A first step in understanding the evolution of complex signals is to identify the factors that increase the effectiveness of compound signals with two different elements relative to a single-element signal. Are there, for example, characteristics of novel elements that make a compound call more attractive to prospective mates than a single established element alone? Or is any novel element that increases sensory stimulation per se likely to have this effect?
