"Until the past decade and the genomics revolution, Darwin's theory rested on indirect evidence and reasonable speculation. Now, however, we have begun to scratch the surface of direct evidence, of which this book offers the best possible treatment. Though many critics won't want to admit it, The Edge of Evolution is very balanced, careful, and devastating. A tremendously important book." -- Dr. Philip Skell, Evan Pugh Professor of Chemistry, Emeritus, at Pennsylvania State University, and member of the National Academy of Sciences
