Evolution is the ability of an organism to transcend, to go beyond its current state and to evolve to a more advanced state of existence. When a behavior ceases to be effective and produces results that are not advantages to the species, then the species must make adaptations or risk extinction.

An adaptation is not observed,is not recorded, is not noted as such, but yet it still occurs.

ad·ap·ta·tion: in biology, a change in structure, function or form that produces better adjustment of an animal or plant to its
environment.
