The persistence of extravagant male sexual features like horns and bright colours remains a puzzle. There are many theoretical explanations but empirical tests are still rare. This study, which uses selective breeding, will provide insight into the genetic basis of male sexual attractiveness and dominance. Although focused on an endemic field cricket the potential results have wider implications. They may be applicable to many animals of importance to the community, including livestock, domesticated animals, pests and native wildlife. All these animals are subject to selection pressure created by humans. This study will help us understand how selection on one trait (e.g. weight) may influence the evolution of another (e.g. lifespan).

像角和鲜艳的颜色这样奢侈的男性性特征的持续存在仍然是一个谜。有很多理论上的解释，但实证检验仍然很少。这项采用选择性繁殖的研究将提供对男性吸引力和优势的遗传基础的洞察。虽然重点是地方性板球，但潜在的结果具有更广泛的影响。它们可能适用于许多对社区具有重要意义的动物，包括牲畜、家养动物、害虫和本地野生动物。所有这些动物都受到人类造成的选择压力。这项研究将帮助我们理解对一个性状(如体重)的选择如何影响另一个性状(如寿命)的进化。
