Answer:
Natural selection favors the individuals with adaptive genetic variations and leads to evolution of population consisting of members with adaptive genetic traits.
Step-by-step explanation:
Natural selection is the driving force for evolution that favors the genetic variations which impart individuals survival fitness. These individuals are able to produce more progeny. Gradually, natural selection leads to the evolution of population consisting of individuals with favored genetic traits and remove the individuals who did not carry these adaptive traits.
For example, the evolution of antibiotic resistance in bacterial population was the result of natural selection of bacteria having the antibiotic resistance genes.
