Detailed explanation-1: -Natural selection, also known as “survival of the fittest, ” is the more prolific reproduction of individuals with favorable traits that survive environmental change because of those traits. This leads to evolutionary change, the trait becoming predominant within a population.

Detailed explanation-2: -The survival of the fittest keeps the individuals in any species that can later evolve and form new species. Environment and surrounding conditions change constantly, and once the fittest survive, they need to reproduce even fitter offspring to ensure survival. This is where evolution steps in.

Detailed explanation-3: -"Survival of the fittest” is a popular term that refers to the process of natural selection, a mechanism that drives evolutionary change. Natural selection works by giving individuals who are better adapted to a given set of environmental conditions an advantage over those that are not as well adapted.

Detailed explanation-4: -survival of the fittest, term made famous in the fifth edition (published in 1869) of On the Origin of Species by British naturalist Charles Darwin, which suggested that organisms best adjusted to their environment are the most successful in surviving and reproducing.

Detailed explanation-5: -Natural selection is a mechanism of evolution. Organisms that are more adapted to their environment are more likely to survive and pass on the genes that aided their success. This process causes species to change and diverge over time.
