Answer:
As organisms adapt to changing conditions, they evolve in a way to fit their surrounding environment. According to Darwin's <em>survival of the fittest</em> concept, organisms that can adapt to fluctuating conditions are more fitter and hence selected by nature.
Here fitter means reproductive superiority.
Natural selection involve natural causes while artificial selection is by human breeding or human intervention.
The process of domestication is called artificial selection. Like natural selection, artificial selection acts by allowing differential reproductive success to individuals with different genetically determined traits in order to increase the frequency of desirable traits in the population. Natural selection and selective breeding can both cause changes in animals and plants. The difference between the two is that natural selection happens naturally, but selective breeding only occurs when humans intervene.
