Detailed explanation-1: -An adaptation is any heritable trait that helps an organism, such as a plant or animal, survive and reproduce in its environment.

Detailed explanation-2: -The ability of an individual to survive and reproduce in its specific environment is fitness. Darwin proposed that fitness is the result of adaptations. An adaptation is any inherited characteristic that increases an organism’s chance of survival.

Detailed explanation-3: -In the crudest terms, fitness involves the ability of organisms-or, more rarely, populations or species-to survive and reproduce in the environment in which they find themselves 6–9. The consequence of this survival and reproduction is that organisms contribute genes to the next generation.

Detailed explanation-4: -The biological concept of fitness is defined as reproductive success. In Darwinian terms, the phrase is best understood as “Survival of the form that will leave the most copies of itself in successive generations."

Detailed explanation-5: -Fitness is the ability to survive and reproduce. This is made possible through the use of adaptations which make an organism better suited to its environment.
