Explanation:
Detailed explanation-1: -In recent years “SuperBugs” (bacteria that aren’t effected by antibiotics) are becoming more and more common. How could natural selection explain this? We have always had the same amount of superbugs; modern media just discusses them more. There is no reliable data on the origin of super bugs.
Detailed explanation-2: -Through mutation and selection, bacteria can develop defense mechanisms against antibiotics. For example, some bacteria have developed biochemical “pumps” that can remove an antibiotic before it reaches its target, while others have evolved to produce enzymes to inactivate the antibiotic.
