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.

Cooperative brood care is when individuals other than the parents assist in raising the offspring through means such as food gathering and protection.

Ford Denison 31 Estimated H-index: However, many Hymenoptera have a form of lifetime monogamy in which the queen mates with a single male, who then dies before colony founding.

The evolution of social behavior. Cited Source Add To Collection. The evolution of social insect mating systems. The Right Tools for the Job: Lifeitme organisms at first appear to behave in stark contrast with simple interpretations of Darwinian evolution: Frequent colony fusions provide opportunities for helpers to become reproductives in the termite Zootermopsis nevadensis Kenneth J.

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: Renaissance and Enlightenment Transmutation of species Charles Darwin On the Origin of Species History of paleontology Transitional fossil Blending inheritance Licetime inheritance The eclipse of Darwinism Modern lifetimr History of molecular evolution Extended evolutionary synthesis.

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: Are you looking for Kin selection versus sexual selection: Eusociality can be characterized by four main criteria: The remainder of the society is composed of a few breeding males, sterile male eusociqlity female workers, and the young.

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. This helps explain the abundance of eusocial genera within the order Hymenoptera, including three separate origins within halcitid bees alone.

Evolution of reproductive traits in Cataglyphis desert ants: All evidence currently available indicates that obligatory sterile eusocial castes only arose via the association of lifetime monogamous parents and offspring. Inbreeding can mimic and even surpass the effects of haplodiploidy. BreischBarbara L.

Haplodiploidy and Kin selection. With each molt, termites lose the lining of their lifetiime and the subsequent bacteria and protozoa that colonize their guts for cellulose digestion. In species where philopatry predominates, and there are few emigrants to the nest, intense inbreeding can occur, as is the case in eusocial species.

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.

Eusociality evolved repeatedly in different orders of animalsparticularly the Hymenoptera the waspsbeesand ants. Showing of extracted citations.

The monogamy hypothesis, formulated by Jacobus Boomsma inis currently the leading hypothesis concerning the initial evolution of eusociality in the Hymenoptera.

In termites, two additional hypotheses have been proposed.

The first is the Chromosomal Linkage Hypothesis, where much of the termite genome is sex-linked. In The Origin of Specieshe described the existence of lf 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”.

Proceedings of the Royal Society B: Proceedings of the National Academy of Sciences. Like in haplodiploidy kin selection, the individuals can propagate their own genes more through the promotion of more siblings, rather than their own offspring. Citations Publications citing this paper.
