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.

Queller Philosophical transactions of the Royal Society…. If the trait of sterility can be carried by some individuals without expression, and those individuals that do express sterility help reproductive relatives, the sterile trait can persist and evolve. RatnieksKevin R. All evidence currently available indicates that obligatory sterile eusocial castes only arose via the association of lifetime monogamous evolytion and offspring.

Evolution of eusociality

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: Raghavendra Gadagkar 27 Estimated H-index: Cited Source Add To Collection.


The ,onogamy window can be conceptualized as a singularity comparable with the single zygote commitment of gametes in eukaryotes. Go High or Go Low?

Showing of extracted citations. Eusocuality evidence currently available indicates that obligatory sterile eusocial castes only arose via the association of lifetime monogamous parents and offspring.

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.

Lifetime monogamy and the evolution of eusociality.

Jane Brockmann 1 Estimated H-index: Low reproductive success rates of solitary pairs that attempt to reproduce. West Current Biology Altricial offspring require large amounts of parental care to reach maturity ; 2. Genetic constraints may have influenced the evolution of eusociality. Lifetime monogamy and the evolution of eusociality. The increase of colony size in ants, bees, wasps and termites is thus analogous to the lifwtime of multicellularity.

The eusocial genus Apisthe honeybees, have the highest recombination rate in higher eukaryotes. Ford Denison 31 Estimated H-index: FosterTom Wenseleers Annual review of entomology Analysis has shown that in Hymenoptera, the ancestral female was monogamous in each of the eight independent cases where eusociality evolved.

Cooperative breeding in wasps eisociality vertebrates: Journal of Theoretical Biology.

Like in haplodiploidy kin selection, evloution individuals can propagate their own genes more through the promotion of more siblings, rather than their own offspring. They depend on interactions with other termites for their gut to be recolonized, thus forcing them to become social.


Sequential polyandry through divorce and re-pairing in a cooperatively breeding bird reduces helper-offspring relatedness. Frequent colony fusions provide opportunities for helpers to become reproductives in the termite Zootermopsis nevadensis Kenneth J. The evolution of social behavior.
