Unicolonial ant populations are the most extensive cooperative units known in nature,
forming networks of interconnected nests extending sometimes hundreds of kilometers …

To counter recent claims that sociobiology is in disarray or requires reformulation, I discuss
the semantics, theory, and data that underlie the field. A historical perspective is used to …

Reciprocity is often invoked to explain cooperation. Reciprocity is cognitively demanding,
and both direct and indirect reciprocity require that individuals store information about the …

Inbreeding frequently has a costly impact on fitness, thus selection has favoured the
evolution of kin recognition and inbreeding avoidance behaviour in many species. As …

Cooperation is subject to cheating strategies that exploit the benefits of cooperation without
paying the fair costs, and it has been a major goal of evolutionary biology to explain the …

In recent years much progress has been made towards understanding the selective forces
involved in the evolution of social behaviour including conflicts over reproduction among …

Natural selection may favor two very different types of social behaviors that have costs in
vital rates (fecundity and/or survival) to the actor: helping behaviors, which increase the vital …

A compelling agent-based computer simulation suggests that ethnocentrism, often thought
to rely on complex social cognition and learning, may have arisen through biological …

Background Fourmidable is an infrastructure to curate and share the emerging genetic,
molecular, and functional genomic data and protocols for ants. Description The Fourmidable …

The Gp-9 gene in fire ants represents an important model system for studying the evolution
of social organization in insects as well as a rich source of information relevant to other …
