The PBS Nova episode “Ghost in Your Genes” has served as an introduction to epigenetics for some members of the general public, biology teachers, and their students. However, this exciting and important field of study is discussed in three pages or less in some of the most recent college-level biology textbooks (e.g., Reese et al., 9th ed.; Starr & Taggart, 13th ed.; Freeman, 4th ed.; Hillis, et al.). With welcome expanded coverage, Carey, an epigenetics researcher, provides details about her field with a clear and captivating narrative that employs analogies, diagrams, a broad array of examples, and an accurate portrayal of the nature of science.
For the novice, Carey uses the analogy of a script and film to explain the difference and interactions between genetics and epigenetics. Shakespeare’s script of Romeo and Juliet has resulted in countless different films and stage productions; it is compared to an individual’s genes. During...
