The Complexity of Social Complexity: A Quantitative Multidimensional Approach for Studies of Social Organization

It is proposed that measuring the complexity of individual social traits switches focus from semantic discussions and offers several directions for progress, and key social complexity traits can be combined into multidimensional lineage-specific quantitative indices, enabling fine-scale comparison across species that are currently bundled within the same level of social complexity.

Life History and the Transitions to Eusociality in the Hymenoptera

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.

Ecological Drivers of Non-kin Cooperation in the Hymenoptera

The diversity and organization of non-kin sociality across the Hymenoptera is reviewed, particularly among the communal bees and polygynous ants and wasps, with a particular focus on ecological factors.

Phenological and social characterization of three Lasioglossum (Dialictus) species inferred from long-term trapping collections

Detailed social and phenological data collected from nesting aggregations exist for relatively few sweat bee species because nesting aggregations are rarely found in large numbers, even when local

An animal society based on kin competition, not kin cooperation

The first known example of an animal society based on avoidance of kin competition rather than on promotion of kin cooperation is described, leading to the first evidence that kin competition can promote the evolution of societies based on non-kin cooperation.



Comparative methods offer powerful insights into social evolution in bees

The extensive behavioral variation found within the bees is discussed and how the comparative method has improved the understanding of social evolution is highlighted.

Colony Size Evolution and the Origin of Eusociality in Corbiculate Bees (Hymenoptera: Apinae)

The study of this trait improves the understanding of the evolutionary transition from simple to complex societies, and highlights the importance of explicit probabilistic models to test the evolution of other important characters involved in the origin of eusociality.

The impact of molecular data on our understanding of bee phylogeny and evolution.

An overview of significant discoveries in bee phylogeny based primarily on the application of molecular data is presented and how the new phylogenetic insights have altered the understanding of bee biology is described.

Social evolution and casteless societies: needs for new terminology and a new evolutionary focus

It is argued that current terminologies and methods for dealing with non-hierarchical societies are not well suited for such comparative approaches to social evolution and proposed solutions are a re-sampling method to assess investment asymmetries and the introduction of the term “casteless” to encompass forms of social organization.

Phylogenomics Controlling for Base Compositional Bias Reveals a Single Origin of Eusociality in Corbiculate Bees.

These phylogenetic relationships strongly suggest a single origin of eusociality in the corbiculate bees, with no reversal to solitary living in this group.

The evolution of social behavior and nest architecture in sweat bees of the subgenus Evylaeus (Hymenoptera : Halictidae): a phylogenetic approach

The phylogeny suggests that close relatives of L. (E.) fulvicorne and also most of the major species groups of Evylaeus which have not received any field study should be investigated both phylogenetically and behaviorally for a full evaluation of behavioral evolution inEvylaeus.

A single origin of large colony size in allodapine bees suggests a threshold event among 50 million years of evolutionary tinkering

Evolutionary origins of highly eusocial organization involving morphological castes have been very rare, yet these origins have often led to enormous diversification and ecological success. This

The Antiquity and Evolutionary History of Social Behavior in Bees

It is revealed that eusociality first evolved at least 87 Mya (78 to 95 Mya) in the corbiculates, much earlier than in other groups of bees with less complex social behavior.

The evolution of eusociality in allodapine bees: workers began by waiting

In the bee tribe Allodapini, the earliest societies did not entail a foraging worker caste, but instead comprised females sharing a nest with supersedure of dominance, represented a shift towards assured fitness gains by subordinates, mediated by the dual constraints of social hierarchies and environmental harshness.

A Mid-Cretaceous Origin of Sociality in Xylocopine Bees with Only Two Origins of True Worker Castes Indicates Severe Barriers to Eusociality

The results indicate extremely high barriers to the evolution of eusociality, which is likely to have required very unusual life-history and ecological circumstances, rather than the amount of time that selection can operate on more simple forms of sociality.
