Select the correct statement from the following:

Options

A. Mutations are random and directional
B. Darwinian variations are small and directionless
C. Fitness is the end result of the ability to adapt and get selected by nature
D. All mammals except whales and camels have seven cervical vertebrae

Explanation

To solve the question, we need to evaluate each of the provided statements and determine which one is correct.

### Step-by-Step Solution:

1. **Evaluate Option A**: "Mutations are random and directional."
- **Analysis**: Mutations occur randomly and are not directional. They can lead to various outcomes, but they do not follow a specific direction or pattern.
- **Conclusion**: This statement is incorrect.

2. **Evaluate Option B**: "Darwinian variations are small and directionless."
- **Analysis**: Darwinian variations refer to the small changes that occur in populations over time. While these variations can be small, they are not necessarily directionless as they can lead to adaptations that are beneficial for survival.
- **Conclusion**: This statement is incorrect.

3. **Evaluate Option C**: "Fitness is the end result of the ability to adapt and get selected by nature."
- **Analysis**: This statement accurately describes the concept of fitness in evolutionary biology. Fitness refers to an organism's ability to survive and reproduce in its environment, which is indeed a result of adaptation and natural selection.
- **Conclusion**: This statement is correct.

4. **Evaluate Option D**: "All mammals except whales and camels have seven cervical vertebrae."
- **Analysis**: This statement is incorrect. Most mammals, including humans, have seven cervical vertebrae, but manatees are an exception, not whales and camels.
- **Conclusion**: This statement is incorrect.

### Final Answer:
The correct statement is **Option C**: "Fitness is the end result of the ability to adapt and get selected by nature."
