It is a pleasure for me to acknowledge the contributions of many people to this book. My parents and my teachers at Roxbury Latin School taught me how to pursue interests along many lines simultaneously. My debt to my many New Guinean friends will be obvious from the frequency with which I cite their experiences. I owe an equal debt to my many scientist friends and professional colleagues, who patiently explained the subtleties of their subjects and read my drafts. Earlier versions of most of the chapters appeared as articles in Discover magazine and in Natural History magazine. I have been fortunate to have as my editors Leon Jaroff, Fred Golden, Gil Rogin, Paul Hoffman, and Marc Zabludoff at Discover, Alan Ternes and Ellen Goldensohn at Natural History, Thomas Miller at HarperCollins Publishers, Neil Belton at Hutchinson Radius Publishers, and my wife Marie Cohen.
