A biologist is interested in the chronological order of major evolutionary events and the diversification of different groups of organisms. Which two consecutive units in the "Brief Contents" would be most crucial for understanding this progression?

  • A: Unit 2: The Cell and Unit 3: Genetics
  • B: Unit 3: Genetics and Unit 4: Mechanisms of Evolution
  • C: Unit 4: Mechanisms of Evolution and Unit 5: The Evolutionary History of Biological Diversity
  • D: Unit 6: Plant Form and Function and Unit 7: Animal Form and Function

Explanation

Unit 4, "Mechanisms of Evolution," lays the groundwork for how evolution occurs, including "Descent with Modification" and "The Origin of Species." Unit 5, "The Evolutionary History of Biological Diversity," then builds upon this by covering the "Phylogeny and the Tree of Life" and the diversification of various life forms like Bacteria, Archaea, Protists, Plants, Fungi, and Animals, essentially tracing the chronological path of life's major evolutionary events and diversification.
