Propolis Cognitive Error Autopsy

Official Correct Choice:
Option B: Adaptation
Concept:

Darwin's primary focus was explaining how organisms become so perfectly suited to their specific environments.

Solution:

  • The central theme of Darwin's "Origin of Species" is how populations change over time to become better fitted to their local environments.
  • This process of modifying traits for survival is known as Adaptation.
  • Natural selection is the mechanism, and adaptation is the resulting biological outcome that Darwin meticulously documented.


Why other options are incorrect:

  • Origin of life: Darwin famously did not address how the very first spark of life began; he only addressed how life diversified after it existed.
  • Speciation / Extinction: While discussed as consequences of natural selection, the driving narrative of the book is the mechanical process of adaptation.
