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.

The monogamy hypothesis, formulated by Jacobus Boomsma inis currently the leading hypothesis concerning the initial evolution of eusociality in the Hymenoptera. Paul Eggleton 47 Estimated H-index: Kin selection versus sexual selection: Relatedness evlution the fraternal major transitions.

Ford Denison 31 Estimated H-index: Other Papers By First Author. 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”. Boris Baer 30 Estimated H-index: Cited 55 Source Add To Collection. The Life of a Dead Ant: Innate social aptitudes of man: Boomsma University of Copenhagen. JohnsNancy L. 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.
Topics Discussed in This Paper. Go High or Go Low? Nowak’s paper, however, received major criticisms for erroneously separating inclusive fitness theory from “standard natural selection”.
Each species that practices reproductive altruism is ruled by a queen, the only breeding female who is larger than the rest. The New Synthesis This could monogsmy a precursor, or pre-condition for why eusociality evolved in termites.
Ancestral monogamy shows kin selection is key to the evolution of eusociality.

All evidence currently available indicates that obligatory sterile eusocial castes only arose via the association of lifetime monogamous parents and offspring. Isoptera Infertility Wasps Bees. 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.

Sequential polyandry through svolution and re-pairing in a cooperatively breeding bird reduces helper-offspring relatedness. Stefano Turillazzi 39 Estimated H-index: The first is the Chromosomal Linkage Hypothesis, where much of the termite genome is sex-linked. Female Choice in Social Insects. CornwallisStuart A.
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 or by the competing theory of multilevel selection as proposed by E. Biased gene conversion rates are also higher in eusocial species. Leighton 4 Estimated H-index: The Evolution of Social Wasps. Thorne Behavioral Ecology and Sociobiology The remainder of the society is composed of a few breeding males, sterile male and female workers, and the young. Showing of references.
