Several other nurses comment that the change is “all about money.” The charge nurse must educate the staff about the importance of this new policy. Which explanation by the charge nurse is most appropriate?

Describe how mutations initially arise in an organism’s genotype, affecting specific alleles, and how these changes can influence the phenotype. Discuss how natural selection acts on these phenotypic variations, ultimately driving evolution in a population. Provide examples to illustrate your explanation.
