Evolution is one of the most important processes in life. It not only explains the detailed history of life on earth, but its scope also extends into many aspects of our own contemporary behavior - who we are and how we got to be here, our psychology, our cultures - and greatly impacts modern advancements in medicine and conservation biology. Perhaps its most important claim for science is its ability to provide an overarching framework that integrates the many life sciences into a single unified whole. Yet, evolution - evolutionary biology in particular - has been, and continues to be, regarded with suspicion by many. Understanding how and why evolution works, and what it can tell us, is perhaps the single most important contribution to the public perception of science. 

In this book, Robin Dunbar uses examples drawn from plant life, animals, and humans to illustrate these processes. Evolutionary science has important advantages. Most of science deals with the microscopic world that we cannot see and invariably have difficulty understanding, but evolution deals with the macro-world in which we live and move. That invariably makes it much easier for the lay audience to appreciate, understand, and enjoy.
