Pond bugs hooked in sex struggle

Male water striders benefit by mating frequently, females by mating infrequently: both have developed traits to give them the upper hand. The researchers modified a gene involved in the development of antennae in male water striders and found that as the antennae became more elaborate, mating success increased. The study is unusual in that it describes a direct linkage between known forces of selection, evolutionary change morphology, and its underlying genetic basis.
