|
Directional natural selection
|
|
|
Diversifying natural selection
|
|
|
Stabilizing natural selection
|
|
|
Convergent natural selection

Explanation:
Detailed explanation-1: -Survival of the Fittest (Natural Selection) When bacteria are initially exposed to an antibiotic, those most susceptible to the antibiotic will die quickly, leaving any surviving bacteria to pass on their resistant features to succeeding generations.
Detailed explanation-2: -Antibiotic resistance is a stunning example of evolution by natural selection. Bacteria with traits that allow them to survive the onslaught of drugs can thrive, re-ignite infections, and launch to new hosts on a cough. Evolution generates a medical arms race.
