Summary

Mimicry is a microcosm for evolutionary theory, involving the evolution of polymorphism, transitions between adaptive peaks, origins of biodiversity, and community patterns. The classical view of mimicry and frequency-dependent selection is being challenged, with new ideas emerging on the evolution of Batesian and Müllerian mimicry. Batesian mimicry, where edible prey evolve to resemble unpalatable models, is thought to lead to polymorphism, but this is relatively rare, possibly due to the need for a specific genetic architecture. The coevolutionary chase between models and mimics may not drive mimicry diversification, as the mimic's evolutionary rate is likely higher than the model's, and the model's purifying selection disfavors rare variants.
