A researcher studied the development of resistance to antibiotics by bacteria. She studied several antibiotics to determine how long it took for bacteria to develop resistance. She found that, on average, it took eight years for bacteria to develop resistance to an antibiotic. In some cases, bacteria developed resistance to an antibiotic within a year, and none of the antibiotics were still completely effective on bacteria after 30 years. How is this possible?
