Drupady [299]

According to Darwin's theory of natural selection, struggle for existence  leads to survival of the fittest that means natural selection only tends to favour those organisms that are most fit to survive with the reproductive age in a particular environment and to produce offspring.

Those organisms which fail to adapt to acclimatization are likely to become extinct because they won't be able to survive in the changing environment.

<h3>What is acclimatization?</h3>

Acclimatization is refers to the process where an individual organism adjusts to a change in its environment, allowing it to maintain fitness across a different of environmental conditions.

An example of Darwin theory is if dogs which have a good sense of smell are fit to survive than dogs without a good sense of smell, then all dogs have to evolve a good sense of smell because those with a bad sense of smell die out.
