Which of the following facts develop suspicions in Lamarckism:

Options

A. Human females not born with bored ear pinna although they have been bored for thousand of years
B. Giraffe has long neck to eat leaves of tall tress
C. A stage can run fast to protect against the enemies
D. None of them

Answer

To answer the question "Which of the following facts develop suspicions in Lamarckism?", we need to analyze the options provided and understand the principles of Lamarckism.

### Step-by-Step Solution:

1. **Understand Lamarckism**: Lamarckism is a theory of evolution proposed by Jean-Baptiste Lamarck, which suggests that organisms can pass on traits acquired during their lifetime to their offspring. For example, if a giraffe stretches its neck to reach higher leaves, that trait of a longer neck would be inherited by its offspring.

2. **Examine the Options**:
- **Option A**: Human females not born with bored ear pinna, although they have been bored for thousands of years.
- **Option B**: Giraffe has a long neck to eat leaves of tall grasses.
- **Option C**: A stag can run fast to protect against enemies.
- **Option D**: None of the above.

3. **Analyze Option A**: This option states that human females, despite having bored ears for many generations, are not born with this trait. This contradicts the Lamarckian idea that acquired traits (like ear piercings) can be inherited. If Lamarckism were true, we would expect future generations to be born with bored ears.

4. **Analyze Option B**: This option supports Lamarckism as it describes how giraffes developed long necks due to the need to reach high foliage, which aligns with the theory.

5. **Analyze Option C**: This option also supports Lamarckism, as it suggests that stags developed speed as a protective trait against predators, which could be passed on to future generations.

6. **Conclusion**: Since Option A presents a fact that contradicts the principles of Lamarckism, it raises suspicions about the validity of the theory. Therefore, the correct answer is **Option A**.

### Final Answer:
The fact that develops suspicions in Lamarckism is: **Human females not born with bored ear pinna, although they have been bored for thousands of years.**
