Abstract: Organisms exist within communities of other interacting species, but knowledge of the mechanisms underlying these relationships, and the evolutionary forces that shape them, is fragmentary. My lab has pioneered the study of rove beetles (Staphylinidae) as a model clade to explore basic questions regarding how organisms interact across species boundaries, and how and why these interactions have emerged during evolution to create the biosphere around us. Most of the >66,000 known rove beetle species are free-living predators, but from this ancestral lifestyle, hundreds of lineages have transformed into remarkable symbiotic organisms, specialized for life as impostors inside the complex societies of ants. The transition from free-living to symbiotic embodies evolution in the extreme, with dramatic changes in social behavior, chemical communication, and life history, which obligately assimilate the beetles into the social fabric of host colonies. The widespread, convergent evolution of this form of symbiosis, combined with the experimental tractability of both free-living and symbiotic rove beetles, provides a unique system to understand the emergence of novel ecological relationships and the evolutionary steps towards highly specialized and irreversibly entrenched symbiotic lifestyles.
