Inclusive fitness theory and eusociality
It is argued that inclusive fitness theory has been of little value in explained the natural world, and that it has led to negligible progress in explaining the evolution of eusociality, but these arguments are based upon a misunderstanding of evolutionary theory and a misrepresentation of the empirical literature.
Light at the end of the tunnel: Integrative taxonom y delimits cryptic species in the Tetramorium caespitum complex (Hymenoptera: Formicidae)
It is highlighted that no single data was sufficient to disentangle the final species boundaries, which underlines the importance of integrating mu ltiple data sources.
The Evolutionary Origin And Elaboration Of Sociality In The Aculeate Hymenoptera: Maternal Effects, Sib‐social Effects, And Heterochrony
A verbal model for the evolutionary origin and elaboration of sib‐social care from maternal care based on the modification of the timing of expression of maternal care behaviors is presented, demonstrating that both maternal effect genes and direct effect zygotic genes are likely involved in the evolution of eusociality.

It is shown that in the adult animal, the converse is true: Genes with low network connectedness (TRGs and tissue-specific conserved genes) underlie novel phenotypes by rapidly changing coding sequence to perform new-specialized functions.

Results indicate that heritable compounds are suitable for establishing a genetic Gestalt for efficient nestmate recognition, but that recognition cues within colonies are insufficiently distinct to allow nepotistic kin discrimination.
Genes associated with ant social behavior show distinct transcriptional and evolutionary patterns
The results indicate that the genetic architecture of social behavior includes both highly connected and conserved components as well as loosely connected and evolutionarily labile components.

The results indicate that the lineages have diverged for both nurse and larval developmental components, that rapid changes in worker body–ovary size allometry may disrupt queen development and that queen–worker dimorphism arises mainly from discrete nurse‐provided nutritional environments, not from a developmental switch that converts variable nutritional environments into discrete phenotypes.
Deconstructing the Superorganism: Social Physiology, Groundplans, and Sociogenomics
The groundplan hypothesis proposes that eusociality arose via simple changes in the regulation of ancestral gene sets affecting reproductive physiology and behavior, and it is argued that this hypothesis is explanatory for the evolution of division of labor but not for the regulatory systems that ensure group-level coordination of action.
Genes with Social Effects are Expected to Harbor More Sequence Variation within and Between Species
It is found that, because genes with indirect social effects on fitness effectively experience weaker selection, they are expected to harbor higher levels of polymorphism relative to genes with direct fitness effects, and a similar pattern of more rapid divergence between populations or species is found.

The ovariole number of foragers was correlated with the sugar concentration of collected nectar, supporting previous studies showing a link between worker physiology and foraging behavior.
