We derive a general and exact relationship between fitness fluctuations and response to selection.

We find that during a period of directional selection towards a phenotypic optimum, natural selection favors modifiers which cause an organism to bias its plastic phenotype in the direction opposite to the mean phenotype of the population -- anti-imitation.

Biological evolution provides a creative fount of complex and subtle adaptations, often surprising the scientists who discover them.
