Which of the following is true about natural selection? ​
Anna007 [38]

The options for this question are:

- Requires genetic variation

- Results in descent with modification

- Involves differential reproductive success

- All of the above

Answer:

<u><em>The correct option is d) All of the above</em></u>

Explanation:

The theory of natural selection explains that genetic variations occur in organisms of a species. Those organisms which are better adapted to live in an environment are able to survive and pass on their characteristics to their offsprings, hence descent with modification. Through this phenomenon, evolution takes place with the passage of time. Natural selection favours survival of the fittest. Hence, all of the above statements are true.
