According to recapitulation theory :

Options

A. Every animal begins as an egg
B. Damaged body parts are formed new
C. Offsprings are like parents
D. Ontogeny repeats phylogeny

Answer

**Step-by-Step Text Solution:**

1. **Understanding Recapitulation Theory**: The recapitulation theory, also known as the biogenetic law, was proposed by the scientist Ernst Haeckel. It suggests that the development of an individual organism (ontogeny) follows the same progression as the evolutionary history (phylogeny) of that organism's species.

2. **Key Terms**:
- **Ontogeny**: This refers to the embryonic development of an individual organism.
- **Phylogeny**: This refers to the evolutionary history and development of a species.

3. **Main Concept**: According to the recapitulation theory, during the embryonic development of an individual, it goes through stages that resemble the adult forms of its evolutionary ancestors. Essentially, the development of an organism mirrors the evolutionary stages of its species.

4. **Evaluating Options**:
- **Option A**: "Every animal begins as an egg" - This is incorrect as not all animals start as eggs (e.g., mammals).
- **Option B**: "Damaged body parts are formed new" - This refers to regeneration, not recapitulation.
- **Option C**: "Offsprings are like parents" - This describes asexual reproduction, which is not related to recapitulation theory.
- **Option D**: "Ontogeny repeats phylogeny" - This is the correct statement according to recapitulation theory.

5. **Conclusion**: The correct answer to the question is **Option D: Ontogeny repeats phylogeny**.
