Detailed explanation-1: -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-2: -Evolutionary adaptation, or simply adaptation, is the adjustment of organisms to their environment in order to improve their chances at survival in that environment.

Detailed explanation-3: -Natural selection is a process where organisms with beneficial and advantageous traits survive better than others. As generations pass, the species will have many organisms that have that advantageous trait.

Detailed explanation-4: -In the first four editions of On the Origin of Species, Darwin had used the phrase “natural selection". In Chapter 4 of the 5th edition of The Origin published in 1869, Darwin implies again the synonym: “Natural Selection, or the Survival of the Fittest".

Detailed explanation-5: -adaptation, in biology, the process by which a species becomes fitted to its environment; it is the result of natural selection’s acting upon heritable variation over several generations.
