Antibiotic resistance

The video explains how bacteria develop antibiotic resistance, often by producing proteins that block the antibiotic's entry into cells. This resistance is a result of natural selection, similar to how species evolve. The MRSA bacterium is highlighted as a prime example, having developed resistance to penicillin just four years after its mass production began.

Explain the process of natural selection in the context of antibiotic resistance.
