How do superbugs evolve?

The doctor may then try a different antibiotic. Any bacteria that survive this second treatment may slowly develop a resistance to it, as well. As this cycle continues, the germ’s ability to adapt allows it to survive many different antibiotic treatments, and it becomes a superbug.

What is a superbug and why does it occur?
