Darwin explained origin of species through :

Options

A. Hybridization
B. Mutation
C. Acquired characters
D. Natural selection

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks how Darwin explained the origin of species. This involves identifying the key concept or mechanism he proposed in his work.

2. **Reviewing the Options**: The options provided are:
- A) Hybridization
- B) Mutation
- C) Acquired characteristics
- D) Natural selection

3. **Analyzing Darwin's Theory**: In his book "On the Origin of Species," Darwin introduced the concept of natural selection. He proposed that organisms exhibit variations, and those that are better adapted to their environment are more likely to survive and reproduce.

4. **Eliminating Incorrect Options**:
- **Hybridization** (Option A) refers to the mixing of different species or varieties, which is not the primary mechanism Darwin focused on.
- **Mutation** (Option B) involves changes in DNA that can lead to new traits, but Darwin's theory predates the understanding of genetics and mutations.
- **Acquired characteristics** (Option C) refers to traits gained during an organism's lifetime, which is more aligned with Lamarckian evolution, not Darwin's theory.

5. **Identifying the Correct Answer**: Since Darwin emphasized the role of natural selection in the evolution of species, the correct answer is:
- **D) Natural selection**.

6. **Conclusion**: Darwin explained the origin of species through the mechanism of natural selection, where the environment selects for advantageous traits that enhance survival and reproduction.

**Final Answer**: Darwin explained the origin of species through natural selection (Option D).
