Detailed explanation-1: -Adaptations that result from natural selection are expected to increase the fitness of an organism.
Detailed explanation-2: -An adaptation is a characteristic that enhances the survival or reproduction of organisms that bear it, relative to alternative character states (especially the ancestral condition in the population in which the adaptation evolved).
Detailed explanation-3: -B) An organism adapting to its environment can increase an organism’s fitness by continually adapting and experiencing a change in the environment. Every time an organism is exposed to a change in the environment, they become sensitized or used to that change and therefore increase their fitness or response.
Detailed explanation-4: -Key Points. Natural selection can cause microevolution (change in allele frequencies), with fitness-increasing alleles becoming more common in the population. Fitness is a measure of reproductive success (how many offspring an organism leaves in the next generation, relative to others in the group).
