I Contain Multitudes

Joining the ranks of popular science classics like The Botany of Desire and The Selfish Gene, 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. 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.
Book Description

A groundbreaking, marvelously informative “microbe’s-eye view” of the world that reveals a radically reconceived picture of life on earth.

For most of human existence, microbes were hidden, visible only through the illnesses they caused. When they finally surfaced in biological studies, they were cast as rogues. Only recently have they immigrated from the neglected fringes of biology to its center. Even today, many people think of microbes as germs to be eradicated, but those that live with us—the microbiome—are invaluable parts of our lives.

I Contain Multitudes lets us peer into that world for the first time, allowing us to see how ubiquitous and vital microbes are: they sculpt our organs, defend us from disease, break down our food, educate our immune systems, guide our behavior, bombard our genomes with their genes, and grant us incredible abilities. While much of the prevailing discussion around the microbiome has focused on its implications for human health, Yong broadens this focus to the entire animal kingdom, giving us a grander view of life.

With humor and erudition, Ed Yong prompts us to look at ourselves and our fellow animals in a new light: less as individuals and more as the interconnected, interdependent multitudes we assuredly are. When we look at the animal kingdom through a microbial lens, even the most familiar parts of our lives take on a striking new air. We learn the secret, invisible, and wondrous biology behind the corals that construct mighty reefs, the glowing squid that can help us understand the bacteria in our own guts, the beetles that bring down forests, the disease-fighting mosquitoes engineered in Australia, and the ingredients in breast milk that evolved to nourish a baby’s first microbes. We see how humans are disrupting these partnerships and how scientists are now manipulating them to our advantage. We see, as William Blake wrote, the world in a grain of sand.

I Contain Multitudes is the story of these extraordinary partnerships, between the familiar creatures of our world and those we never knew existed. It will change both our view of nature and our sense of where we belong in it.
