Gazzy is skilled in mimicry and ventriloquism. Automimicry or intraspecific mimicry occurs within a single species. Lecoq wrote on the art and philosophy of mimicry and miming. This may be a case of visual mimicry or perceptual exploitation. There are ways in which autoimmunity caused by molecular mimicry can be avoided. The predator can respond with avoidance, which in turn drives the evolution of mimicry. Many katydids exhibit mimicry and camouflage, commonly with shapes and colors similar to leaves. Jane Doe is a master of disguise and an expert at voice mimicry. This represents the first observation of a Neotropical predator employing this type of mimicry. Batesian mimicry in butterflies and heterostyly in angiosperms are good examples. This discovery is in accord with the principal theory for the evolution of mimicry. Other sources suggest a possible origin in molecular mimicry. These include camouflage, mimicry, toxicity and active defense. Research into an estrogen mimicry that may induce breast cancer is ongoing. Methods include camouflage, nocturnality, subterranean lifestyle and mimicry.
