David N. Reznick is professor of biology at the University of California, Riverside.

"Rzsnick's book is useful in giving lay readers a clear view of the main lines of modern evolutionary biology."---George Levine, Victorian Studies --- "Reznick's metatext [has] intrigue and appeal and provides value-add. Last but not least, worthwhile future research projects include in-depth explorations and comparisons of Reznick's metatext to other recent commentaries (and metatexts) by giants of the Darwin Industry."---Rasmus Grønfeldt Winther, Metascience --- "There is clearly a need for the general public to understand what Darwin did or did not say, and Reznick's interpretive guide is a great place to begin. . . . Then and Now is an excellent book. Reznick offers insightful analysis and compelling present-day examples, and is wonderfully readable in the process."---Piers J. Hale, Reports of the National Center for Science Education --- "Reznick attempts to recast Origin in a more contemporary and useful form, integrating both new ideas and new data. He accomplishes this goal in an admirable fashion. . . . The Origin Then and Now is a significant book of value to many diverse audiences. . . . We can hope that Reznick's admirable volume will convince his lay audience that not only is Darwin's theory one of the central concepts of science but that it must be included in any worthwhile science curriculum."---George E. Webb, Evolution Education & Outreach Journal --- "David Reznick succeeds in producing a highly engaging and informative 'interpretive guide' to the original On the Origin of Species with an approach that will prove quite useful in different ways to different groups of readers. Those who have read Darwin but perhaps lack knowledge of contemporary evolutionary biology will find the case studies, examples, and discussion of modern context highly instructive; modern biologists will gain much insight into the state of evolutionary thinking at its genesis, à la Darwin. . . . I join Resnick in hoping that his interpretive guide will inspire readers to pick up the Origin and enjoy Darwin with a whole new level of comprehension and appreciation."---James T. Costa, BioScience --- "During the past decade, a number of writers have hoped to rectify this situation with books that summarize, modernize, or otherwise elucidate this seminal work of evolutionary biology. Within this growing corpus of 'guides' and 'companions,' this new book by Reznick (Univ. of California, Riverside) occupies a place somewhere between the easygoing narrative of Darwin's Ghost by Steve Jones . . . and the scholarly analysis of The Cambridge Companion to the Origin of Species, edited by Michael Ruse and Robert J. Richards. . . . Major post-Darwinian concepts are discussed as needed to explain the modem repercussions of the Origin. Overall, this is a very readable and insightful guide that will provide readers with both the understanding and the motivation to tackle the original. Summing Up: Highly recommended. All levels of academic, public, and professional libraries." --- "Reznick . . . succeeds where others have failed--instead of annotating the dense, Victorian prose of the Origin or recasting it as a popular narrative, he paraphrases each chapter of the book, adding fascinating elaborations on why Darwin chose a certain phrase, where he turned out to be wrong, and how the intervening 150 years have changed our theories. His account is a welcome tool for those who'd like to hear evolution from Darwin himself but find the master impenetrable."
