An exceptionally fine presentation of the life and work of this great giant of the natural sciences by a renowned Fellow of the Royal Society who himself has received the Darwin Medal for his studies in the field of evolution. More a biography of the scientist and his discoveries than the man, de Beer concentrates on showing how Darwin's thinking proceeded as he explored, recorded, experimented and carefully and laboriously thought out his ideas about evolution. There are strong glimpses of Darwin as husband, father, and friend, but we see him most clearly as a meticulous scientist studying every aspect of nature that could give him clues to the characteristics of natural selection. This is an accurate, serious, yet modest biography that usefully relates Darwin's ideas to modern genetics and the work being one in molecular biology. It can provide an excellent introduction to a more detailed study of any aspect of Darwin's work. Generously illustrated with photographs and diagrams and maps. A volume in the British Men of Science Series.
