Asymmetries are a pervading phenomenon in otherwise bilaterally symmetric organisms
and recent studies have highlighted their potential impact on our understanding of
fundamental evolutionary processes like the evolution of development and the selection for
morphological novelties caused by behavioural changes. One character system that is
particularly promising in this respect is animal genitalia because (1) asymmetries in genitalia
have evolved many times convergently, and (2) the taxonomic literature provides a …
