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.

Eusociality appears to be maintained through manipulation of the sterile workers by the queen.

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: Hamilton University College London.

This equality implies that any infinitesimally small benefit of helping at the maternal nest orelative to abd cost in personal reproduction c that persists throughout the lifespan of entire cohorts of helpers suffices to establish permanent eusociality, so that group benefits can increase gradually during, but mostly after the transition. Altricial offspring require large amounts of parental care to reach maturity ; 2.


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 eusocialiity targets of adaptation. Judith Korb 1 Estimated H-index: Origins of cooperative brood care, overlapping generations within a colony of adults, and a division of labor into reproductive and non-reproductive groups.

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

Canalisation Evolutionary developmental biology Inversion Modularity Phenotypic plasticity. Thus, sisters will propagate their own genes more by helping their mothers to raise more sisters, than to leave the nest and raise their own daughters. Lifetime monogamy and the evolution of eusociality.

In species where philopatry predominates, and there are few emigrants to the nest, intense inbreeding can occur, as is the case in eusocial species.

Isoptera Infertility Wasps Bees. The evolution of social insect mating systems. The monogamy window underlines that cooperative breeding and eusociality are different domains of social evolution, characterized by different sectors of parameter space for Hamilton’s rule. Isoptera Search for additional papers on pifetime topic. Haplodiploidy and Kin selection. Yves Roisin 25 Estimated H-index: BreischBarbara L.

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

Inclusive fitness is described as a combination of one’s own reproductive success and the reproductive success of others that share similar genes.

The final evolutiom, reproductive altruism, is the most divergent from other social orders. The genome structure of the order Hymenoptera has been found to have the highest recombination rates of any other groups in Animalia.

An Introduction to Termites: Journal of Evolutionary Biology. In The Origin of Specieshe described the existence of sterile 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”. Kin selection versus sexual selection: The first is the Chromosomal Linkage Hypothesis, where much of the termite genome is sex-linked. Go High or Go Low? Cited 5 Source Add To Collection.

The remainder of the society is composed of a few breeding males, sterile male and female workers, and the young. Ford Denison 31 Estimated H-index: This paper has highly influenced 15 other papers.
