I Contain Multitudes: The Microbes Within Us and a Grander View of Life

I Contain Multitudes offers a groundbreaking look at the microscopic organisms that inhabit our bodies and shape the natural world. Science journalist Ed Yong explores the complex, symbiotic relationships between animals and their microbiomes—the trillions of bacteria, viruses, and fungi living within us. Far from being simple germs to be eradicated, these microbes forge our immune systems, influence our behaviors, and drive evolution itself. Written with wit, wonder, and rigorous scientific reporting, this New York Times bestseller reveals how organisms are not isolated individuals, but thriving ecosystems.
