Evolutionary genetics: Mobile DNAs as sources of adaptive change?
Mobile DNAs are potent sources of mutation in wild populations, but seem only rarely to have been used in adaptive evolution. A new study has revealed a mobile DNA insertion in Drosophila simulans that is associated with an apparent selective sweep and an elevation in expression level of an adjacent gene which creates insecticide resistance.
