In this book, Jos Verhulst expands on the evolutionary theory first proposed by Louis Bolk. The theory is based on the premise that aspects of the individual creatures' development -- from juveniles to adults -- are also at work in animal evolution as a whole.

Verhulst shows that, unlike other primates -- who start out with a rather humanlike form but become, say, apes -- humans retain their original fetal form. Standing Darwinism on its head, he argues that humans have not descended from apes, but rather that apes have evolved by diverging from a humanlike prototype.

He also proposes that the gradually emerging human prototype is the driving force, and central trunk, of the evolutionary tree -- the wellspring from which the animal world has sprung.

'Most remarkable is the way in which Conford demonstraes the rich interactions between the organic movement and wide range of other tendencies in intellectual endeavour, social and economic change, and politicalo struggle.'
-- Timothy Cooper, University of Exeter

'A tour de force: a refreshingly original, profound and thought-provoking synthesis rooted in impressive scholarship. Creative science at its best.'
-- Martin Lockley, Professor of Palaeontology, University of Colorado

'An astounding wealth of little-noted facts. Though some readers may not agree with his conclusions, all will find the rich content extremely thought-provoking.'
-- Wolfgang Schad, Professor of Morphology and Evolutionary Biology, University of Witten, Germany

'Verhulst argues convincingly that there is more to evolution than just Darwinian natural selection. If you are in any way curious about our origins, I invite you to read this book.'
-- Kenneth J. McNamara, Senior Curator, Invertebrate Palaeontology, Western Australia Museum
