Ontogeny Recapitulates Phylogeny' is narrated in which of the evidences for organic evolution?

Options

A. Palaeontological evidence
B. Physiological evidence
C. Embryological evidence
D. Anatomical evidence

Explanation

**Step-by-Step Solution:**

1. **Understanding the Concept:**
- The phrase "Ontogeny Recapitulates Phylogeny" refers to a theory proposed by Ernst Haeckel in 1866, which suggests that the development of an individual organism (ontogeny) follows the same progression as the evolutionary history of that organism's species (phylogeny).

2. **Identifying the Key Terms:**
- **Ontogeny:** This is the study of the development of an organism from fertilization to maturity, particularly focusing on the embryonic stage.
- **Phylogeny:** This refers to the evolutionary history and relationships among species.

3. **Evaluating the Options:**
- **Paleontological Evidence:** This relates to the study of fossils and does not specifically address embryonic development.
- **Physiological Evidence:** This pertains to the functions and processes within living organisms, which is not directly related to embryonic stages.
- **Embryological Evidence:** This is concerned with the development of embryos and is directly related to the concept of ontogeny recapitulating phylogeny, as it examines how embryonic development reflects ancestral forms.
- **Anatomical Evidence:** This involves the structure of organisms, which does not specifically focus on the developmental stages.

4. **Conclusion:**
- The correct answer is **Embryological Evidence** because the concept of "Ontogeny Recapitulates Phylogeny" directly relates to the study of embryonic development and how it reflects the evolutionary history of an organism.

**Final Answer:**
- The phrase "Ontogeny Recapitulates Phylogeny" is narrated in **Embryological Evidence**.
