Question

Quizplus · Accepted Answer

Increased resistance of bacteria to an antibiotic that is used to kill them is a clear example of evolution that has been readily observed. As bacteria are exposed to an antibiotic, those with genetic mutations that provide resistance to the antibiotic are more likely to survive and reproduce, passing on their resistant genes to their offspring. Over time, the population of bacteria will evolve to become more resistant to the antibiotic, making it less effective. This is a well-documented phenomenon in the field of microbiology.
