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.

Eusocial organisms at first appear to behave in stark contrast with simple interpretations of Darwinian evolution: Promiscuity and the evolutionary transition to complex societies nature [IF: This could be a precursor, or pre-condition for why eusociality evolved in termites.

Lifetime monogamy and the evolution of eusociality. – Semantic Scholar

Morin 2 Estimated H-index: Altricial offspring require large amounts of parental care to reach maturity ; 2. However, many Hymenoptera have a form of lifetime monogamy in which the queen mates with a single male, who then dies before colony founding. Evolution of reproductive traits in Cataglyphis desert ants: Like in haplodiploidy kin selection, the individuals can propagate their own genes more through the promotion of omnogamy siblings, rather than their own offspring.


Cited 12 Source Add To Collection. Philopatry is when individuals remain living in their birthplace. The remainder of the society is composed of a few breeding males, sterile male and female workers, and the young.


Hamilton University College London. This seems to be the ancestral state in all Hymenopteran lineages that have evolved eusociality. The Evolution of Eusociality. Termite workers might then bias their cooperative brood care towards their own sex.


The Life of a Dead Ant: FosterTom Wenseleers Annual review of entomology An Introduction to Termites: Charles Darwin considered the evolution of eusociality a major problem for his theory of natural selection.

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

Sterile workers of many eusocial species are not actually physiologically sterile. Hamilton proposed that eusociality arose in social Hymenoptera by kin selection because of their interesting genetic sex determination trait of haplodiploidy. Evolution of paternal care in diploid and haplodiploid populations.

Jane Brockmann 1 Estimated H-index: 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. In species where philopatry predominates, and there are few emigrants to the nest, intense inbreeding can occur, as is the case in eusocial species.


Kin selection is when individuals help close relatives with their reproduction process, seemingly because relatives will propagate some of the individual’s own genes. Charles Darwin 51 Estimated H-index: Diversity of entomopathogenic fungi near leaf-cutting ant nests in a neotropical forest, with particular reference to Metarhizium anisopliae var.

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: 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.

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