This novel is entirely fiction, but in writing it, I have drawn on the work of researchers in many different fields. I am especially indebted to the Work, and the speculations, of John Alexander, Mark Boguski, Edwin Colbert, John Conway, Philip Currie, Peter Dodson, Niles Eldredge, Stephen Jay Gould, Donald Griffin, John Holland, John Horner, Fred Hoyle, Stuart Kauffman, Christopher Langton, Ernst Mayr, Mary Midgley, John Ostrom, Norman Packard, David Raup, Jeffrey Schank, Manfred Schroeder, George Gaylord Simpson, Bruce Weber, John Wheeler, and David Weishampel.
It remains only to say that the views expressed in this novel are mine, not theirs, and to remind the reader that a century and a half after Darwin, nearly all positions on evolution remain strongly contended, and fiercely debated.
