Since Darwin, evolutionary biologists envisaged various hypotheses to explain the advantages for males to exhibit exaggerated secondary sexual traits, also known as ornaments. One of these hypotheses proposes that male ornaments may signal to the females the benefits they can get by mating, and that female preference for ornamented males is one of the main selecting forces explaining the evolution of secondary sexual traits. The evolutionary scenario becomes more complex if we consider that in many species males bear multiple ornaments. Why multiple ornaments should evolve? Why and how do females base their choice among different male traits? Different ornaments could signal different aspects of male quality (=benefits). For example, indivi...
