Propolis Cognitive Error Autopsy

Official Correct Choice:
Option C: South American mainland
Concept:

Biogeography provides critical evidence for evolution, illustrating how geographical proximity influences species relationships.

Solution:

  • During his voyage on the HMS Beagle, Darwin noted that the unique flora and fauna of the Galapagos Islands were closely related to those on the nearest mainland.
  • The Galapagos Islands are located off the western coast of South America.
  • Therefore, the species on the islands most closely resembled those living on the South American mainland, suggesting they were colonized by strays from there that subsequently diversified.


Why other options are incorrect:

  • The flora and fauna did not closely resemble species from Europe or North America, which geographically and climatically do not share recent evolutionary history with the Galapagos.
