Close relatedness has long been considered crucial to the evolution of eusociality. [] Key Method We tested this idea with a comparative analysis of female mating frequencies in 267 species of eusocial bees, wasps, and ants. We found that mating with a single male, which maximizes relatedness, is ancestral for all eight independent eusocial lineages that we investigated. Mating with multiple males is always derived. Furthermore, we found that high polyandry (>2 effective mates) occurs only in lineages whose…
Monogamy and high relatedness do not preferentially favor the evolution of cooperation
TLDR
It cannot be concluded that monogamy is a predisposing state for the evolution of helping behavior, but how best to elucidate the differing evolutionary advantages of genetic relatedness versus genetic diversity is questioned.
Eusociality and Cooperation
TLDR
Overall, eusociality evolved when ecological conditions promote stable associations of related individuals that benefit from jointly exploiting and defending common resources.
Relatedness, Conflict, and the Evolution of Eusociality
TLDR
A broad agreement of different models shows that social evolution theory, rather than being in turmoil, is supported by multiple theoretical approaches and suggests that extensive prior work using inclusive fitness, from microbial interactions to human evolution, should be considered robust unless shown otherwise.
Life History and the Transitions to Eusociality in the Hymenoptera

TLDR
In this study, ancestral state reconstruction on recently published phylogenies was used to identify the independent transitions to eusociality in each of the taxonomic families that exhibit eussociality.
The mating biology of termites: a comparative review
Kin structure, ecology and the evolution of social organization in shrimp: a comparative analysis
TLDR
It is shown that eusocial species are more abundant, occupy more sponges and have broader host ranges than non-social sister species, and that these patterns are robust to correction for the generally smaller body sizes of eussocial species.
Convergent Reversion to Single Mating in a Wasp Social Parasite
TLDR
It is shown that the workerless social parasite Dolichovespula arctica, a derived parasite of wasps, has reverted to obligate single mating from a facultatively polyandrous ancestor, mirroring a similar reversion from obligate polyandry to approximate monandry in a social parasite of fungus-farming ants.
The evolution of eusociality
TLDR
It is argued that standard natural selection theory in the context of precise models of population structure represents a simpler and superior approach, allows the evaluation of multiple competing hypotheses, and provides an exact framework for interpreting empirical observations.
No Synergy Needed: Ecological Constraints Favor the Evolution of Eusociality
TLDR
It is shown here that constraints on independent breeding (through nest-site limitation and dispersal mortality) eliminate any need for synergistic efficiency gains: sterile helpers may evolve even if they are relatively inefficient at rearing siblings, reducing their colony’s per-capita productivity.

Advanced eusociality, kin selection and male haploidy
TLDR
It is suggested that sex allocation is deep at the heart of the evolution of hymenopteran advanced eusociality, indicating the interacting roles of population genetics and general biology, and that relatedness is deeply intertwined with ecology so that both are essential.
Pedigree relatedness, not greenbeard genes, explains eusociality
TLDR
It is concluded that both phylogenetic studies and studies of intra-genomic conflict support the importance of pedigree relatedness in the evolution of eusociality.
Recent and simultaneous origins of eusociality in halictid bees
TLDR
Results from relaxed molecular clock dating techniques indicate that the three independent origins of eusociality in halictid bees occurred within a narrow time frame between approximately 20 and 22 Myr ago, suggesting that climate may have had an important role in the evolution and maintenance of eusociality in these bees.
High relatedness and inbreeding at the origin of eusociality in gall-inducing thrips.
TLDR
Results indicate that unusually high relatedness is associated with the origin of eusociality, and they suggest a role for inbreeding in the evolution of bisexual helping.
One Giant Leap: How Insects Achieved Altruism and Colonial Life
TLDR
Several lines of evidence are examined, examined here, suggest that collateral kin selection does not play a significant role in the approach to eusociality in the Hymenoptera and that group selection immediately acts on key emergent traits arising from interactions of the group members.
Ant parasite queens revert to mating singly
TLDR
It is found that although the host queens mate with up to a dozen different males, the social parasite mates only singly, indicating that the costs of polyandry are probably specific to a free-living lifestyle.
Eusociality: origin and consequences.
In this new assessment of the empirical evidence, an alternative to the standard model is proposed: group selection is the strong binding force in eusocial evolution; individual selection, the strong
Multigene phylogeny reveals eusociality evolved twice in vespid wasps
TLDR
A phylogeny of Vespidae based on data from four nuclear gene fragments and representatives from all six extant subfamilies indicates two independent origins of vespid eusociality, once in the clade Polistinae+Vespinae andonce in the Stenogastrinae.
