 Obiettivo del progetto (Objective)

'Explaining the origin of complex morphological innovations, in particular conspicuous male ornaments, remains one of the most challenging and exciting questions in the field of evolution. Indeed, conspicuous male-specific traits, either displayed to females during courtship, or used as weapons in battles, likely represent liabilities and should be opposed by natural selection. Darwin proposed that sexual selection is responsible for the evolution of these sexual traits. Since Darwin's time this hypothesis has received considerable theoretical and empirical support. Sexual selection is now perceived as a pervasive force shaping sexual communication systems, acting both on male signaling traits and female preference for these traits. Beyond this generic setup, however, the genetic mechanisms underlying the evolution of male ornaments, and the female preference for these traits, remain largely elusive. The objective of this proposal is to decipher the genetic mechanisms underlying the evolution of a sexual communication system in Drosophila species that have evolved a novel male-specific wing pigmentation pattern displayed to females during courtship. We will examine, on one hand, the emergence, the diversification, and the independent evolution of the male wing pigmentation pattern, and on the other we will explore the nature and the origin of the selective force acting on this signaling trait. We will in particular (i) determine the genetic architecture underlying the formation of the male wing spot in Drosophila biarmipes; (ii) map the genetic sources of male wing spot divergence among species (shape, color, intensity); (iii) identify the genetic and functional bases of the recurrent evolution of the wing spot, and (iv) characterize the nature of the female preference for the male wing spot. By embracing a multi-scale, integrated approach, the ambition of this proposal is to shed a new light on the evolution of sexual communication systems in animals.'
