In the preface to The Making of the Fittest, Sean B. Carroll writes, "With DNA science penetrating so many facets of everyday life, it is again time for a new departure and to seek facts of a new kind. My goal in this book is to present a body of new facts about evolution gathered from DNA evidence. ... The body of new evidence I will describe in this book clinches the case for biological evolution as the basis for life's diversity, beyond any reasonable doubt." "With fervor and clarity, Carroll amasses a glut of facts to refute the twisted logic of the anti-Darwinist camp," applauded the reviewer for Discover.
