The New York Times Bestseller From Pulitzer Prize winner Ed Yong , a groundbreaking, wondrously informative, and vastly entertaining examination of the most significant revolution in biology since Darwin—a “microbe’s-eye view” of the world that reveals a marvelous, radically reconceived picture of life on earth. Every animal, whether human, squid, or wasp, is home to millions of bacteria and other microbes. Pulitzer Prize-winning author Ed Yong, whose humor is as evident as his erudition, prompts us to look at ourselves and our animal companions in a new light—less as individuals and more as the interconnected, interdependent multitudes we assuredly are. The microbes in our bodies are part of our immune systems and protect us from disease. In the deep oceans, mysterious creatures without mouths or guts depend on microbes for all their energy. Bacteria provide squid with invisibility cloaks, help beetles to bring down forests, and allow worms to cause diseases that afflict millions of people. Many people think of microbes as germs to be eradicated, but those that live with us—the microbiome—build our bodies, protect our health, shape our identities, and grant us incredible abilities. In this astonishing book, Ed Yong takes us on a grand tour through our microbial partners, and introduces us to the scientists on the front lines of discovery. It will change both our view of nature and our sense of where we belong in it. “[An] excellent and vivid introduction to our microbiota. . . . infectiously enthusiastic.” — New York Times Book Review “A science journalist’s first book is an excellent, vivid introduction to the all-enveloping realm of our secret sharers.” — New York Times Book Review , Editors' Choice “Offer[s] engrossing-and gross-details about how an invisible world shapes our species…Mr. Yong’s book lives up to its title, containing multitudes of facts presented in graceful, accessible prose….The author wonderfully turns to the humanities again and again to enrich the book’s scientific detail…And he’s funny.” — Wall Street Journal “Not since de Kruif’s classic, “Microbe Hunters,’’ has this invisible world been brought so vividly to life… Yong’s curiosity and humor made me smile and even laugh out loud, much to my husband’s surprise. By the end of the book his sense of wonder for microbes was, well, infectious.” — Boston Globe “For a lesser writer, the temptation to oversimplify the science or to sex up unwarranted conclusions might have proved irresistible. Mr Yong expertly avoids these pitfalls…. I Contain Multitudes bowls along wonderfully without it. His hero, Sir David [Attenborough], would surely approve.” — The Economist (A Best Book of 2016) “Beautifully written. . . . Yong - who like Carl Zimmer belongs to the highest tier of science journalists at work today - weaves revelatory anecdotes and cutting-edge reporting into an elegant, illuminating page-turner.” — Minneapolis Star Tribune (A Best Book of 2016) “Beautiful, smart, and sometimes shocking.” — Wired “Masterful . . . a tale that shifts our personal cosmology and compels us to look anew at the world." — The Guardian (A Best Book of 2016) “A delightful, witty book. Yong vividly describes the intricate alliances forged by microbes with every other organism on the planet — Science “[Yong’s] enthusiasm and wonder are propulsive. While [he] acknowledges that the questions outnumber the answers in this relatively nascent field, he thrills to the potential inherent in what scientists have already learned about microbes’ astonishing powers. As a result, so do we.” — The Week “The strong narrative, rigorous reporting and fluid writing make I Contain Multitudes one of the most essential science books of the year. Yong’s wit, and endearing inability to pass up an opportunity for wordplay, are just a couple of the many bonuses that make it enjoyable, too.” — Philly Voice “Fascinating and elegantly written. . . . Yong peels the veneer of the visible to reveal the astonishing complexity of life thriving beneath and within the crude confines of our perception. . . . masterful [and] intensely interesting.” — Brainpickings (A Best Science Book of 2016) “[A] informative and infectiously readable book.” — Cell “An exceptionally informative, beautifully written book that will profoundly shift one’s sense of self to that of symbiotic multitudes.” — Kirkus Reviews   (starred review) “Bottom line: don’t hate or fear the microbial world within you. Appreciate its wonders. After all, they are more than half of you.” — Booklist (starred review) “In this powerful treatise on the benefits of ecological thinking, Yong describes the vast and ancient yet still poorly understood world of microbiota, whose study in isolation has yielded poor results. As researchers have started to examine microscopic communities, they’ve produced new insights on a range of biological systems and animal behaviors.” — Publishers Weekly 's Best Books of the Year
