Detailed explanation-1: -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-2: -"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-3: -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-4: -One of the easiest examples (survival of the fittest examples) is the wooly mammoths. Once the fittest (both physically and reproductively) among all the other biological beings on the Earth, the wooly mammoths vanished from the face of the planet Earth some 1000 years after their evolution.
