Müllerian mimicry is a form of biological mimicry where two or more unpalatable or harmful species evolve to resemble each other. This resemblance helps reinforce the avoidance behavior of predators, as they learn to associate the similar appearance with a negative experience, such as a bad taste or toxicity.
By sharing warning signals, these species benefit from mutual protection. For example, if a predator learns to avoid one toxic butterfly, it will likely avoid other butterflies that look similar. This strategy enhances the survival of all species involved, making it an effective evolutionary adaptation.
