Question Detail
Question
Which geological process is responsible for the creation of distinct biogeographic realms like the Neotropical and Afrotropical?
Correct Answer
Option A is the correct answer.
Detailed Explanation
Continental drift separated landmasses over millions of years, isolating faunas and allowing them to evolve independently. Glacial retreat affects ranges but not the fundamental division of global realms.
Hint
This involves the movement of entire continents over millions of years.
