Today the theory of evolution by natural selection and the science of genetics are the twin keys to our understanding of how life on earth came about. Yet when an English naturalist called Charles Darwin first published his ideas in 1859 in a book called On the Origin of Species the world was horrified at the notion of a changing creation without the intervention a Creator. By contrast, when a few years later an obscure Moravian monk, Gregor Mendel, published the results of his experiments in genetics the world failed to notice John Scotney's new book explains just what these two great men had discovered and follows the amazing development of this seminal idea from the decade when it turned the world on its head to the present time and the unravelling of the human genome. It describes how the first dinosaur fossils were believed to be the bones of giants and how little by little the ongoing story of living creatures has been assembled until we can see the thread of life running from single-cell microorganisms to primates like ourselves, and why most ancient creatures died out and some survive to this day. Indeed we still carry vestiges of former life forms in our bodies and it is said that ancient seas flow in our blood. Anatomy, taxonomy, chemistry, geology, archaeology, and embryology have all had a part in this remarkable detective story, and even the Cold War became involved when the followers of Mendel in the West were confronted by those of Lamarck in China and Russia. Modern evolutionary theory is shown to be a synthesis of many scientific fields and the product both of years of tireless work and of sudden imaginative leaps. The Theory of Evolution conveys the excitement of this fundamental discovery and gives an insight into the way scientific enquiry and debate continue to shape our world.

Since returning to England he has combined teaching with writing and producing for the BBC. He has taught at the University of Westminster and on courses accredited by the Universities of Manchester and Kent, and for San Diego University, California, he taught a summer school on the history of ideas, with particular relevance to science. He has edited a History of World Literature and contributed to many journals, magazines, and textbooks. Among numerous programs he has written and produced for the BBC are a series about the scientific and technological background to the Industrial Revolution, and for Radio 3 "Our Green Survival Kit," which told of the continuing role of phytochemistry in medicine. His Radio 4 program, "A Mind of Universal Sympathy," was a portrait of Charles Darwin's grandfather, Erasmus Darwin, who anticipated many of his grandson' s ideas.
