Piwi-interacting RNAs (piRNAs) help defend host genomes against germline transposons. In this issue of Cell, Khurana et al. show how alterations in the piRNA-encoding loci within a single generation allow a naive fly genome to overcome the initially insurmountable challenge imposed by a newly encountered mobile element.
