The Intelligence of Living Things: What Organisms Without Brains Reveal About Adaptation

A brain is not the only way to meet a changing world.A bacterium finds a useful direction. A slime mold reorganizes a living network. A plant carries the effects of winter into a later season. A single cell rebuilds a missing structure. How do these achievements happen-and what should we call them?In The Intelligence of Living Things, Danish Ali Bajwa explores the science of adaptive behavior in organisms without brains. From microbial communities and growing roots to fungal partnerships and cellular regeneration, this accessible book follows the mechanisms behind some of biology's most surprising capacities.Discover how local sensing can guide movement, how a body can preserve a trace of its past, and how variation can help populations survive without predicting the future. Explore the experiments behind maze-solving slime molds, rapid plant signals, and disputed claims of plant learning.The book also examines what biology can offer engineering, including growth-inspired robots and materials that respond to their surroundings. Throughout, it separates demonstrated behavior from speculation about thought and consciousness.Written for curious readers of popular science, biology, and the natural world, these twelve chapters combine research vignettes, clear explanations, and original thought experiments. Numbered references provide a route into the studies, while careful discussion makes room for both striking findings and unresolved questions.The result is an invitation to look more closely at life: to notice intelligence as a question, adaptation as a process, and wonder as something that becomes stronger when we understand what the evidence actually shows.
