Darwin's Reach 21st Century Applications of Evolutionary Biology
The application of evolutionary biology addresses a wide range of practical problems in medicine, agriculture, the environment, and society. Such cutting-edge applications are emerging due to recent advances in DNA sequencing, new gene editing tools, and computational methods. This book is about applied evolution – the application of the principles of and information about evolutionary biology to diverse practical matters. Although applied evolution has existed, unrecognized, for a very long time, today’s version has a much wider scope. Evolutionary medicine has formed into its own discipline. Evolutionary approaches have long been employed in agriculture and in conservation biology. But Darwin’s reach now extends beyond just these three fields. It now also includes forensic biology and the law. Ideas from evolutionary biology can be used to inform policy regarding foreign affairs and national security. Applied evolution is not only interdisciplinary, but also multidisciplinary. Consequently, this book is for experts in one field who are interested in expanding their evolutionary horizons. It is also for students, at the undergraduate and graduate levels. One of the public relations challenges faced by evolutionary biology is that most people do not see it being all that relevant to their daily lives. Even many who accept evolution do not grasp how far Darwin’s reach extends. This book will change that perception.
- Emphasizes the expanding role evolutionary biology has in today’s world.
- Includes examples from medicine, law, agriculture, conservation, and even national security
- Summarizes new technologies and computational methods that originated as innovations based in part or whole on evolutionary theory.
- Current. Has extensive coverage of the COVID-19 pandemic and other recent topics.
- Documents the important role evolution plays in everyday life.
- Illustrates the broadly interdisciplinary nature of evolutionary theory.
The applications of evolutionary biology are far too numerous to include in just one book. Plus, new scientific findings emerge almost every day underscoring the central role evolution plays in our lives. The author has established a blog site to highlight these fascinating discoveries.

In Darwin’s Reach, Norman Johnson takes Dobzhansky’s assertion that ‘nothing in biology makes sense outside the light of evolution’ to a new level. This remarkable book demonstrates how an evolutionary ‘lens’ can deepen our understanding of critical issues. With compelling prose and masterful scientific storytelling, Johnson shows exactly how powerfully evolution can illuminate and transform a remarkably wide range of human concerns, disciplines and domains. An invaluable resource for students, teachers, and anyone interested in gaining a deeper understanding of the human experience–past, present and future.

Darwin’s Reach is an intellectual tour de force that synthesizes findings about evolution from numerous fields and concretely shows how insights from pest management can help us manage invasive species as well as invasive cancers, antibiotic resistance, and much, much more. Norman Johnson is not only an eloquent tour guide who clearly unpacks complex evolutionary principles, experiments, and insights, but he’s also a public relations expert showing us how and why evolution matters to us all. This is a must read for anyone interested in evolutionary medicine, sustainable agriculture, the biodiversity crisis, and, more generally, in the intellectual challenges of applying scientific knowledge.

"… the manifold areas of applied evolutionary biology have not been comprehensively described until now. Norman A. Johnson, at the University of Massachusetts – Amherst, has stepped up to the challenge…
Johnson starts with present-day issues, such as phage therapy, in which selection for phage resistance in pathogenic bacteria may reduce their resistance to antibiotics providing an opportunity to introduce natural selection and costs of adaptation. The chapter "Going Viral" treats viral epidemics, focusing on the SARS-Cov-2 pandemic and illustrating the use of phylogenetic inference in tracing the spread of such epidemics….
Johnson has done a real service in his well- researched (with about 900 literature citations) review of a very diverse, sprawling subject. He has written a fine book, a remarkably comprehensive survey of an important dimension of evolutionary biology. "
Douglas Futuyma in Evolution, 2023
"Johnson undertakes a wide variety of topics… including evolutionary medicine, pandemics like COVID-19 and HIV/AIDS, mosquito-borne diseases, personalized medicine, cancer, agriculture, biodiversity, and invasive species. He concludes with a few chapters on evolution and society, including genetic analysis in criminal investigations, warfare, and the non-existence of human biological races…I would not hesitate to suggest it as supplementary reading for interested undergraduates. It should provide useful insights for evolutionary biologists, geneticists and health professionals. "
