Ed Yong writes popular science about animals, microbes, perception and the hidden biological systems that shape everyday life. I Contain Multitudes explores the microbes living in and around animals, showing how digestion, immunity, development and behaviour depend on relationships that blur simple boundaries between organism and environment. An Immense World turns to animal senses, moving through ultraviolet vision, echolocation, vibration, smell, electric fields and other ways of perceiving reality unavailable to humans.
