Answer:
The creation and presence of variations is
directionless in regard that they occur randomly and spontaneously. The
variations which are helpful in the adaptations of an organism towards its
surroundings would be passed on to next generations. Natural selection is the
most critical evolutionary process, which can be considered directional as it
leads to only one path that is selection and perpetuation of better adapted individuals.
Natural selection leads to survival of the fittest and disappearance of all
those organisms which do not all fit in the prevailing environmental
conditions.
