Digest: The role of sexual selection in the evolution of aposematism
1Wildlife Ecology and Conservation, Wageningen University, Wageningen, The Netherlands.
Abstract:
Aposematism is an adaptation where individuals evolve conspicuous signals indicating the presence of anti-predator defenses. Maisonneuve and Aubier (2025) explored the role of sexual selection in the evolution of aposematism using a mathematical model and found that some aposematic signals may have originated from sexually selected traits. Their findings suggest that these signals evolved through a combination of mate choice and predation pressure, highlighting the potential interaction between sexual selection and natural selection in shaping the evolution of aposematic signaling traits.
