Improving our understanding of population fitness could produce important new advances in evolutionary and conservation biology. Sexual selection has been proposed to both help and harm population fitness, but unfortunately these opposing effects have been studied in isolation. This project will develop new theory to resolve confusion over the definition of population fitness and its relationship with sexual selection. It also proposes ambitious experimental evolution and quantitative genetic studies that will empirically measure the net effect of sexual selection on population fitness and extinction. This project aims to catalyse a change in the study of population fitness and address a conspicuous gap in contemporary evolutionary biology.

提高我们对种群适应度的理解可以在进化和保护生物学方面产生重要的新进展。性选择被认为既有助于也会损害种群的适应性，但不幸的是，这些相反的影响被孤立地研究。该项目将发展新的理论，以解决对种群适应度定义及其与性选择关系的困惑。它还提出了雄心勃勃的实验进化和定量遗传研究，将经验性地衡量性选择对种群适应度和灭绝的净效应。该项目旨在催化种群适应性研究的变化，并解决当代进化生物学中的一个明显差距。
