Propolis Cognitive Error Autopsy

Official Correct Choice:
Option A: Reptiles and birds
Concept:

Transitional fossils exhibit traits common to both an ancestral group and its derived descendant group.

Solution:

  • Archaeopteryx is one of the most famous transitional fossils in paleontology.
  • It shows strong evidence that birds evolved from theropod reptiles (dinosaurs).
  • It possessed reptilian characters (a long bony tail, teeth, and claws on its wings) alongside avian (bird) characters (feathers and wings).


Why other options are incorrect:

  • It lacks characteristics tying it directly to amphibians, fishes, or mammals in a transitional sense.
