Question

The animals that evolved into the first amphibians during evolutionary history were:

• A. ( \text{Archaeopteryx} )
• B. ( \text{Salamander} )
• C. ( \text{Coelacanth} )
• D. ( \text{Lobe fins} )

Answer 1

The Correct Option is D

The first amphibians are believed to have evolved from a group of bony fishes known as lobe-finned fishes (Sarcopterygii). These fishes possessed fleshy, lobed fins supported by bones, which are considered to be the precursors to the limbs of tetrapods (four-limbed vertebrates), including amphibians. Archaeopteryx is an extinct bird-like dinosaur considered a transitional fossil between non-avian feathered dinosaurs and modern birds. Salamanders are amphibians themselves, not the ancestors of the first amphibians. Coelacanths are another group of lobe-finned fishes, but the specific lineage that led to amphibians is considered to be the extinct group of lobe-finned fishes more closely related to tetrapods. "Lobe fins" refers to the characteristic fins of these ancestral fish.
