Analogous structures are a result of:

Options

A. Divergent evolution
B. Convergent evolution
C. Shared ancestry
D. Stabilising selection

Answer

**Step-by-Step Solution:**

1. **Understanding Analogous Structures**: Analogous structures are body parts in different species that perform similar functions but do not share a common evolutionary origin.

2. **Identifying Types of Evolution**:
- **Divergent Evolution**: This occurs when two or more related species become more dissimilar over time, often due to different environments or selective pressures.
- **Convergent Evolution**: This is the process where unrelated species develop similar traits or features due to adapting to similar environments or ecological niches.
- **Shared Ancestry**: This refers to species that have evolved from a common ancestor, leading to homologous structures rather than analogous ones.
- **Stabilizing Selection**: This is a type of natural selection that favors average traits in a population and reduces variation.

3. **Analyzing the Options**:
- **Option A (Divergent Evolution)**: Incorrect, as this leads to homologous structures.
- **Option B (Convergent Evolution)**: Correct, as it leads to the development of analogous structures.
- **Option C (Shared Ancestry)**: Incorrect, as this refers to homologous structures.
- **Option D (Stabilizing Selection)**: Incorrect, as this does not specifically relate to the formation of structures.

4. **Conclusion**: The correct answer is **Option B: Convergent Evolution**, as it explains the formation of analogous structures due to independent evolution in different species.
