"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

"[An] excellent and vivid introduction to our microbiota, or microbiome, the all-enveloping realm of our microbes . . . I Contain Multitudes has a terrific story to tell . . . [Yong] is infectiously enthusiastic about microbes, and he describes them with verve . . . Even the book''s endnotes are rich with interesting asides, swarming with interesting sidelights, a teeming microbial world." - New York Times Book Review (A NYT Notable Book of 2016)

"[An] excellent and vivid introduction to our microbiota. . . . infectiously enthusiastic." - New York Times Book Review

"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)
