The genomic revolution has stabilized the phylogeny of the Formicidae, but does not explain how ants came to be the way that they are. Here, we present a total-evidence phylogeny of the Formicoidea, introducing a new stem lineage which sheds light on the origin of eusociality. Functional morphology plays a key role in understanding these transitions. We propose a new framework for understanding the earliest evolution of the ants, and for survival into the Cenozoic.
