Detailed explanation-1: -According to Darwin’s theory of natural selection, individuals who survive are the ones best adapted for their environment. What is survival due to? Possession of inherited adaptations that maximize fitness.

Detailed explanation-2: -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-3: -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.

Detailed explanation-4: -For Darwin, natural selection is a drawn-out, complex process involving multiple interconnected causes. Natural selection requires variation in a population of organisms. For the process to work, at least some of that variation must be heritable and passed on to organisms’ descendants in some way.

Detailed explanation-5: -The environment creates selective pressure that is one of the driving factors in natural selection. Changes in the environment allow for some organisms to survive better than others within a species.
