Gene duplication and divergence are overwhelmingly considered to be the primary mechanisms by which cytochrome P450 monooxygenases (P450s) have radiated into a large and diverse gene superfamily. To address how environmental stress drives the fixation and diversification of gene duplications, we have analyzed Cyp12d1 and Cyp12d3, a pair of duplicated genes found in the sequenced Drosophila genomes of the melanogaster group. The paralog Cyp12d3, which is not found in Drosophila melanogaster, is b
