LIFETIME MONOGAMY AND THE EVOLUTION OF EUSOCIALITY PDF
Request PDF on ResearchGate | Lifetime monogamy and the evolution of eusociality | All evidence currently available indicates that obligatory sterile eusocial. 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.

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.

This could be a precursor, or pre-condition for why eusociality evolved in termites.
Hamilton or by the competing theory of multilevel selection as proposed by E. 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.
This helps explain the abundance of eusocial genera within the order Hymenoptera, including three separate origins within halcitid bees alone. Raghavendra Gadagkar 27 Estimated H-index: In Organization of insect societies—from genomes to sociocomplexity eds.
Eusocial organisms at first appear to behave in stark contrast with simple interpretations of Darwinian evolution: This ‘true sociality’ in animals, in which sterile individuals work to further the reproductive success of others, is found in termitesambrosia beetlesgall-dwelling aphidsthripsmknogamy sponge-dwelling shrimp Synalpheus regalisnaked mole-rats Heterocephalus glabereevolution the insect order Evplution which includes bees, wasps, and ants.
Female Choice in Social Insects. The genome structure of the order Hymenoptera has been found to have the highest recombination rates of any other groups in Animalia. FosterTom Wenseleers Annual review of entomology 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, termiteseusoclality shrimp.
This higher efficiency becomes especially pronounced after group living evolves.

Hughes University of CopenhagenLene Thomsen. Cited 55 Source Add To Collection. Eusociality appears to be maintained through manipulation of the sterile workers by the queen. Nowak’s paper, however, received major criticisms for erroneously separating inclusive fitness theory from “standard natural selection”.
This insight led to inclusive fitness and kin selection becoming important theories during the 20th century to help explain eusociality. This paper has been referenced evoluion Twitter 2 times over the past 90 days. Views Read Edit View history.

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. 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 entire cohorts of helpers suffices to establish permanent eusociality, so that group benefits can increase gradually during, but mostly after the transition.

Conflict resolution in insect societies. Charles Darwin 51 Estimated H-index: Inbreeding can mimic and even surpass the effects of haplodiploidy.
Relatedness predicts multiple measures of investment in cooperative nest construction in sociable weavers. Sterile workers of many eusocial species are not actually physiologically sterile. Hamilton 1 Estimated H-index: The Evolution of Eusociality.
Kin selection follows Hamilton’s Rulewhich suggests that if the benefit of a behavior to a recipient, taking into account the genetic relatedness of eusocialitty recipient to the altruist, outweighs lkfetime costs of the behavior to the altruist, then it is in the altruist’s genetic advantage to perform the altruistic behavior. The symbiont hypothesis in termites is quite different from the others. Cooperative brood care is when individuals other than the parents assist in raising the offspring through means such as food gathering and protection.
