Summary
Whether the changes brought about by sexual selection are,
on the whole, congruent or incongruent with the changes
favored by natural selection is a fundamentally important
question in evolutionary biology. Although a number of
theoretical models have assumed that sexual selection rein-
forces natural selection [1, 2], others assume these forces
are in opposition [35]. Empirical results have been mixed
(see reviews in [1, 68]) and the reasons for the differences
among studies are unclear. Variable outcomes are expected
