Protective Eyes on butterfly wings
To survive, butterflies have learned to protect themselves from enemies. In the process of evolution, on their wings appeared images that resemble eyes of predators, scientists believe. Every person, at least once in his life, has seen patterns on butterfly wings resembling the eye. These patterns serve a very useful function — they provide butterflies with protection from birds of prey. First British scientists believed that the patterns on the wings of butterflies scare predators, because such protective eyes on butterfly wings represent a specific combination of colors and shapes deterrent to the predator. However, scientists from the University of Jyvaskyla in Finland do not agree with this.
