  1. The fossil hoax debate

  2. The creation-evolution debate

  3. The punctuated equilibrium debate

  4. The mass extinction debate
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The fossil hoax debate refers to the controversy surrounding the authenticity of certain fossils, particularly those that seem to challenge traditional views of evolution or the history of life.

Multiple choice
