Figure 6.

Evolution of multiple preferences for naturally selected male traits. This figure shows the parameter space, in terms of costs of competition (γ) and strength of female preference (α), where a single preference for a naturally selected trait fixes (gray), both preferences fix (white), and both preferences are lost (black, on the far left along the y-axis). The top figure displays results for successive preference introduction, the bottom shows simultaneous preference introduction. Natural selection on traits counterbalances direct selection against preferences due to competition, allowing at least a single preference to fix under most parameter combinations.
