From a different perspective, paleontologist Charles Marshall wrote in his review "When Prior Belief Trumps Scholarship" published in Science that while trying to build the scientific case for intelligent design, Meyer allows his deep belief to steer his understanding and interpretation of the scientific data and fossil records collected for the Cambrian period. The result (this book) is selective knowledge (scholarship) that is plagued with misrepresentation, omission, and dismissal of the scientific consensus; exacerbated by Meyer's lack of scientific knowledge and superficial understanding in the relevant fields, especially molecular phylogenetics and morphogenesis. The main argument of Meyer is the mathematically impossible time scale that is needed to support emergence of new genes which drive the explosion of new species during the Cambrian period. Marshall points out that the relatively fast appearance of new animal species in this period is not driven by new genes, but rather by evolving from existing genes through "rewiring" of the gene regulatory networks (GRNs). This basis of morphogenesis is dismissed by Meyer due to his fixation on novel genes and new protein folds as prerequisite of emergence of new species. The root of his bias is his "God of the gaps" approach to knowledge and the sentimental quest to "provide solace to those who feel their faith undermined by secular society and by science in particular".
