P REFACE

Nineteenth-century evolutionists envisioned the earth as a grand laboratory or workshop of organic development: a shimmering sphere of life spinning in a vast universe. That image inspired a new way of understanding nature. It changed how we view ourselves, one another, and all living things. We became interconnected competitors rather than separate creations. We now live in the shadowor the illuminationof this modern biologic worldview.

The history of modern evolutionary science does not begin with Charles Darwin or even with biology. It begins with breakthroughs in late-eighteenth-century geology and paleontology. Indeed, when Darwin converted to an evolutionary view of biologic origins during the 1830s, he viewed himself as much as a geologist as a biologist. Fortunately, at the time, he did not have to categorize himself with either label, but instead could adopt the broader-brush title of naturalist, which encompassed the various fields of scientific study that he drew upon in formulating his theory of evolution by natural selection.

Darwins theory ripped through science and society, leaving little unchanged by its force. For nearly a century, scientists disagreed sharply among themselves over how evolution operates. Within the scientific community, a consensus answer to this question only began emerging during the 1930s, when a deeper understanding of genetics gave birth to the modern neo-Darwinian synthesis. Scientists still debate the details of evolutionary theory, however, and for many the devil lies in those details. Within the general population, disagreement continues even over whether species evolve, and most particularly over whether humans (or the essence of humanity) originated through purely natural processes from other forms of life. The stakes are enormous; few ideas more profoundly influence us than ideas about our origins. A starting point for any discussion of organic origins is an understanding of how the modern theory of evolution developed. It is a remarkable story of self-discovery that generated concepts affecting the very notion of what it means to be human. And it is far from finished. We will continue to learn more about organic originsand about ourselvesfor as long as we keep our minds open to new ideas in science.
