Very happy to see our opinion article out in @cp-trendsecolevo.bsky.social today. 🥳 We ask whether sexual signals can influence the evolutionary trajectory of naturally selected adaptations, such as protective colouration, for better or for worse 🧐 1/n

Why do harmful genes persist in populations instead of being removed by natural selection? One answer lies in sexual antagonism: when a genetic variant benefits males but harms females, or vice versa.
