They depend on interactions monohamy other termites for their gut to be recolonized, thus forcing them to become social. The evolution of social insect mating systems. 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.

If the trait of sterility can be carried by some individuals without expression, and those individuals that do express sterility help reproductive relatives, the sterile trait can persist and evolve.

Focusing on lifetime monogamy as a universal precondition for the evolution of obligate eusociality simplifies the theory and may help to resolve controversies about levels of selection and targets of adaptation. Advanced eusociality, kin selection and male haploidy. However, many Hymenoptera have a form of lifetime monogamy in which the queen mates with a single male, who then dies before colony founding.

Like in haplodiploidy kin selection, the individuals can propagate their own genes more through the promotion of more siblings, rather than their own offspring. Hamilton University College London. This paper has highly influenced 15 other papers.

LIFETIME MONOGAMY AND THE EVOLUTION OF EUSOCIALITY PDF

Abstract All evidence currently available indicates that obligatory sterile eusocial castes only arose via the association of lifetime monogamous parents and offspring. This equality implies that any infinitesimally small benefit of helping at the maternal nest b , relative to the cost in personal reproduction c that persists throughout the lifespan of entire cohorts of helpers suffices to establish permanent eusociality, so that group benefits can increase gradually during, but mostly after the transition. The monogamy window can be conceptualized as a singularity comparable with the single zygote commitment of gametes in eukaryotes. The increase of colony size in ants, bees, wasps and termites is thus analogous to the evolution of multicellularity. Focusing on lifetime monogamy as a universal precondition for the evolution of obligate eusociality simplifies the theory and may help to resolve controversies about levels of selection and targets of adaptation. Darwin , p.

Thus, sisters will propagate their own genes more by helping their mothers to raise more sisters, than to leave the nest and raise their own daughters.
