Propolis Cognitive Error Autopsy

Official Correct Choice:
Option A: Archaeopteryx
Concept:

Transitional fossils provide a snapshot of evolution in progress, linking major vertebrate groups.

Solution:

  • Archaeopteryx (meaning "ancient wing") is the most famous fossil linking non-avian theropod dinosaurs to modern birds.
  • It lived during the Late Jurassic period and possessed a mix of reptilian features (teeth, long bony tail) and avian features (flight feathers, wishbone).


Why other options are incorrect:

  • Equus: The modern genus of horses, zebras, and donkeys.
  • Dawn horse (Eohippus/Hyracotherium): An early fossil ancestor of the horse, not a bird.
  • Python: A modern extant genus of non-venomous snakes.
