Why evolution is like a network, not a family tree—and why it matters for understanding the health of all living things In The Network of Life , David Mindell explains why the conventional narrative of evolution needs to evolve. Ever since Darwin, evolution has largely been thought to work like a family tree in which species are related through a series of branching events. But, today, a growing knowledge of the ways species share genetic materials in a process known as horizontal evolution has revealed that evolution is actually a network of shared genealogy in which species are more interconnected than previously thought. In this book, Mindell presents this new narrative of life’s evolution and its profound implications for all life on Earth. The Network of Life describes the drivers of horizontal evolution—interbreeding and genetic recombination, the merger of species, horizontal gene transfer, and coevolution. The network view of evolution that emerges supports a new symbiotic theory of health, which holds that the future health of humans, other species, and our shared environments depends on evolution and adaptation across life’s network. Difficult times lie ahead for many of Earth’s species as climates and habitats transform. At the same time, new and altered life-forms are arising and spreading in association with human activities. We are also learning to reshape and create life by mimicking the mechanisms of horizontal evolution, and we are coevolving with technology as we enhance our bodies, brains, and life spans. The Network of Life shows why and how increasing our knowledge of horizontal evolution can provide critical lessons as we navigate our looming challenges. Reviews "A Choice Outstanding Academic Title of the Year" "Mr. Mindell is an excellent guide to this complex picture. . . . [The Network of Life] offers good, solid science and a clear illustration of an emerging perspective that is beginning to pay dividends in our understanding of evolution."--- David P. Barash, Wall Street Journal "Eye-opening analysis. . . . The heady ideas [in The Network of Life] will change how readers understand some of biology's most fundamental concepts." ― Publishers Weekly "A perspective-shifting reconceptualization of evolution."--- Wade Lee-Smith, Library Journal "I am quite sure that Darwin, were he alive today, would embrace this added view of evolution and would be foremost in its supporters. . . . The book is beautifully written and thought-provoking in myriad ways."--- David Gascoigne, Travels with Birds "A valuable book for professionals and nonprofessionals interested in the origin and evolution of life."--- L. T. Spencer, Choice "An important book."— David Lorimer, Paradigm Explorer "This is an outstanding and thought-provoking book... [The Network of Life] is well written and will appeal to both the curious public and those with expertise." --- Jim Lynch The Biologist "The Network of Life is engaging and contains exciting, controversial points, especially for evolutionary biologists, but also for a wide range of readers... There are many rewards to reading the book... Part I [provides] an original approach and view of evolution... Part II is fascinating, speculative, futuristic and clearly intended for a general audience; however, the word "speculative" is not a criticism, it is a good bet that much of what is said there will happen in the not-too-distant future." --- Arturo Becerra, The Quarterly Review of Biology “Mindell’s wide-ranging inquiry into the network of life is as mind-expanding as it is bold. Mindell does nothing less than trace the outlines of a new view of life and the implications of humanity’s coexistence with nature, technology, and an ever-changing planet. From bacteria to birds, from Aristotle to Emily Dickinson (and of course Darwin), the breadth of scholarship and integration of emerging concepts is breathtaking.” —Scott V. Edwards, Harvard University “In this excellent book, David Mindell presents a new picture of evolution. He compellingly argues that decentralization brought about by horizontal evolution is indispensable for biological innovation. Highly recommended for anyone interested in quickly grasping the recent paradigm shift in evolutionary biology.” —Eugene Koonin, National Institutes of Health “Exploring the intersection of human evolution and the history of life on Earth, The Network of Life asks us to envision the future of humanity and biological diversity in the context of the benefits and threats of an increasingly technological world. This is an expansive and stimulating book.”— Joel L. Cracraft, American Museum of Natural History “I’d always thought of evolution as primarily a matter of ‘descent with modification’—a treelike process, only sometimes interrupted by horizontal exchange. Lately, however, I’m coming to realize that the important events in evolution—those leading to evolutionary innovation—might well b
