Journal review and gender equality: a critical comment on Budden et al.

into how quantitative trait mapping of a complex behavioral trait can be used as a basis for a detailed candidate gene study. Another recent study [20] shows the promise of using whole-genome gene expression studies in this context, and demonstrates that, rather than structural differences, changes in the expression of Or and Obp genes might be important in the evolution of droso-philid host preference. Taken together, these studies show that the union of ecology, evolutionary genomics, physiology and neurobiology will illuminate how host plant toxins can become co-opted as 'delicious poison,' a question that lies at the heart of insect–plant coevolution and the evolution of specialization.
