My research interests centre on the evolution of cooperative animal societies. Cooperation is an evolutionary puzzle. While a simple reading of natural selection as ‘survival of the fittest’ predicts that individuals will benefit from selfish, competitive behaviour, cooperation is not only commonplace within nature, but is of profound evolutionary and social significance. I work to reveal the causes of conflict between cooperative partners and the mechanisms that have evolved to resolve these conflicts. My work draws on a variety of biological disciplines, combining observational, biochemical, molecular ecological and genetic methods. This approach provides a powerful technique to reveal the important influences of reproductive success, kinship, inbreeding avoidance and environmental change on the evolution of cooperative animal societies.
