LIFE SCIENCE

Detailed explanation-1: -Darwin called this mechanism natural selection. 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.

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: -Survival of the fittest is a simple way of describing how evolution (the process by which gradual genetic change occurs over time to a group of living things) works. It describes the mechanism of natural selection by explaining how the best-adapted individuals are better suited to their environment.

Detailed explanation-4: -Survival of the fittest is an evolutionary concept which means that the organism (or individual) that is most fit is the one that produces the most offspring. Naturally, the most reproductively successful one is able to reproduce because it has managed to survive and mate in its environment.
