Explain antibiotic resistance observed in bacteria in light of Darwinian selection theory.

Explanation

### Step-by-Step Solution:

1. **Understanding Antibiotic Resistance**:
- Antibiotic resistance refers to the ability of bacteria to survive and grow in the presence of antibiotics that would normally kill them or inhibit their growth. This phenomenon is a significant concern in medicine as it leads to treatment failures.

2. **Introduction to Darwinian Selection Theory**:
