Book excerpt: 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. Key Features 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. Resources 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.
