The extraordinary story of how the human brain evolved... and is still evolving. We've come a long way. The earliest human had a brain as small as a child's fist; ours are four times bigger, with spectacular abilities and potential we are only just beginning to understand. This is How the Mind Changed, a seven-million-year journey through our own heads, packed with vivid stories, groundbreaking science, and thrilling surprises. Discover how memory has almost nothing to do with the past; meditation rewires our synapses; magic mushroom use might be responsible for our intelligence; climate accounts for linguistic diversity; and how autism teaches us hugely positive lessons about our past and future. Dr Joseph Jebelli's In Pursuit of Memory was shortlisted for the Royal Society Science Book Prize and longlisted for the Wellcome. In this, his eagerly awaited second book, he draws on deep insights from neuroscience, evolutionary biology, psychology, and philosophy to guide us through the unexpected changes that shaped our brains. From genetic accidents and environmental forces to historical and cultural advances, he explores how our brain's evolution turned us into Homo sapiens and beyond. A single mutation is all it takes.

No other life form on the planet has generated a brain like ours. How did a bundle of cells weighing just 1.2 kg give rise to conscious, self-aware beings capable of understanding time, language, mathematics and music, of exploring outer space and sequencing their own DNA? The answer to such questions is a 7 million year saga. How the Mind Changed is the definitive book on human brain evolution: a sweeping natural history. Beginning with the first primate brain and the rise of our present-day, large human brain, it will describe the remarkable origin of our species' most mysterious organ, how it has developed, and how it will change in the future. To study the brain is to study the essence of what makes us human.
