Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Understanding systematics.
- Systematics is the branch of biology that deals with classification and evolutionary relationships of organisms.
Step 2: Invertebrate classification.
- Invertebrates are animals without a backbone, including mollusks, arthropods, and annelids.
- Proper classification requires extensive study of anatomy, morphology, and reproduction.
Step 3: Libbie Henrietta Hyman's contribution.
- Hyman was an American zoologist who authored the 6-volume series “The Invertebrates”.
- She studied detailed anatomy and physiology of invertebrates, establishing a standardized classification.
Step 4: Comparison with others.
- Heackel: proposed the tree of life concept but not in-depth in invertebrates.
- Leeuwenhoek: pioneer in microscopy, not systematics.
- Robert E. Grant: early 19th-century zoologist, contributed to marine biology but Hyman modernized invertebrate systematics.
Step 5: Conclusion.
Hence, the pioneer of invertebrate systematics is Libbie Henrietta Hyman.
