Creatures of Accident: The Rise of the Animal Kingdom

Wallace Arthur, . . Hill & Wang, $25 (255pp) ISBN 978-0-8090-4321-7

A core tenet of the intelligent design movement is that some organisms are simply too elaborate and complicated to have evolved by chance. Arthur, a professor of zoology at the National University of Ireland, Galway, aims to render this strain of creationism unnecessary by "explaining, in a way that is accessible to a general readership, how the rise of complex creatures can be explained in terms of natural processes." Creatures of Accident makes this case through a series of easily intelligible, chatty chapters, offering a way of understanding the emergence of animals (the most complex life form) without resorting to either the relativist idea that all life is essentially the same (with animals being, as Stephen Jay Gould once put it, "a mere epiphenomenon") or the teleological view that if animals are uniquely complex, then some intelligent designer must have made them so. Drawing ideas and examples from the large (zoology) to the small (cellular biology), Arthur popularizes recent breakthroughs in the field of evolutionary development—the trendily dubbed "evo-devo"—to make the paradoxical case that complexity can, in fact, happen quite simply.
