According to Darwin, if new variations are to be inherited they should be:

Options

A. 1)Selected by the nature through competition and adaption
B. 2)Arised through saltations
C. 3)Defeated in the struggle for existence
D. 4)Rejected by the nature

Answer

To answer the question regarding Darwin's views on the inheritance of new variations, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Darwin's Theory**: Begin by recognizing that Charles Darwin's theory of evolution is based on the concept of natural selection. According to Darwin, variations within a species are crucial for the process of evolution.

2. **Identifying Key Concepts**: The key concepts in Darwin's theory include:
- Struggle for existence
- Survival of the fittest
- Natural selection
- Inheritance of variations

3. **Evaluating the Options**: The question presents four options regarding how new variations can be inherited:
- A) Selected by nature through competition and adaptation
- B) Arise through saltation
- C) Defeated in the struggle for existence
- D) Rejected by nature

4. **Analyzing Each Option**:
- **Option A**: Selected by nature through competition and adaptation. This aligns with Darwin's theory, as only those variations that help an organism survive and reproduce will be passed on to the next generation.
- **Option B**: Arise through saltation. This suggests sudden changes, which is not supported by Darwin’s gradual process of evolution.
- **Option C**: Defeated in the struggle for existence. This is incorrect because those that are defeated do not pass on their variations.
- **Option D**: Rejected by nature. This is also incorrect, as rejected traits do not get inherited.

5. **Conclusion**: The correct answer is **Option A**: Selected by nature through competition and adaptation. This reflects Darwin's belief that for new variations to be inherited, they must contribute to the organism's ability to survive and reproduce in its environment.
