Abstract

With perhaps a thousand species present in the endemic fauna, the Hawaiian Drosophilidae represents one of the most striking examples of explosive adaptive radiation known in the animal kingdom. However, there is mounting evidence that it is shifts within the sexual environment that are more important in the speciation process. Classical concepts of sexual selection theory are reviewed and some new ideas regarding the role of sexual selection in the origin of secondary sexual characters are presented. It is suggested that there is a range of mating types in both sexes and that differential selection between the two sexes, i.e. selection for males with superior mating ability and for less discriminant females, results in the maintenance of an optimum behavioural phenotype in the population. It is further suggested that the dynamics of the sexual selection process and the effects of pleiotropy play a significant role in levels of genetic variability in a single interbreeding population.

Résumé

Avec environ mille espèces présentes parmi la faune indigène, les Drosophiles Hawaïennes constituent l'un des exemples les plus frappants de radiation adaptive explosive connus dans tout le royaume animal. Cependant, il y a de plus en plus d'évidences que des changements sur le plan de l'environnement sexuel sont d'une plus grande importance dans le processus de spéciation. Dans la présente étude les concepts classiques de la sélection sexuelle sont ré-examinés et des idées neuves sur le rôle de la sélection sexuelle dans la génération de traits sexuels secondaires sont présentées. On suggère qu'il y a une gamme de types reproducteurs des deux sexes et que la selection différentielle entre les deux sexes—c'est à dire sélection qui favorise les males à puissance supérieure et les femelles les moins discriminantes—garantit le maintien d'un phénotype comportemental optimal dans la population. De plus, il est suggéré ici que la dynamique du processus de sélection sexuelle et les effets de la pléiotropie jouent un rôle important dans la détermination du niveau de variabilité génétique dans une population où les drosophiles reproductrices s'entrecroisent.
