Sex‐specific evolution of relative leg size in Drosophila prolongata results from changes in the intersegmental coordination of tissue growth

Evolution of relative organ size is the most prolific source of morphological diversity, yet the underlying molecular mechanisms that modify growth control are largely unknown. Models where organ proportions have undergone recent evolutionary changes hold the greatest promise for understanding this process. Uniquely among Drosophila species, Drosophila prolongata displays a dramatic, male-specific increase in the size of its forelegs relative to...
