| Abstract: | Adaptive mate preferences are generally assumed to be static and open-ended, favouring the most extreme expression of display traits. In contrast to this view, three new studies show that genetic benefits from mate choice can be context-dependent. Thus, there might be short-term fluctuations in selection on mate preferences. The crucial question then is, are plastic mate preferences an optimal evolutionary outcome? |
