Question

Quizplus · Accepted Answer

Bacteria developing increased resistance to antibiotics is a clear example of evolution in action. As antibiotics are used to kill bacteria, those with genetic mutations that allow them to survive the antibiotic treatment will be more likely to survive and reproduce, passing on their resistant traits to their offspring. Over time, this can lead to the evolution of entirely new bacterial strains that are resistant to multiple antibiotics.
