Question

Quizplus · Accepted Answer

The development of penicillin-resistant bacteria is an example of microevolution, which refers to small-scale changes within a species over time, such as the development of resistance to antibiotics. This occurs due to natural selection where bacteria with mutations that confer resistance to penicillin are more likely to survive and reproduce, spreading the resistance trait through the population.
