Co-option of a coordinate system defined by the EGFr and Dpp pathways in the evolution of a morphological novelty
Publication . Vreede, Barbara MI; Lynch, Jeremy A; Roth, Siegfried; Sucena, Élio
Morphological innovation is an elusive and fascinating concept in evolutionary biology. A novel structure may open up an array of possibilities for adaptation, and thus is fundamental to the evolution of complex multicellular life. We use the respiratory appendages on the dorsal-anterior side of the Drosophila eggshell as a model system for morphological novelty. To study the co-option of genetic pathways in the evolution of this novelty we have compared oogenesis and eggshell patterning in Drosophila melanogaster with Ceratitis capitata, a dipteran whose eggs do not bear dorsal appendages.
