Frequency-dependent Batesian mimicry
David W. Pfennig1, William R. Harcombe1 & Karin S. Pfennig2
Abstract
Predators avoid look-alikes of venomous snakes only when the real thing is around.
Batesian mimicry holds that palatable species look like dangerous species because both are then protected from predation1, 2, 3, 4, 5. But this protection should break down where the dangerous model is absent, when predators would not be under selection to recognize the model or any other species resembling it as dangerous2, 4, 5.
