In the course of evolution all plant species and animals adapted to dwelling environmental conditions. It is possible to refer to adaptation behavior of animals, features of the structure of a body and, of course, coloring. The last treats means of protection from possible predators and it ensures safety of a look in general.
As good security measure from enemies serve different types of coloring of a body. For example, patronizing when pigmentation makes animals a little noticeable against the background of the environment. However, animals are very often painted also in the bright noticeable colors drawing to themselves attention. It is peculiar to the poisonous, burning or stinging insects: to wasps, bees, bugs-naryvnikam, etc. Venomous snakes, inedible caterpillars which the look warn about dangers attacks on them have a bright pattern. Besides, such coloring is usually combined with the display behavior which is frightening off a possible predator. The efficiency of the warning coloring was the reason of emergence in the nature of types imitators. The phenomenon at which the similarity of one view with unrelated, yarkookrashenny other species appears received the name of a mimicry (from Greek - imitative). Its emergence is connected about accumulation of useful mutations under control of natural selection in the conditions of joint dwelling of edible views (simulators) with inedible (models). At what not always about simulators as models use animals: some butterflies in a form, coloring are very similar to a lichen, leaves, caterpillars – on branches, etc. Or here other examples: one species of cockroaches is similar to a ladybug the sizes, in color, distribution of spots, and some flies imitate wasps, edible butterflies – inedible, examples there will be a set.
The mimicry though it is considerable less than in fauna occurs among plants too: some forms of weed Vika which seeds are very similar to lentil seeds, external similarity of a yasnotka white ("a deaf nettle") with a usual two-blast furnace the nettle having the burning hairs. Bodies of some plants during natural selection began to remind on appearance of insects or objects of inanimate nature. For example, flowers of several types of orchids are similar to females of wasps and by that they attract males who pollinate them. And representatives of family of a milkweed family have the tubers similar to stones. It is clear to all that in the nature the imitation is justified as a smaller part of individuals both the look which served as model, and a look imitator is exposed to destruction. But at the same time very important condition always has to be met: the number of simulators is obliged to be less than the number of models, otherwise there will be no advantage of a mimicry.
