivity), and the evolution of virulence (e.g., aggression, punishment).
Many of the families within this order exhibit eusociality while others are strictly solitary.
Eusociality is relatively rare in nature, and the traditional view has been that a haplodiploid reproductive pattern provides a genetic facilitator.
