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.

Extending the modern synthesis with ants: Haplodiploidy and Kin selection.
Termite workers might then bias their cooperative brood care towards their own sex. Download PDF Cite this paper. Explicit use of et evolutuon. The Evolution of Social Wasps. This helps explain the abundance of eusocial genera within the order Hymenoptera, including three separate origins within halcitid bees alone. FosterTom Wenseleers Annual review of entomology Eusociality appears to be maintained through manipulation of the sterile workers by the queen.
Judith Korb 1 Estimated H-index: Thorne Behavioral Ecology and O Wilson The Ants Sociobiology: Cooperative breeding in wasps and vertebrates: Raghavendra Gadagkar 27 Estimated H-index: BreischBarbara L.
Relatedness predicts multiple measures of investment in cooperative nest construction in sociable weavers.
Isoptera Infertility Wasps Bees. With each molt, termites lose the lining of their hindgut and the subsequent bacteria and protozoa that colonize their guts for cellulose digestion.
Wilson 84 Estimated H-index: This hypothesis also mimics the effects of haplodiploidy, but proposes that males would help raise only the queen’s male offspring, while females would only care for the queen’s female offspring.
The increase of colony size in ants, bees, wasps and termites is thus analogous to the evolution of multicellularity. Hunt 22 Estimated H-index: All evidence currently available indicates that obligatory sterile eusocial castes only arose via the association of lifetime monogamous parents and offspring.

From Wikipedia, the lifetimw encyclopedia. This means there is a high cost to dispersing individual may not find another source before it starvesand these resources must be defended for the group to survive. Proceedings of the Royal Society B: The monogamy window can be conceptualized as a singularity comparable with the single zygote commitment of gametes in eukaryotes.
Boomsma University of Copenhagen. All evidence currently available indicates that obligatory sterile eusocial castes only arose via the association of lifetime monogamous parents and offspring.
Lifetime monogamy and the evolution of eusociality.
In Organization of insect societies—from genomes to sociocomplexity eds. The final category, reproductive altruism, is the most divergent from other social orders. Morin 2 Estimated H-index: Kin selection is when individuals help close relatives with their reproduction process, seemingly because relatives will propagate some of the individual’s own genes. Euskciality remainder of the society is composed of a few breeding males, sterile male and female workers, and the young.
In The Origin of Specieshe described the existence of sterile worker castes in the social insects as “the one special difficulty, which at first appeared to me insuperable and actually fatal to my whole theory”. Lifetime monogamy and the evolution of eusociality. Analysis has shown that in Hymenoptera, the ancestral female was monogamous in each of the eight independent cases where eusociality evolved.
Evolution of eusociality
They depend on interactions with other termites for their gut to be recolonized, thus forcing them to become social. Tue Source Add To Collection. West University of Oxford.
