Answer

To solve the question "He helped discover evolution, and then become extinct," we need to analyze the options provided and identify who this statement refers to.

### Step-by-Step Solution:

1. **Understanding the Statement**: The statement suggests that the person played a significant role in the discovery of evolution and later became extinct. This implies that the individual contributed to evolutionary theory but is no longer recognized or has faded from prominence.

2. **Analyzing the Options**:
- **Option A: Wallace** - Alfred Russel Wallace is known for his work on natural selection alongside Charles Darwin. He independently conceived the theory of evolution through natural selection.
- **Option B: Mendel** - Gregor Mendel is known for his work in genetics, particularly the laws of inheritance, but he did not directly contribute to the theory of evolution.
- **Option C: Bateson** - William Bateson was a geneticist who contributed to the understanding of heredity, but he is not primarily known for his work on evolution.
- **Option D: Lamarck** - Jean-Baptiste Lamarck proposed an early theory of evolution based on the inheritance of acquired characteristics, but his ideas were largely discredited over time.

3. **Identifying the Correct Answer**:
- While both Wallace and Darwin contributed significantly to the theory of evolution, Wallace's contributions are often overshadowed by Darwin's fame. This could be interpreted as him "becoming extinct" in terms of recognition in the public eye.
- Therefore, the statement "He helped discover evolution, and then become extinct" most accurately refers to **Option A: Wallace**.

### Conclusion:
The correct answer is **Option A: Wallace**.
