Analyses on evolutionary relationship between insect wings and crustacean carapaces

In this study, I revealed that three essential genes for insect wing development also play inevitable roles in crustacean carapace development, suggesting that this molecular mechanism existed in the last common ancestor of insects and crustaceans. By detailed comparisons of various marker gene expressions, I suggested that this molecular mechanism for dorsal flat outgrowth was co-opted during arthropod evolution and that crustacean carapaces and insect wings have evolved independently.
