Changing paradigms in insect social evolution: insights from halictine and allodapine bees.
Until the 1980s theories of social insect evolution drew strongly on halictine and allodapine bees. However, that early work suffered from a lack of sound phylogenetic inference and detailedExpand

Evolution of sociality in the allodapine bees: a review of sex allocation, ecology and evolution
Summary: Comparative studies provide one of the most powerful means of assessing the relative roles of selective agents underlying social evolution in insects. Because of the wide variation in socialExpand

Molecular phylogenetics of allodapine bees, with implications for the evolution of sociality and progressive rearing.
Allodapine bees have long been regarded as providing useful material for examining the origins of social behavior. Previous researchers have assumed that sociality arose within the Allodapini andExpand

Molecular phylogenetics of the exoneurine allodapine bees reveal an ancient and puzzling dispersal from Africa to Australia.
Previous phylogenetic studies of the bee tribe Allodapini suggested a puzzling biogeographic problem: one of the key basal divergences involved separation of the southern African and southernExpand
