<em>Coevolution</em> is a process in which two individuals reciprocally affect each other's evolution. In this process the interacting species exert selective pressures on each other thus, affecting their evolution. Due to this reciprocal adaption they become so close that the evolution of one species is affected by the other.
B/c each color is refracted differently, each bends at a different angle, resulting in a fanning out and separation of white light into the colors of the spectrum.
