Stalk-eyed flies therefore provide an ideal model system to study sexual
selection, and much of our research has focused on investigating “good
genes” and direct benefit models of sexual selection. We use both
phenotypic and genetic approaches, combining experimental manipulation,
artificial selection, molecular analyses and fieldwork.
We have also been using a variety of techniques to elucidate the genes
involved in the development of the eye-stalks. We plan to use this information
to work out the molecular pathways and mechanisms involved in the evolution
of these exaggerated sexual ornaments.
