Interspecific variability in Drosophila

Jean David (IGGIPOP ) took part in the work ending with the publication of Nagy, O et al in Current Biology.

In this article, the authors showed that a single mutation contributes both to the loss of sensory organs under the phallus of some drosophila species and to the up sizing of a sex comb on their legs. This is the first report of morphological evolution between species occurring through the change of a single nucleotide.

These results were the basis of  a short article on the website of INSB in CNRS.
