The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding Speciation**: Speciation is the process by which new species arise. It can occur through various mechanisms, including reproductive isolation. 2. **Types of Speciation**: - **Allopatric Speciation**: This occurs when populations are geographically separated, leading to reproductive isolation. The physical separation prevents interbreeding, allowing for divergence. - **Sympatric Speciation**: This occurs when populations are in the same geographical area but become reproductively isolated. This can happen due to various factors such as behavioral differences, temporal isolation, or polyploidy in plants. - **Transformational Speciation**: This refers to a gradual process where a lineage does not split but rather accumulates genetic changes over time, remaining as a single population. 3. **Identifying the Correct Answer**: The question specifically asks for speciation that occurs within the same area due to reproductive isolation. Since sympatric speciation involves organisms from the same ancestral species becoming reproductively isolated without any physical separation, it is the correct answer. 4. **Conclusion**: The correct answer to the question is **sympatric speciation**. ---
