The reliability of environmental cues shape learning and selection against deleterious alleles in seed beetles | Proceedings of the Royal Society B: Biological Sciences Behavioural plasticity can play a key role in evolution by either facilitating or impeding genetic adaptation. The latter occurs when behaviours mitigate selection pressures that otherwise would targe...

Behavioral plasticity can be a double-edged sword for genetic adaptation.
