Concept of phylogeny was proposed by :–

Options

A. John Ray
B. Lamarck
C. Ernest Haeckel
D. Darwin

Answer

**Step-by-Step Solution:**

1. **Understanding Phylogeny**: Phylogeny refers to the evolutionary history and the relationships among various biological species based on their shared characteristics and common ancestry.

2. **Identifying the Options**: The question provides four options: John Rainey, Lamarck, Ernst Haeckel, and Darwin. We need to determine which of these individuals proposed the concept of phylogeny.

3. **Evaluating Each Option**:
- **Charles Darwin**: He is known for the theory of natural selection, which explains how species evolve over time. However, he did not specifically propose the concept of phylogeny.
- **Lamarck**: He proposed the theory of inheritance of acquired characteristics, which explains how traits can be passed down based on use or disuse. This is not related to the concept of phylogeny.
- **Ernst Haeckel**: He is credited with coining the term "phylogeny" and is known for his work on the genealogical tree of life and the Biogenetic law, which relates ontogeny (development of an individual) to phylogeny (evolutionary history).
- **John Rainey**: There is no significant contribution related to phylogeny associated with him.

4. **Conclusion**: Based on the evaluation, Ernst Haeckel is the correct answer as he proposed the concept of phylogeny.

5. **Final Answer**: The concept of phylogeny was proposed by Ernst Haeckel.
