Biology Subject Guide

It is a shared journey of discovery; step-by-step Nurse illuminates five great ideas that underpin biology—the Cell, the Gene, Evolution by Natural Selection, Life as Chemistry, and Life as Information. He introduces the scientists who made the most important advances, and, using his personal experiences in and out of the lab, he shares with us the challenges, the lucky breaks, and the thrilling eureka moments of discovery.
