Ed Yong’s 2016 New York Times bestseller arrived at a pivotal moment in biology, introducing a general audience to one of the most profound scientific shifts since Darwin: the discovery that every animal—including every human—is not an individual at all, but a living ecosystem. The trillions of microbes that inhabit us sculpt our organs, educate our immune systems, guide our behavior, and shape our identities in ways science is only beginning to understand. Yong takes this science far beyond the human body, revealing how bacteria give Hawaiian squid their bioluminescence, how microbes allow beetles to digest trees, and how the entire animal kingdom is built on invisible partnerships that have been evolving for billions of years. Kirkus called it “an exceptionally informative, beautifully written book that will profoundly shift one’s sense of self to that of symbiotic multitudes.” Carl Zimmer described it as a book that makes you look at the living world “in a new way.”
For anyone drawn to the story of how we are transitioning from a worldview of separation and competition to one of interdependence and partnership, this book makes that shift feel not just intellectually compelling but personally true.
