Gr 6 Up–This book provides an excellent introduction to genetic engineering for younger readers. Five sections address the complicated issue from a variety of perspectives: crossbreeding to save endangered animals; using genetics to “resurrect” extinct animals; cloning; breeding animals selectively to create designer pets; and using gene therapy for medicinal purposes. The author provides a balanced view of these scientific advances, paying careful attention to highlight their benefits and potential drawbacks. For example, while it’s wonderful that we can save endangered species, discover solutions to human illnesses and diseases, and create nonallergenic pets, what are the downsides? Should society support these efforts just because the opportunity exists? Probing questions such as these are peppered throughout, reminding readers of the ethical conundrums. The book is written in a friendly, age-appropriate style with genetic engineering terms and procedures well defined. Young readers will enjoy popular culture references to
Jurassic Park and
Frankenstein that make the complicated subject matter more relatable. Colorful captioned photographs and larger font headings balance the text in each chapter. The work also aids future reading and reference with an extensive bibliography, source notes, and glossary.
VERDICT Libraries looking to update their science collections for middle grade students will want to consider this nicely packaged publication, keeping in mind that with rapid changes in technology, it may soon be supplanted by newer works.
