Staphylococcus aureus (staph) is a type of bacteria found on people's skin. These bacteria, along with most other types of bacteria, are usually harmless. They can occasionally cause serious infections that can lead to sepsis or death. Methicillin-resistant Staphylococcus aureus (MRSA) is difficult to treat because of resistance to some antibiotics. Use your knowledge of natural selection to explain how selection for methicillin-resistance in Staphylococcus aureus (MRSA) occurs. Focus on explaining the specifics of how this happens by talking about the variation that has to be present, the characteristics of that variation, impacts on fitness and success of the next generation. Your answer will not require any additional research and will only be a short paragraph based on what you think must be going on here based on other examples of natural selection.

Genetic Evolution

Sexual reproduction produces distinct population variations. Heredity determines the traits and qualities to be passed down to the progeny. Over time, this variation within-species is also affected by the process of human evolution. The study of how genetic variation leads to evolutionary changes is known as genetic evolution. If a trait helps an organism to survive and reproduce, it is more likely to be passed down the generations. It is rare that such traits result in a completely distinct set of traits in descendants than the ancestral population; this can result in the emergence of a new species.
