Eusociality evolved repeatedly in different orders of animals, particularly the . If a queen is lifetime-strictly monogamous – in other words, she mates with only one individual during her entire life – her progeny will be. Focusing on lifetime monogamy as a universal precondition for the evolution of obligate eusociality simplifies the theory and may help to resolve controversies.

Thus, natural selection will favor cooperation in any situation where it is more efficient to raise mongoamy than offspring, and this could start paving a path towards eusociality.

West University of Oxford. In termites, two additional hypotheses have been proposed.

Cooperative brood care is when individuals other than the parents assist in raising the offspring through means such as food gathering and protection. Although the symbiont hypothesis serves as a pre-condition for termites to evolve into eusocial societies, scientists have found two crucial pre-conditions for the evolution of eusociality across all species.

Hamilton[3] or by the competing theory of multilevel selection as proposed by E. Biased gene conversion rates are also higher in eusocial species.
