MRSA bacteria become resistant to antibiotics through natural selection.
MRSA bacteria have evolved to become resistant to antibiotics through the process of natural selection. When exposed to antibiotics, bacteria with genetic variations that enable them to survive will be the ones to reproduce and pass on these traits to their offspring, leading to a population of antibiotic-resistant bacteria. This adaptation occurs over time and is a result of the selective pressure exerted by the presence of antibiotics.
