Propolis Cognitive Error Autopsy

Official Correct Choice:
Option A: More offspring than supported
Concept:

A fundamental premise of Darwinian evolution is the inherent capacity of populations to grow exponentially if unconstrained by environmental limits.

Solution:

  • Darwin observed that all species are capable of producing more offspring than the environment can support.
  • This overproduction leads to a struggle for existence (competition for limited resources such as food, space, and mates).
  • Only a fraction of these offspring survive to reproduce, which drives the mechanism of natural selection.


Why other options are incorrect:

  • If organisms produced equal or fewer offspring than resources could support, there would be no intense competition, and a primary driver of natural selection would be absent.

Quality & Fidelity Assurance: Every question on BeambePrep is rigorously curated against the official PMDC syllabus with zero filler, zero out-of-syllabus content, and zero typos. When an authentic past paper originally contained a historical mistake or ambiguity from the examining board (such as UHS or NUMS), BeambePrep faithfully reflects the original paper while detailing the nuance and scientific consensus in the autopsy above.
