Propolis Cognitive Error Autopsy

Official Correct Choice:
Option A: Survival in the struggle for existence is random
Concept:

Natural selection is highly deterministic, not a random lottery.

Solution:

  • The statement "Survival in the struggle for existence is random" is strictly incorrect.
  • Darwin's theory explicitly states that survival is heavily influenced by inherited traits.
  • Organisms with variations best suited to the local environment are naturally selected to survive and reproduce, making the process decidedly non-random.


Why other options are incorrect:

  • B, C, and D are all core, accurate tenets of Darwin's theory: Fit individuals reproduce more, causing a gradual accumulation of advantageous traits that can eventually lead to speciation.
