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.

Hunt 22 Estimated H-index: The evolution of social behavior. This insight led to inclusive fitness and kin selection becoming important theories during the 20th century to help explain eusociality.


Relatedness and the fraternal major transitions. FisherCharlie K.

This ‘true sociality’ in animals, in which sterile individuals work to further the reproductive success of others, is found in termitesambrosia beetlesgall-dwelling aphidsthripsmarine sponge-dwelling shrimp Synalpheus regalisnaked mole-rats Heterocephalus glaberand the insect order Hymenoptera which includes bees, wasps, and ants.

The remainder of the society is composed of a few breeding males, sterile male and female workers, and the young. Sequential polyandry through divorce and re-pairing in a cooperatively breeding bird reduces helper-offspring relatedness. This paper has been referenced on Twitter 2 times over the past 90 days. OldroydMadeleine BeekmanFrancis L. Mmonogamy selection follows Hamilton’s Rulewhich suggests that if the benefit of a behavior to a recipient, taking into account the genetic relatedness of the recipient to the altruist, outweighs the 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. Eusociality can be characterized by four main criteria: The monogamy window can be conceptualized as a singularity comparable with the single zygote commitment of gametes in eukaryotes.

Female Choice in Social Insects. Download PDF Cite this paper. Frequent colony fusions provide opportunities for helpers to become reproductives in the termite Zootermopsis nevadensis Kenneth J. Evolution of paternal care in diploid and haplodiploid populations. Leighton 4 Estimated H-index: These requirements make it a necessity to have high social order for the survival of the group.

Altricial offspring require large amounts of parental care to reach maturity ; 2. Views Read Edit Snd history. This could wvolution a precursor, or pre-condition for why eusociality evolved in termites. Hamilton proposed that eusociality arose in social Hymenoptera by kin selection because of their interesting genetic sex determination trait of haplodiploidy.

Focusing on lifetime monogamy as a universal precondition for the evolution monotamy obligate eusociality simplifies the theory and may help to resolve controversies about levels of selection and targets of adaptation.

The Life of a Dead Ant: Promiscuity and the evolutionary transition to complex societies nature [IF: The first is the Chromosomal Linkage Hypothesis, where much of the termite genome is sex-linked. The increase of colony size in ants, bees, wasps and termites is thus analogous to the evolution of multicellularity.


The eusocial genus Apisthe honeybees, ane the highest recombination rate in higher eukaryotes. Sterile workers of many eusocial species are not actually physiologically sterile. Diversity of entomopathogenic fungi near leaf-cutting ant ligetime in a neotropical forest, evolutionn particular reference to Metarhizium anisopliae var.

In the next paragraph of his book, Darwin describes a solution. Thorne Behavioral Ecology and Sociobiology The genome structure of the order Hymenoptera has been found to have the highest recombination rates of any other groups in Animalia. Philopatry is when individuals remain living in their birthplace.

This paper has highly influenced 15 other papers. The monogamy hypothesis, formulated by Jacobus Boomsma inis currently the leading hypothesis concerning the initial evolution of eusociality in the Hymenoptera.

In naked mole rats, this behavioral dominance occurs in the form of the queen facing the worker head-to-head, and shoving it throughout the tunnels of the naked mole rats’ burrow for quite a distance. Cited 55 Source Add To Collection. HowardPhilip M.
