LIFETIME MONOGAMY AND THE EVOLUTION OF EUSOCIALITY PDF

Request PDF on ResearchGate | Lifetime monogamy and the evolution of eusociality | All evidence currently available indicates that obligatory sterile eusocial. 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.

Relatedness predicts multiple measures of investment in cooperative nest construction in sociable weavers. Hamilton proposed that eusociality arose in social Hymenoptera by kin selection because of their interesting genetic sex determination trait of haplodiploidy.

Jane Brockmann 1 Estimated H-index: The symbiont hypothesis in termites is quite different from the others. Haplodiploidy and Kin selection. This insight led to inclusive fitness and kin selection becoming important theories during the 20th century to help explain eusociality.

It uses Hamilton’s kin selection approach in a way that applies to both haploid and diploid organisms. From Wikipedia, the free encyclopedia. Wilson 84 Estimated H-index: 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.

With each molt, termites lose the lining of their hindgut and the subsequent bacteria and protozoa that colonize their guts for cellulose digestion.

Warrington 4 Estimated H-index: However, many Hymenoptera te a form of lifetime monogamy in which the queen mates with a single male, who then dies before evoluyion founding. The remainder of the society is composed of a few breeding males, sterile male and female workers, and the young. Colony life history in the bumble bee Bombus terrestris: In many monogamous animals, an individual’s death prompts its partner to look for a new mate, which would affect relatedness and hinder the evolution of eusociality: Lifetime monogamy and the evolution of eusociality.

Male workers can still produce sperm, and female workers sometimes lay eggs, and in some species, become the new queen if the old one dies observed in Hymenoptera, termitesand shrimp. Lifetime monogamy and the evolution of eusociailty. Seeley 54 Estimated H-index: The monogamy hypothesis, formulated by Jacobus Boomsma inis currently the leading hypothesis concerning the initial evolution of eusociality in the Hymenoptera.

Proceedings of the National Academy of Sciences. In species where philopatry predominates, and there are few evollution to the nest, intense inbreeding can occur, as is the case in eusocial species.

Current theories propose that the evolution of eusociality occurred either due to kin selectionproposed by W. All evidence currently available indicates that obligatory sterile eusocial castes only arose via the association of lifetime monogamous parents and offspring.

Kin selection is when individuals help close relatives with their reproduction process, seemingly because relatives will propagate some of the individual’s own genes.
