Question:
Transitional form between fishes and amphibians
Transitional form between fishes and amphibians
Show Hint
Remember transitional forms as evolutionary bridges: Eusthenopteron → Fish-Amphibian; Archaeopteryx → Reptile-Bird; Cynognathus → Reptile-Mammal. Focus on morphological features indicating transition.
Updated On: Jun 9, 2026
- Seymouria
- Eusthenopteron
- Cynognathus
- Archaeopteryx
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Eusthenopteron is a lobe-finned fish showing adaptations for transition to amphibians, e.g., limb-like fins, lungs. Seymouria is reptiliomorph; Cynognathus → mammal-like reptiles; Archaeopteryx → bird-like dinosaur.
