This may result in an adaptation due to their being either a positive or negative mutation within the species. i.e a fish is born with night-vision on a random occasion; this fish has a better chance of breeding with another and eventually affects the entire species. The fish move to larger bodies of water where they can hunt safely at night rather than in daylight. This can result in an entirely new night vision bred fish, where they will most certainly push other species out of the metaphorical fish pond.
Natural Selection: survival of the fittest
The primary driving force behind evolution is the environmental pressure, which encourages or discourages certain physical or behavioural adaptations to best fit the environment.
Mutation, isolation and natural selection. Google allopatric speciation.
Adaptation is the result of natural selection.
Species or individuals capable of adaptation live to reproduce. The ones incapable of adapting, do not propagate their genes.

Within a species or multiple species, those with variations that allow them to store water longer or live without it longer will survive more easily. Then, they will reproduce while the less water efficient of their species die out. This is natural selection.

Adaptation is the result of natural selection.
Natural selection is the type of selection that can result in a branching evolutionary tree if it goes on long enough. This is because organisms may eventually evolve into a distinct species.
Genetic polymorphism occurs as a result of natural selection. It represents an equilibrium between members of the same species, and makes use of balancing selection for conservation.
No, adaptations usually do not result in any genotypical change in a species.
