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: -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: -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.

Detailed explanation-5: -Yes, fitness in biology refers to the ability of an organism to survive and reproduce in its natural environment.
