Detailed explanation-1: -The concept of “survival of the fittest” in evolution, was coined by Charles Darwin to explain the process of natural selection. The individuals that are the most reproductively successful are the ones that are able to produce the most viable offspring that can survive and reproduce in turn.

Detailed explanation-2: -Survival of the fittest means that organisms that are better adapted to their environment are best suited to survive and successfully reproduce. “Survival of the fittest” is an expression, developed from Darwin’s theory of evolution.

Detailed explanation-3: -Evolutionary biologists use the word fitness to describe how good a particular genotype is at leaving offspring in the next generation relative to other genotypes. So if brown beetles consistently leave more offspring than green beetles because of their color, you’d say that the brown beetles had a higher fitness.

Detailed explanation-4: -Someone not familiar with what natural selection really is might take “fittest” to mean the best physical specimen of the species and that only those in the best shape and best health will survive in nature. That isn’t always the case. Individuals that survive aren’t always the strongest, fastest, or smartest.

Detailed explanation-5: -"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.
