Journal ArticleDOI
Evaluating alternative hypotheses for the early evolution and diversification of ants.
TL;DR: The largest ant molecular phylogenetic data set published to date is generated, containing ≈6 kb of DNA sequence from 162 species representing all 20 ant subfamilies and 10 aculeate outgroup families, and casts strong doubt on the existence of a poneroid clade as currently defined.
Journal ArticleDOI
The evolution of myrmicine ants: phylogeny and biogeography of a hyperdiverse ant clade (Hymenoptera: Formicidae)
TL;DR: In this article, the authors investigated the evolutionary history of a hyperdiverse clade, the ant subfamily Myrmicinae (Hymenoptera: Formicidae), based on analyses of a data matrix comprising 251 species and 11 nuclear gene fragments.
Journal ArticleDOI
Phylogenomic Insights into the Evolution of Stinging Wasps and the Origins of Ants and Bees

TL;DR: There is unequivocal evidence that ants are the sister group to bees+apoid wasps (Apoidea) and that bees are nested within a paraphyletic Crabronidae, and that taxon choice can fundamentally impact tree topology and clade support in phylogenomic inference.
Journal ArticleDOI
The ant subfamily Pseudomyrmecinae (Hymenoptera: Formicidae): phylogeny and evolution of big-eyed arboreal ants
Philip S. Ward,Douglas A. Downie +1 more
TL;DR: Molecular and morphological data support the hypothesis of a sister‐group relationship between Pseudomyrmecinae and Myrmeciinae (84% parsimony bootstrap, combined dataset), which implies a Cretaceous origin of the stem‐group pseudomyrnecines in the southern hemisphere.
