Is luck important in the lives of animals? This project aims to ascertain how much variation in male mating success is attributable to male quality, traits or resources and how much is attributable to luck. Mating is the most important evolutionary process. Male mating success should be highly predictable: males with the best genes, most preferred displays or highest quality resources should attract females. Male mating success is, however, surprisingly difficult to predict and we currently write off up to 90 per cent of the variance as noise. This project aims to quantify the relative importance of deterministic and stochastic sources of variation in male mating success. Ignored variance may be an untapped opportunity to understand selection.

运气在动物的生活中重要吗？该项目旨在确定男性交配成功的差异有多少可归因于男性的质量，特征或资源，以及有多少可归因于运气。交配是最重要的进化过程。雄性交配的成功应该是高度可预测的：拥有最好基因的雄性，最喜欢的展示或最高质量的资源应该吸引雌性。然而，雄性交配的成功率令人惊讶地难以预测，我们目前将高达90%的方差视为噪音。该项目旨在量化男性交配成功的确定性和随机性变异源的相对重要性。被忽略的变异可能是理解选择的一个尚未开发的机会。
