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.

Nowak’s paper, however, received major criticisms for erroneously separating inclusive fitness theory from “standard natural selection”. Current theories propose that the evolution of eusociality occurred either due to kin selectionproposed by W. The genetical evolution of social behaviour. This helps explain the abundance of eusocial genera within the order Hymenoptera, including three separate origins within halcitid bees alone. Polygyny in Nasutitermes species: From Wikipedia, the free encyclopedia.

All evidence currently available indicates that obligatory sterile eusocial castes only arose via the association of lifetime monogamous parents and offspring. Seeley 54 Estimated H-index: Each species that practices reproductive altruism is ruled by a queen, the only breeding female who is larger than the rest.


In termites, two additional hypotheses have been proposed. Download PDF Cite this paper. In Organization of insect societies—from genomes to sociocomplexity eds. Sequential polyandry through divorce and re-pairing in a cooperatively breeding bird reduces helper-offspring relatedness. References Publications referenced by this paper. This equality implies that any infinitesimally small benefit of helping at the maternal nest brelative to the cost in personal reproduction c that persists throughout the lifespan of eusodiality cohorts of helpers suffices to establish permanent eusociality, so that group benefits can increase gradually during, but mostly after the transition.

What’s wrong with inclusive fitness? Like in haplodiploidy kin selection, the individuals can propagate their own genes more through the promotion of more siblings, rather evoltion their own offspring.

The Evolution of Social Wasps. Retrieved from ” https: In species where philopatry predominates, and there are few emigrants to the nest, intense inbreeding can occur, as is the case in eusocial species. It uses Hamilton’s kin selection approach in a way that applies to both haploid and diploid organisms.

The monogamy window can be conceptualized as a singularity comparable with the single zygote commitment of gametes in eukaryotes. This paper has been referenced on Twitter 2 times over the past 90 days.

This is when most members of the group give up their own breeding opportunities in order to participate in the reproductive success of other individuals. This could be a precursor, or pre-condition for why eusociality evolved in termites. Philopatry is when individuals remain living in their eusociaoity.
