Explanation

**Step-by-Step Text Solution:**

1. **Understanding Fitness in Evolution**: Fitness in the context of evolution refers to an organism's ability to survive and reproduce in its environment. It is not just about physical strength but encompasses the overall adaptability of a species to changing conditions.

2. **Darwinian Theory of Natural Selection**: According to Darwin's theory, species that can adapt to their environment are more likely to survive and reproduce. This process is known as natural selection, where advantageous traits become more common in a population over generations.

3. **The Role of Adaptation**: When environmental conditions change, species face two choices: adapt to the new conditions or face extinction. Those that adapt will pass on their advantageous traits to the next generation, while those that cannot adapt may die out.
