Evolution is the scenario which happens at the time of any distress, a group of individuals of certain organisms adapt to the challenges that have raised at the particular environment and change their morphologies.

This might even give rise to new species, whereas if there is no disturbance to the living scenario then there is no need for organisms to evolve and thereby give rise to new species.
