The correct Answer is:
To answer the question "Who raised the status of hemichordates from subphylum to phylum?", we can follow these steps: ### Step-by-Step Solution: 1. **Understand Hemichordates**: - Hemichordates are a group of marine animals that were initially classified under the subphylum of the phylum Chordata. They are characterized by having a notochord in the anterior region of their body. 2. **Historical Classification**: - Initially, hemichordates were considered a subphylum within the protochordates, which include other groups like urochordates and cephalochordates. 3. **Significance of Hemichordates**: - Hemichordates are important because they serve as a connecting link between echinoderms (non-chordates) and chordates. This unique position highlights their evolutionary significance. 4. **Change in Classification**: - Due to their characteristics and evolutionary importance, hemichordates were later elevated from a subphylum to a full phylum. 5. **Identify the Contributor**: - The question specifically asks who was responsible for this change in classification. The correct answer is Belfort, who recognized the significance of hemichordates and elevated their status. ### Final Answer: Belfort raised the status of hemichordates from subphylum to phylum. ---
