The nоvel A Discоvery оf Witches by Deborаh Hаrkness is fаbulous, but the biology is quite off in parts. In fact, the book perpetuates some common misconceptions about evolution. The book describes how witch characteristics, such as the ability to do magic, are encoded in their DNA. When witches needed to be less witch-like over time to avoid persecution, that need “forced mutations… that pushed the magic aside.” (Hmm?) Also, junk/non-coding DNA is described as “waiting to be used in the next evolutionary change. We just don’t know what its purpose is --- yet.” (Huh?) In what ways does the author get biological, and especially evolutionary, concepts wrong? Describe TWO things about the quotes from this book that are not biologically accurate and why. (Note: Magic being supernatural is not one of them. Let’s allow for the supernatural in this question!) (3-6 sentences total)
