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.

It uses Hamilton’s kin selection approach in a way that applies to both haploid and diploid organisms. Thus, natural selection will favor cooperation in any situation where it is more efficient to raise siblings than offspring, and this could start paving a path towards eusociality.

Evolutionary history of life Index of evolutionary biology articles Introduction Outline of evolution Timeline of evolution. Male workers can still produce sperm, and female workers sometimes wnd eggs, and in some species, become the new queen if the old one dies observed in Hymenoptera, termitesand shrimp.
They depend on interactions with other termites for their gut to be recolonized, thus forcing them to become social. The Evolution of Eusociality.
Lifetime monogamy and the evolution of eusociality. – Semantic Scholar
Judith Korb 1 Estimated H-index: Darwin was on the right track, except sterility is not a characteristic shared among all eusocial animals. The remainder of the society is composed of a few breeding males, sterile male and female workers, and the young. Views Read Edit View history. Download PDF Cite this paper. Female Choice in Social Insects. Kin selection is when individuals help close relatives with their reproduction process, seemingly because relatives will propagate some of the individual’s own genes.
Nowak’s paper, however, received major criticisms for erroneously separating inclusive fitness theory from “standard natural selection”. The Ecology of Social Evolution in Termites. West University of Oxford. The monogamy hypothesis, formulated by Jacobus Boomsma inis currently the leading hypothesis concerning the initial evolution of eusociality in the Hymenoptera.
Origins of cooperative brood care, overlapping generations within a colony of adults, and a division of labor into reproductive and non-reproductive groups. Cited 5 Source Add To Collection. Like in haplodiploidy kin selection, the individuals can propagate their own genes more through the promotion of more siblings, rather than their own offspring.
Journal of Theoretical Biology. Hamilton 1 Estimated H-index: Eusociality can be characterized by four main criteria: Kin selection follows Hamilton’s Rulewhich suggests that if the benefit of a behavior to a recipient, taking into account the genetic relatedness of the recipient to the altruist, outweighs the costs of the behavior to the altruist, then it is in the altruist’s genetic advantage to perform the altruistic behavior.
Lifetime monogamy and the evolution of eusociality.
Stefano Turillazzi 39 Estimated H-index: Advanced eusociality, kin selection and male haploidy. All evidence currently available indicates that obligatory sterile eusocial castes only arose via the association of lifetime monogamous parents and offspring. Uses authors parameter Articles with short description. Ancestral monogamy shows kin selection is key to the evolution of eusociality.
From This Paper Figures, tables, and topics from this paper. Focusing evollution 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.
This is ov most members of the group give up their own breeding opportunities in order to participate in the reproductive success of other individuals. This helps explain the abundance of eusocial genera within the order Hymenoptera, including three separate origins within halcitid bees alone. From Wikipedia, the free encyclopedia. What’s wrong with inclusive fitness?
