's review of the book stated that it contained "no weighing of evidence, no careful reading of literature on all sides, no full citation of sources (the book does not even contain a bibliography) and occasional use of scientific literature only to score rhetorical points." Gould also pointed out that the use of legal criteria, in which a "shadow of a doubt" was enough to destroy a theory, was inappropriate in science since "science is not a discipline that claims to establish certainty".

 improperly "defined 'science' in such a way that [it was impossible to] dispute the claims of the scientific establishment" and a rule it proposed against "negative argumentation [eliminated] the possibility that science has not discovered how complex organisms could have developed." Johnson believes that one cannot begin an argument with the assumption that this kind of definition of science is inherently true. Therefore, these are the kind of definitions and postulates he purports to examine, asking, "When the National Academy of Sciences tells us that reliance upon naturalistic expectations is the most basic characteristic of science, is it implying that scientists somehow know that a Creator played no part in the creation of the world and its forms of life? Can something be nonscience but true?" Darwin on Trial includes Johnson's examination of evidence and arguments about natural selection

Reception

Darwin on Trial has sold over 250,000 copies. Causing "an uproar in some scientific and literary circles," Darwin on Trial alerted national media to the creationist movement and their fight against the theory of evolution. In the year after Darwin on Trial was released, many articles about the controversy were published in popular newspapers and magazines across the country. Johnson said in an interview in California Monthly that he fully expected to be labeled a "kook" by the academy, but he was "pleasantly surprised by the support he's received from people familiar with his book on the Berkeley campus."

The book initially received more attention from popular media than from the scientific community

In "research notes" in the second edition, Johnson provides answers to most of Gould's criticisms, but acknowledges that his use of "polyploidy" was indeed incorrect, the error having been missed by his "diligent scientific consultants;" it is corrected in the text. Johnson also replied in an online posting, essentially repeating the assertions he made in the book. Robert T. Pennock

 has pointed out that the book repeats many arguments by creationists that were previously discredited:
Scott further criticizes Johnson's approach, which assumes science and evolution can be treated the same way as a criminal trial. Scott points out that the uses of three critical terms in both science and law are completely divergent. Within science, a law is a descriptive generalization, while a theory is the explanation of the law, and the term "fact" is rarely used (in favour of "observation"). In comparison, the legal term law refers to a rigid set of behavioral proscriptions, a theory is presented by a lawyer in an effort to convince a judge or jury, and facts are assertions that lawyers make and attempt to prove to the court. Scott points out that in science, facts and theories are changeable as knowledge accumulates, and laws are less important than theories, while in court cases laws are immutable, theories are secondary to the laws. Also demonstrated is how the adversarial process works in each profession; during trials lawyers will actively conceal weaknesses in their cases and relevant information from the jury, while science is strongest when it actively attempts to disprove its own theories; a scientist concealing information will ultimately be exposed and disproven. Scott also points out that Johnson criticizes the theory of evolution for changing to accommodate new data, indicating a profound misunderstanding of this strength of science which must adjust theories in order to explain contradictory or new information, and the false dilemma

, and

Scott further states that Johnson lacks familiarity with the specifics and nuances of the field necessary to match the critiques of Darwinism offered by evolutionary biologists, and instead parrots the criticisms made by suspect sources (scientific creationists). Scott lists a series of examples demonstrating that "[Johnson] clearly does not understand the meanings scientists give to many of their terms [and] deliberately conflates pairs of ideas that properly are separate", then concludes "Darwin on Trial deserves to be read by scientists, not for its scientific value which is negligible, but for its potential social and political impact."
