The role of ancient developmental genes in trait diversification. Males of
the genus Rheumatobates are known to have highly modified appendages that
aid in the grasping of resistant females. The transition from the ancestral
to the derived states occurs multiple times and in different ways, leading
to a diversity of morphological outcomes (presence and location of
antagonistic hooks and spines etc). The remarkable diversity in these
antagonistic traits may be driven by two processes: a direct response to
differences in female resistance to mating, and/or spatio-temporal variation
in the expression of developmental genes, where a variety of outcomes are
similarly effective. We have recently uncovered the role of an ancient
developmental gene, dll, in controlling the sexually antagonistic
modification of male grasping antennae in Rheumatobates rylei. To determine
the relative importance of these two alternative processes in generating
sexual diversity, we are combining behavioural studies of antennal function
with studies examining the role of dll in the diversification of these
structures, in Rhematobates spp. that span the range of modified antennae.
