While creation and presence of variation is directionless, natural selection is directional as it is in the context of adaptation. Comment.

Variations occur randomly and spontaneously in each subsequent generation. These variations may be passed to next generation or may not be. The variation is not passed to next generation when the variation is not supported by the environment. So creation and presence of variation is directionless.

Now when a variation passes the natural selection test it is passed on to next generation. So natural selection is directional as it is in the context of adaptation. Natural selection is called so because it leads to only one path that is selection of better adapted individuals.

Natural selection leads to survival of fittest which survive in the prevailing conditions.
