Conclusions similar to those drawn by Charles Darwin about evolution were also found by:

Options

A. Lamarck
B. A. Wallace
C. Oparin and Haldane
D. L. Pasteur

Answer

To solve the question regarding which scientist's conclusions about evolution were similar to those drawn by Charles Darwin, we can follow these steps:

### Step-by-Step Solution:

1. **Understand Darwin's Theory**:
- Charles Darwin is best known for his theory of evolution by natural selection. He proposed that organisms evolve over time through a process where individuals with favorable traits are more likely to survive and reproduce.

2. **Identify the Key Concept**:
- The key concept in Darwin's theory is **natural selection**. This means that the environment plays a crucial role in determining which traits are advantageous for survival and reproduction.

3. **Consider Other Scientists**:
- We need to look for other scientists who proposed similar ideas about evolution. The question provides several options, but we need to focus on those who specifically addressed natural selection.

4. **Evaluate Alfred Russel Wallace**:
- Alfred Russel Wallace, a contemporary of Darwin, conducted extensive research on the diversity of plants and animals, particularly in the Malay Archipelago. He independently arrived at conclusions similar to Darwin's, emphasizing natural selection as a mechanism for evolution.

5. **Review Other Options**:
- Other scientists mentioned, such as Lamarck, O'Parrin, Haldane, and Pasteur, had different theories or focused on other aspects of biology that do not directly relate to Darwin's conclusions about natural selection.

6. **Conclusion**:
- Based on the analysis, the scientist whose conclusions about evolution were similar to those of Charles Darwin is **Alfred Russel Wallace**.

### Final Answer:
The correct answer is **Alfred Russel Wallace**.
