A new mutation that happens to be beneficial can increase in frequency in a bacterial population very rapidly. If a single individual in the population harbors a mutation that renders it resistant to an antibiotic, there may be millions of resistant bacteria a few hours after antibiotic treatment. The new mutant bacteria would be an example of:
