Explanation:
Natural selection is the mechanism by which the species evolve. The species evolve under the influence of the natural pressure due to which the species try to hit and trial method of the adaptive trait. The trait which increases the fitness of a species is passed on to the next generation and the trait becomes established in a population.
This can be observed in the following scenario
1. The hawks predate on the rabbit species with white fur easily as they can be seen from the sky easily.
2. This acts as a pressure on the white rabbits as a result of which the white rabbits to hide themselves mutate and change the colour of the fur from white to brown or tan.
3. The founder effect will eliminate the white fur population from the whole population
4. The population with brown fur will increase with time and the trait will become a permanent trait.
