摘要

性选择往往会使性状朝着自然选择不喜欢的方向发展。这两种选择之间的平衡会随着环境的变化而迅速改变。Gallagher 等人（2024 年）报告了蟋蟀种群在引入寄生蝇后发生的这种转变。祖先的雄性形态虽然仍受雌性青睐，但已被寄生虫更难发现的多种新型形态所取代。

Digest: When sexual selection hits the wall of natural selection.

Sexual selection often drives traits in a direction that is disfavored by natural selection. The balance between these two types of selection can shift rapidly in response to environmental changes. Gallagher et al. (2024) report such a shift in the cricket population following the introduction of a parasitoid fly. The ancestral male morph, though still preferred by females, has been supplanted by multiple novel morphs that are more difficult for the parasitoid to detect.
