8. The bacterium Staphylococcus aureus causes skin infections commonly called staph infections. One antibiotic that has been used to treat staph infections is methicillin. However, resistance to this antibiotic has become a widespread problem. The graph below shows the percentage of S. aureus strains that have become resistant to methicillin over a 20-years period in the United States. As you may have heard, methicillin-resistant S. aureus strains are called MRSA. Explain these data. Is evolution occurring? If so, propose a hypothesis to explain why S. aureus populations are evolution with regard to antibiotic resistance.
