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 gets selected by nature
D. All mammals except whales and camels have seven cervical vertebrae

Answer

To solve the question "Select the correct statement from the following," we will analyze each of the provided statements one by one.

### Step-by-Step Solution:

1. **Evaluate the First Statement:**
- **Statement:** "Mutations are random and directional."
- **Analysis:** Mutations are indeed random; however, they are not directional. They occur without a specific direction or purpose. Therefore, this statement is **incorrect**.

2. **Evaluate the Second Statement:**
- **Statement:** "Darwinian variations are small and directionless."
- **Analysis:** Darwinian variations (which refer to the variations that arise through natural selection) are typically small, but they can also be directional as they can lead to adaptations that are beneficial in a particular environment. Hence, this statement is also **incorrect**.

3. **Evaluate the Third Statement:**
- **Statement:** "Fitness is the end result of ability to adapt and get selected by nature."
- **Analysis:** This statement is accurate. Fitness refers to the reproductive success of an organism, which is indeed a result of its ability to adapt to the environment and be selected by nature. Thus, this statement is **correct**.

4. **Evaluate the Fourth Statement:**
- **Statement:** "All mammals except whales and camels have seven cervical vertebrae."
- **Analysis:** This statement is incorrect. While most mammals have seven cervical vertebrae, there are exceptions beyond just whales and camels. For example, some sloths and manatees have different numbers of cervical vertebrae. Therefore, this statement is **incorrect**.

### Conclusion:
After analyzing all the statements, the only correct statement is the third one: "Fitness is the end result of ability to adapt and get selected by nature."

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