Any alteration in the structure or function of an organism by natural selection, that helps it survive in its environment. In the most general sense, adaptation is a feedback process in which external changes in an environment are mirrored by compensatory internal changes in an adaptive system. The actions of the adaptive unit can affect the environment, which, in turn, feeds information back to the adaptive system. Examples include Darwinian biological and alife selection and genetic algorithms, social systems, organic and nanogenic immune systems, natural and artificial neural networks, AIs, neumanns, and more.
