The adaptive evolution of male and female aggression in fruit flies and beyond


Displays of intense intrasexual aggression are frequent in many animals. Aggressive behaviour is often extremely variable in form and frequency, both within and among individuals, between the sexes, and across populations and species. What selection pressures give rise to this plasticity and variation? I will present results from studies of fruit flies that demonstrate plasticity in aggression in response to the social and nutritional setting. Despite this plasticity, our work shows that aggressive behaviour evolves rapidly in response to intrasexual competition. I will discuss comparative work on the evolution of sex differences in aggression across vertebrates in response to sexual competition and social structure.
