Final answer:
Yes, the mutation rate itself is subject to natural selection. Beneficial mutations that enhance an organism's ability to survive and reproduce are more likely to be passed on to future generations, while harmful mutations are more likely to be eliminated through natural selection.
Step-by-step explanation:
Yes, the mutation rate itself is subject to natural selection. While mutations occur randomly, whether they are beneficial, harmful, or neutral determines their likelihood of being selected for or against in a population. Beneficial mutations that enhance an organism's ability to survive and reproduce are more likely to be passed on to future generations, while harmful mutations are more likely to be eliminated through natural selection. This process contributes to evolutionary change over time.
